Good Box

Great box does well with my subs would buy again

Heavy Duty!

I would recommend this product for the guy's out there that are serious about their music. If you got good, high quality subs, then this box will make them perform to your sub's max output with out worry of blowing up your box.

Good

This wire is very flexible and fit nicely in my 2000 nissan maxima. ring terminals were a little fussy, but that was operator error. very nice 150 amp fuse. Lots of wire crammed into it. Very inexpensive for the quality. I would recommend this to anyone looking for an upgrade.

good box

I bought this box for 2 12" kicker cvx subs 750 watts a piece its a great closed box for them especially stuffed 1/4 with pillow stuffing.. looks real good to.. quick shipping

good value

product worked for my new hifonics subs. that will be a winter system for my ride so i don't have to keep my main subs in all year round. i really like it mostly because its has black carpeting.

The Box that Rocks

Appears to be fairly well built. Arrived with a little dent and a tear but its too little to bother with. Sounds nice but doesn't hit as deep as I would have liked. Small size however, leaves me some room for a couple of bags of groceries. Three stars for durability since I've only owned this for about a month.

Amazing Enclosure, Even Better Price.

Ordered this as my first enclosure, put two 12" subs in it and I haven't found a box that hits as hard and as clean as this one has. Will definitely buy from SonicElectronix again for my car audio needs.

great box

Very sturdy well built. Allows maximum bang. Great price under $60

Fast and easy great buy

I got my complete set up: 12" kicker subs box 1000watt Mbquart amp and amp kit. I have always installed my own equipment, I found it helpful that they have videos that covered some of the product they carry. There are a few shop's in Texas like Best buy and Custom Sounds that offer equipment. But the professionalism of the knowledgeable staff the price and the reliability made it clear that I wanted to do business with them.

solid sealed box!!!

Cant beat the price. But it is really very good box. I put two 12" hifonic,also bought from here, with a 2 channel 1000 watt amp.It really shook my rearview mirror in my '97 towncar. My brother loved it so we put it in his '92 prelude.Wow!!! You can hear him before you see him. Great buy!!!

Great

It is what it says it is.. no problems with install.

a great kit for the price

these are great for the money and would definitely buy again

Its a box

have kicker 12, they sound alright have some loose paneling in my car, so I'm having trouble getting the clarity I want. over all its a box and it works.

Decent Amp Kit

I am a professional installer first of and my father is an electrician. Following the AWG- American Wire Gauge standards this is not 1/0 wire it's closer to 2AWG, please understand that true 1/0AWG copper wire will cost around $5-8 a foot.

That being said for the price it is an amazing kit but should be marketed as 2AWG.

When compare to Kicker and Memphis true to spec 1/0AWG wire there is a major difference in size and weigh over all. 5 feet of Memphis 1/0 Wire weigh the same as 17 feet of Belva 1/0AWG.

Great Wire

It's the size it says it is, and powers my 1400 watt system with no problems. For the price and ease of install, I couldn't be happier!

top quality

I got this kit on a deal with a amplifier I purchased thought it looked good turned out to be one of the best amp kits I have ever owned would of paid full price for it

Great deal

I got this kit because I got a deal on it with my amp...great starting kit...didn't have any problem with it when I installed it...The ground cable was to short for me but that is due to my custom box..All in all good 1/0 Guage kit

good product

Good product, they give you plenty of length. Only complaint is that the o connectors are really hard to clamp down and the rcas are kinda cheesey but work

Huge

I have never ran 0 gauge before and when I got it and took it out I was surprised but the big wire didn't really hurt the install it is still hidden under the carpet and it's thick and flexible so it was easy to run through the firewall. Now I'm gonna get the Belva big 3

True 0 AWG!

Pros:
This kit comes with everything you need for a 0 AWG amp install with RCA inputs.

Cons:
NONE

I would definitely recommend purchasing this kit if you need a quality 0 AWG kit at a fair price with super fast shipping!

Great box

I have this box with 2 kickers 12 in back of a Nissan altima and they soundgreat. Would recommend to anyone and would definitely buy again. Sonic electronix is the best

Great Box

I ordered this for 2 crunch gpv's about six months ago because I didn't have the tools to properly build my own box. After six months this box is still holding up and works perfect with my subs.

Awesome "BANG" for your buck

I am on a budget, like most of us. I needed a nice looking box for a reasonable price. For $52.00 you can't beat it.
I loaded my 2 12" Alpine TypeS subwoofers in it. Mounted my amp to the back and they are still going strong.

bangn

Love it nice size for my subs still banging the same system

Solid Box

Ok so I bought this box because I wanted a quick sealed enclosure for my 2 JL W3's. The box is made pretty solid, true 3/4 MDF but the caulk job on the inside was kind of off but that's nitpicking. Haha after 3 weeks though of pushing my W3s the top of the box is leaking air. So not the best made but definitely a good pre fab and pretty cheap. Can't really complain. It is nailed together tho so yea..

It's a box without a hole

Solid sealed enclosure. Two of them barely fit in the back of my 02 Focus SVT 3 door. The binding posts are cheap, I tightened them as I would other posts but one out of eight wouldn't tighten because the thread tolerance is poor and it acts like its stripped, I can get some pressure on the wire but I worry it will come loose. Probably worth spending a little more money on a better enclosure but it works fine if you're on a budget.

Belva BAK02

For anyone looking for a budget amp kit, this is it. It is TRUE 1/0. I even measured it. Just got it in the mail after about 5 days total since ordering. Shipped very fast; thanks Sonic Electronix. Awesome deal, nice and beefy wire.

very good sub box

The box is very good at 1.25 cubic feet. I'm running 2 12's with 800 watts rms and it hasn't shattered. Wish it was 1.35 cubic to accommodate for subwoofer basket displacement but it still makes makes subs hit ridiculously hard. Polyfill helps make the box seem bigger due to mechanics and the "Q" point. I really couldn't be happier!

Great Value!

I ordered this item for my grandson and he loves it.

Good value, good quality

Bought the MDFD12 for my son. Installing the subwoofers was very easy and the enclosure looks great. Highly recommend.

Belva Amp Kit

Good product. Quality parts.would recommend to anyone needing a 0 guage kit for a good price.

good box

It is a good prefab sealed box. I looks good and is functional.

Great Value

Great items from this place, more orders will be goin from me.

good box cheap but good

this box is deferentially cheap but i put my 2 kicker comp 12's in there makes the sound good but i am thinking of getting a ported box soon, box is made with good material and i like it have it wired down to 2 ohms its sound good

GREAT KIT FOR THE MONEY !!

Good kit , ive seen better but not for the price . Well worth the money!

Belva MDFD12

Belva mdfd12 12" box is good quality and good affordable price really good size an make my subwoofer sound amazing... 5 star

great amp kit

The power wire is real thick, looks like a great amp kit, Rca cables look awesome. Only thing that would make this amp kit better would be to include speaker wire. Crimp terminals are a bit hard to install
But over all great amp kit.

WOW Great Quality

I purchaced your Dual 12" sealed sub enclosure and added two Alpine R's and fosgate 1000w amp and WOW does not even come close, it Rocks. The quality of the box is really really impresive. The carpet in not the junk material I've seen in my other buddies combo's.
When you buy this box you know it will deliver and last a long time.... Sonic, keep up the good work!

Dual 12" 3/4" MDF Sealed Subwoofer Enclosure

If you are looking for a quality made box this is it !! I was very impressed with this box the moment I opened it.

The WOW factor was at least a 10.5 on the 1 to 10 scale. I WILL BUY AGAIN .

quality product

This enclosure is a well built enclosure for sq applications. I purchaced to house 2 CV vmax 122 drivers and the sound quality was almost rubbery? not tinny, never a crackle....fluid almost..... call it a well dampened sound with minimal distortion. just clean bass all the way into the 20s. made sounds i diddnt know existed. if you dont care how your music sounds and just looking for loud, look elsewhere. my only complaint, 11" cutout is too small for the vmax and the black carpet is difficult to follow a line with the router.

Great Sound!

i have 2- 12 inch Memphis audio 15-M3124D's in this box each putting out 2000 watts max hooked up to a MA audio HK10KA amp rated at 10,000 watts max. i have the subs bridged and it has way too much power going to them but the box still stands up. i would recommend that when you install your subs that you put some sort of foam stripping underneath the lip so when you screw it down you wont have and leaks at all.

Sleak, Sexy, Soundiful!

Its cheap, in price. Yeah, we see that. But let your worries go to rest, this is a GREAT BOX. Its well made, and put together great. Although they did use nails instead of screws, if you know what your doing, it won't slow you down. I have 2 12" Kickers in this baby, and pounds like a mofo.

Get this box. You won't be disappointed.

Best box for the price.

good box

I bought this box to house two Pioneer TS-W309D2 subs. Box has a solid construction. I could not feel any air coming from the seams.

GREAY BUY!

I put 2 P3 dual voice 12's in this box and they sound awesome .. cant beat the price.. the quality is there

Great box

Runs 2 Rockford Punchs in and no air leaks and bass is clear as hell. Any 12 would sound great in this box, would buy again if it ever goes bad.

Good product

Built very sturdy except for the terminals. Its easy to switch those out though so no complaints. Thanks Sonic!

A little trouble at first...

The whole was no the size it said it was. I happen to be a part-time handy man so I had a circular sander and was able to make the whoel bigger. Took about an extra 20 mins of work to mount the subs, but overall everythign worked out. No complaints about box. It is doing it's thing!

good cheap starter box

i bought this box about a year ago for 2 of my infinity reference 1260w subwoofers. I have two more in a ported box. im pushing 350w to all 4 and I have to say I like this box more than the ported. you feel it more in the sealed box but lose a little on the db's but its worth it. the box is sturdy and hasn't showed wear a bit. its tuned in the lower 40's so you wont get stupid low with it but can get loud. I would recommend it to anyone on a budget or to lazy to build their own box. it comes with polyfill which is a bonus, the terminals on the back need calked but that's with about any box you buy. overall I like it and would buy again if I had to.

Great kit

The kit is good has mostly everything you need
, although I recommend getting a longer ground wire due to it being short , only downfall other then that great kit for a sub amp n other amp install worked great for my sub amp and 4chanell although I needed a few more wires for adding the second one

soso box!

Nice and built! really small box, has nice and deep sound... but the 12in kicker crvs need more space I think

Works just fine!!

No problem with install or power. Everything needed was right in the kit. I would buy this again if I needed it!

GOOD KIT

IT IS A GOOD KIT FOR THE MONEY. THE TERMINALS COULD HAVE BEEN BETTER. THEY COULD HAVE SUPPLIED BETTER 0/1 GUAGE TERMINALS THAT WERE EASIER TO USE BUT STILL A GOOD PRODUCT.

Great box

Great box for the price and it can fit in any trunk.

Real heavy duty kit. Real amount of 0 Gauge included.

This is a very heavy duty amp kit. The wire is huge compared to other brands I've used in the past. It's flexible and easy to install. And it's really a lot cheaper priced than other top brands. The fuse holder is nice too and I like the color of RCAs. Like everything with Sonic, always fast shipping and great stuff.

Order

Never revieved I have a trache and am unable to speak on phone I sent you a letter but no response yet it wouldn't submit my review till I checked start I can't answer when I have not recieved it.

great!!!!!

was just the right amount of space i needed for the 12's

ok so far

Installed this weekend, I did add a couple pounds of "pillow stuffing" since the box was a tad smaller then what I needed. I have noticed some flex already but im not suprised with the subs that are in it. I will add triangle shaped gussets and some "trim screw" to try and hold things together.

A sheet of real MDF (not the cheap underlayment) is $32, carpet and glue around $15 so for what they want for this its a good deal that just needs some minor tweaks.

Kick a**

The sub box was really good.

Okay

The box is leaking now. But the price and design was worth it all in all; it's just due to be resealed.

Perfect

Not much else to say besides great product. Shipped in only 3 days, and the pre-done polyfill is a great touch. My only comlaint would be that my car smelled like glue for a few days after I put this box in, but that's just nit-picking. Will definitely order boxes from Sonic in the future!

Sub Enclosure Review

Perfect size to fit my Infinity subs. Wish it came with mounting feet but can't ask for everything. Quality is legit for the price. Just your average rectangular box. Fit in the trunk of my 240sx which is pretty small.

Great Box

Subs fit great and the construction was sound. Thanks Sonic!

GET WHAT YOU PAY FOR!!

This box looked great and felt very durable. My subwoofers wouldnt fit at first so I had to do some shaving, NO PROB. It sounded good for awhile and I loved it. After about two weeks, it lost its sound, went to check out the problem the whole front of the box had almost came off, Box was sealed very well, too bad they used nails instead of screws, would have been a very good box.

Nice Box

This box is pretty clean...nice black fabric, enough to hold the subs and gives them enough air to makes the subs bump and bump and bump and bump! Good buy at an unbeatable price. Awesome.

Great box

This is a great box. I prefer ported but my trunk is too small for it so I had to go with sealed. I'm still happy though. This had the perfect size for my 12s. Also the measurements are a little off. The box is a little bigger that the description said.

not what u expect

I would not recommend this product because. It I only a little bit bigger than four gauge. I do not know how they market this product as zero gauge. Next time I just have to spend the extra couple of bucks.

Great Subwoofers

Everything was going perfect with the two sub woofers i purchased. Great price & everything. But then someone stole my car & the woofers were in it. Anyways, they were GREAT while I had them.

Great

This is a great sub woofer box for the price it is heavy 41 pounds and it is sturdy. I have 2 12 kickers 600 rms 1500 peak and they sound great in this box hits lows and highs hard. I would say to any one buy it.

Okay Box

had to trim the 12" hole for my Sound stream PCO.12 subs they wouldn't fit at all. once I trimmed the MDF I love this box. they could have used spring term instead of screw though.

Budget amp kit *thumbs up*

This is a good quality budget amp kit. Power wire is almost true size and soft and flexible. Everything was exactly as described and no issues at all getting my system installed with this kit. The twisted pair rcas are nice and I have no noise pickup with them. There was even enough power wire left over for me to grab a few extra ends and do the big 3. Definitely recommend.

Great price for this box, very reliable. I put 2 lanzar 15s in here and they sound great, would highly recommend buying this and not wasting more money on a more expensive box

great box

this box is light weight. its made strong and fits every sub ive ever used in it.

nephew

My nephew loved this product along with the Autotik amp and Kenwood subs for Christmas. I even upgraded my old amp with a 4000 watt PZX Crunch amp to keep up with my nephew and his system lol

Great Budget kit, with a few shortcomings.

Overall this was a very good kit, with thick high quality wiring and heavy insulation. I saw no factory flaws, and since installing it I have had no problems. It did however lack a few things, which bugged me. The first was that neither: the ground, nor the power cable came pre-clamped, this wasn't a huge deal as I had access to a vice, but for those with limited tools, they may have trouble creating enough leverage to cramp the metal ends tight enough. Other then Having to clamp the ends myself (again, only an annoyance if you don't have access to good tools) the kit has performed flawlessly, and is a great value for the price.

nice & clean

I replaced my old box with this 1 & man what a difference. My old box was 11 years old & I didn't realize it was falling apart & with this new box I noticed an instant difference. Its a great box for the price, it holds firm & can handle the full pressure of 1100 RMS

I did have to spray a little adhesive inside for 1 part of the foam & terminals were screwed in & not exactly straight & I also had to poke holes in the foam for wires but these things are no problem. The box is awesome & I will by more in the future

Good Wire

I was skeptical about buying this wire, but to be honest it is definitely worth the money. I would invest in some new RCA's though, the ones that come in this kit aren't that good!

Good bang for the buck

It's tough to build a box for the price you can buy one of these. They are solid. I haven't had any issues with mine.

Good Quality

I would definitely recommend this box to a friend, Nothing like a good old professionally made box, I love the material that they put in it, it really adds to the sound.

Must Have!!!!!

This is an awesome enclosure. The price is very competitive as well. I am running 2 Rockford Fosgate R2D2-12 and there is no distortion at all. It is a very tight, clear sound. I highly recommended for anyone looking for a high quality low cost setup.

Good Sub Box

I like it, I think the covering looked good but I ended up messing it up trying to screw something into the outside. Otherwise i liked the box, my subs hit good in it.

Great Value

never bought another brand. belva has always been easy to use and held up very well

ELW1214.2 BOX

Superb Box! Tight sounding bass, and best of all deep rumbling bass. Excellent for an audiophile like me.
Easy to install and use!

AWSOME PRICE

Very good quality. Very flexible wire. Very pleased. Will be ordering again when i need it

Belva 2 12" sealed enclosure with my 2 12" Infinity Kappas

Great box, holes were perfect sized and nice mounting depth! My triple voice coil Infinity Kappas with the 1600w amp SLAMS!!!!

Pretty good

It was hard to install but when I did I got the extra burst of energy I need

Great 12's Box

This box is designed well. It is assembled, sealed, and carpeted very well. Speaker terminals are nice inside and out. Couldnt be any happier with this enclosure. Will use box with various subs.

Excellent!

Cheap and effective! This is truly one of the best boxes that i have bought for the price it is. Sounds great and made very well!

best box 4 the buck

Don't let the skimpy price fool you. This box is made very well and it's ready to go. The joints are already caulked and glued - so there is nothing more to do than mount you speaker.

It's not MDF(medium density fiberboard) like all the others, it is made from HDF; high density fiberboard. HDF boxes are typically stronger, stiffer, and lighter than MDF enclosures. The box does not require any additional bracing because of its density. It has a high an undetectable high frequency resonance and doesn't color the sound of your bass with unwanted buzzing or flexing. The HDF box is lighter than MDF because it has smaller fibers that when pressed and heated require less glue and resin to bind the fibers together.

The speaker terminals are screw type gold plated binding posts that will hold 12 g speaker wire easily. They screw into the enclosure for added strength and a tighter seal.

Just make sure that you do your math and pick the right sub for the cubic feet and stuff with poly fiber fill.

Awesome

Bought this for some 12" audiobahhn subs I bought 2 years ago still brand new in the box and hooked everything up in my 91 civic sedan to my
Hifonics BRX2000.1D Brutus Mono block and pure awesomeness. The box makes these subs slam. Highly recommend this box

bIG OTT

It is a typical wiring kit for a system. It is a little short in my 03 suburban, so I just mount the amps under my sets directly behind the drivers seat.

Extremely well built

Insanely well built box.

Carpet job is top notch, Good quality carpet stretched perfectly over the box. All joints are glued and caulked well. theres no need for extra bracing here but you may add some 2x4's to reduce the airspace if needed. The gold push terminals are well sealed in place.

Hits low and hard with all sub's I've thrown at it (JL Audio 12W04's, Rockford Fosgate P312D4's, Kicker CVX12's and finally Alpine SWX-1242D's)

Don't be afraid of the price. It's a perfect price for a box of this caliber. Would recommend it to anyone.

Tuff Stuff

Nice heavy, good sounding box. I would reccomend putting some polyfil to "cushion" the backfire of the subwoofer, really helps w/any sealed box and totally makes a valuable difference considering it only costs about 5-10$ more. The box itself is well sealed and well made, the connectors on the inside and out are really easy to use and once connected your wires will stay put.

Good Product Good Box

This box is great for the low! I don't have nothing bad to say about this product.... The sound quality is awesome with this sealed box.

By alan on June 18, 2015 Verified purchase

great sub, good deep bass

Pros: deep bass, can be loud or soft and sound good, box doesnt matter, sounds good in sealed or ported, only need 500 watts to get it pounding.

Cons: will blow easily if you try to run it close to max watts (stick with rms), doesnt have the high notes that other subs do (this is more of a rap sub than a rock one).

Good for the money

Bought this kit because of cost. Fuse holder is of good quality. RCA cable is nice. No noise. Plenty of remote wire for amps. Power and ground are very flexible. Wire gauge is a little smaller then zero gauge but not like some other kits. All the terminal connections are included. In the end, good product for the price.

this is a solid box

when i bought this box i wasnt really expecting much, because of the price an all but when i put my rockford fosgates's in it, it did sound great, and let me tell you im gettin 2 12 alpine type r next and im for sure going to be getting this box again.

so dont let the price scare you trust me you wont be disappointed

Good Box

I have this box with two hifonics subs, hooked up too a hifonics 1600 wat amp. Its a very good box and hits really good. Would approve to anyone.

Great Box

This is a well built box. Great quality carpet. If you want a good box without paying high prices this is perfect.

Your basic sealed box

Great box. Quality carpet job, all seams sealed correctly and well, and the terminals are strong and functional. Perfect basic box to make two twelve's hit perfectly. Just remember this is a sealed box, so it will have a differnet sound than that of a ported or bandpass box, but if u want a tighter hitting bass, this box if perfect.

Wire is great but terminals are hug

The wire is great and seems to be true 0 awg. However when going to crimp the open barrel ring terminals to it they are literally twice the size! Have to go buy new ring terminals that are the proper size.

Sounds awesome

I installed these in a SubThump box for 2013 silverado. powered by Rockford Fosgate R1200.1D amp at 1 ohm I like headroom so this setup works great.. They rock hard!!

Excellent product

I have this sub in a sealed box in my truck running at full power and it sounds very good. It doesn't distort at all and the bass hits very hard without any distortion. Highly recommended, I'm very happy with it.

Awesome

I love these subs. I installed these and ran each one off its own amp. I'm only giving each one 500w but these things bang.

Easy, cheap price, great quality

I bought this box for some Rockford Fosgate P1's and I couldn't be happier. The box is solid and produces some really good sound in my Audi.

Good quality

I was very surprised with the quality of this box. It was well made for it being a prefab box. The polyfil definitely gives the bass a deeper sound.

Excellent!

I bought this for my husband for his birthday and he loves it!

Best quality for its price!!!

I've been using this kit for about a while and the products are still in great shape. using it to power my audiopipe 3000.1D amp and two american bass xfl 15"s. wire in never hot. flexible. but the wire easily spreads apart for the cut tip/end if your not being careful and makes installing into amp/fuse box, etc ... more difficult.

You wont be disappointed

Have had mine for at least 3 months or so. I have an 1100 watt peak 550 rms amp hooked up to this and I am not gentle with it. Just one 12 in a custom ported box and this blows away my friends two kicker CVRs. Definitely worth spending the extra buck to get these. You wont be disappointed.

guy buy for the price

I bought 2 of these subs with a hifonics brutus 1200 rms amp and it was perfect for these subs.

Awesome subs

Put them in this afternoon and they bang hard

title

Great box well made great value enough said ten word review

Alpine 4eva

I have 2 12s wired down to 1ohm and I almost forgot what these sounded like! I owned 4 ran off 2 1500.1 kicker amps a couple years ago and they were dual 2 ohm wired to 1. Dual 4 put out the same head pounding bass, extreme lows with little or no distortion at high volumes. RE 1500.1 bridged are runnin mine. XS 1200v cell with .5 farad cap and yellow top optima for SERIOUS power. Sealed enclosure for my 97 continental.

Belva BAK02

Installed this wiring kit three weeks ago, very nice quality 1/0 gauge! Works great! Ended up buying some screw ring 1/0 gauge terminals because the crimp terminals it came with are a bit difficult to install. Other than that, very good product!

Hard hittin

Bought this along with an RF Prime R500.1 (528RMS).
At first I had this in a sealed box and I was happy. Then I got a ported 1.8 cu ft box and this thing hits so dang hard. When the back seats are down it shakes my winshield and side mirrors like crazy. So many people ask what I have in back and they are amazed when I tell em its only 1 12". This thing out does 2 kickers easily. Almost nothing can compete with this sub in its range. The only thing that you have to watch on this sub is the low lows. After playin rack city at max volume they started to smell a bit. For all other Hz this thing is a beast.

Make sure you get a box designed to spec!

I had one alpine type r in a walmart box and was very disappointed. So I decided to get a second one and put them in a ported box designed to spec. WOW what a difference. I was bumping so hard my rear view mirror fell off! I would definitely recommend this sub just make sure you buy a ported box from sonic instead of settling for a walmart box!!

Alpine Type R

If you want loud get these. They dont change notes very well between high and low hits but they are still loud. If your lokking for everyone around to hear you get these. Two of these in a ported box is all the bass you would ever need.

Sub box

Good product I would recommend this sub box to anyone that is looking for a cheap n quality enclosed

Good quality for the price

I have 2 12 pioneer ts-a30s4 and it's working great inside this box

good value

I bought this to put some ID Max's in for my daily. Build quality is good and the price was right. The box was good enough for me to buy another for some first gen JL Audio 12W3's that I was selling.

Solid Construction

I ordered this box for a pair of AudioFrog gb12d4-12, the box came with a couple of nicks from shipping. And didn't have the poly fill. Customer service was on point.

Good solid box

Its a great box... small compact and puts out great sound...A+ on this. Carpet matched my existing carpet turned out pretty great im happy with it :)

wiring kit

Great kit for the belva bb5000 wire size seems small but i just used it for the big 3 now im running skyhighwire still a great kit for a beginner just not for me

great product

Comes with literally everything you'd need, fits perfectly in my 2014 dodge charger rt. Only think I had to buy in addition was a gauge to be able to lower the volume on the bass. Other then that I love it!

Great value

Worked out great for me. Will be ordering a second

The item did not live up to my expectation because it arrived empty and damaged.
But for the price its a pretty durable box.

Excellent!

Great value box

Budget-friendly box great build quality has 2 12 at 600 RMS power the woofer box holds the pressure would recommend this box.

Fantastic Sub Box

A very well-built and nicely carpeted sub box, that looks great, and should prove to be very durable, as it is constructed with 3/4" MDF instead of thinner material of many other boxes costing more than this.

The black carpet makes more of an impact than the typical gray carpet, and the 5-way binding posts are much higher quality than the typical plastic spring connections normally found on sub boxes.

Very happy with this purchase, and would absolutely consider another should it fit my needs of enclosure volume. (It's not worth the extra time/effort to make a custom box, when this does the job just as well, and comes pre-lined with poly-filled and pre-carpeted)

Great deal

Love this box worth every penny really solid box everyone should buy it

Great Budget Box!!

Ordered my box and had it at my front door in 2 days! Great box. Its very well built and pure mdf and thick mdf wood. Nice carpeting. Only down fall i see is there was no poly fill and terminals are on sides instead of rear. I thought it was suppose to be this one pictured and both are the same numbers but different box but i am still very very pleased!

Sturdy enclosure

This is a very well constructed box, well sealed and solid. However, mine arrived new in the box and every corner had the carpet worn off and bare wood showing. Also, mine was not lined with poly-fil and the terminal cups were on the sides rather than in the back as it appears in photos- no biggy but that did influence my decision as my install would have been a little "cleaner". All in all it sounds great and seems extremely durable.

Awesome with my dual JL 12w6v2's

Purchased because I needed a new box for my JL Audio W6v2's. Sounds great! Great solid construction, nice that it's already lined with polyfill, no air leaks and the black carpet looks great. Can't beat it for the price and sound quality with my subs in it is excellent. Guess it would be nice if the terminals were pre-wired but I soldered my own wires in. Love it, would buy again Box fits perfect in my '13 Accord trunk

Tight Bass

I always try new subs in a sealed and then ported box. This Belva is a great value and a solid , sharp looking sub box.

Nicely built and good for breaking in any subwoofers. Highly recommended if you like that nice clear sound that cam hit that tight bass.

Great bang for my buck

I have to LMFAO at all those bad reviews bet they never realized 3 weeks. At lest before you go n turn up amp. Today is Aug 19. 3 weeks ago I bought n installed (DIY). My amp n remote were both turned to 2 gain will EVERYTHING ELSE was set 0. Yes at first could not hear it. But in long run worth it. By 5th day at 2 gain was raddling my mirrors. I only got one these bad boys. Due to out stock. I can't even fathom 2 these. Guys going.BTW I still haven't messed with amp or any settings. Pounder on that for awhile.....

I would reluctantly recommend this box. The one I received was already slightly damaged in the corner with carpet coming away from some of the seams in the corners even though it was brand new from eBay.

This wiring kit fulfilled my expectations . No noise interference and very high quality product !!!
I highly recommend this kit for anyone installing an amplifier in their car !

Simple and great product

This was a cheap and effective solution to hooking up my system only thing is it isn’t true 0 gauge wire however it does the job and I would recommend it.

By Clarence on September 7, 2023 Verified purchase

Says 1/0 gauge probably more like 2/0 gauge. Comes as you see in pictures.

Good item. Did the job like it was supposed to. Would purchase again from sonicex

wow got jipped

this wire kit is nowhere even close to 1/0 gauge. even if it was pure gold it is probably a strong 4 ga in a 1/0 wrapper. very flexible and nice looking. the fuse holder isn't too bad. eh, i got it on sale.

By Brandon on April 15, 2016 Verified purchase

amp wiring kit

this wire is seemed mighty small to be for being 0/1 gauge wire but still getting alot of wire for the money. just be ready to buy end for this wire to hook up your cap/amp because this wire for me was way to big to fit in any of the amps/caps holes/connectors for wires

Great Value.

This box is awesome for the Price. A little heavy and you must have enough room. It will fill a trunk or back of a SUV. I have two JL 12's ,which makes this a combination that beats. Low, long, stretched about bass that lets the neighbor's; who live a mile away, know you're coming.

Perfect fit for my car.Love the carpet cover.Would recommend you carry gray carpet covered boxes.

Good kit

For the price this item is great. It’s half the cost of a true 100% copper amp kit, which is why you get copper aluminum mix and cheap connectors. But like I said it’s perfect for the cost and works great

Made out of high quality mdf nice tight bass highly recommend this box

Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Solid product. I wouldn't put a subwoofer heavier than 30-35 lbs each in it thought. It's lined with polyfil so you'll have to cut a small hole where the terminals are but other than that it's a pretty good box for the price.

True 0 gauge

This is exactly what it says it is. I measured the wire itself at slightly over 3/8 inches. Which is exactly what 0gauge is. There are brands out there that are thicker, but they are oversized. Several companies make oversized power cables. But this IS true 0gauge.

Good Kit

This kit came with everything I needed to upgrade from my old wiring kit. It had a few things my old one didn't that would've been helpful if it came with some directions of sort, I figured it out but would've been nice. Also the wire terminals could be alittle better quality.

By Alex on August 5, 2017 Verified purchase

Best Value!

This was already the best deal for a 3/4" MDF dual enclosure I could find, everything else in this range is 5/8".

For the price I wasn't expecting much.
However When it arrived found it is of good build quality, with decent carpet.

They already lined the inside with polyfil, more added value.

Then to top it off, found it has really nice gold plated screw type wire terminals. Better connection and added peace of mind that connections will not come undone.

This is probably the best deal/value on the internet for a dual 12 enclosure. Probably why it's backordered at time of this review.

Very Happy!

Great value for the price

This wire kit comes with heavy duty wires and pushes my 3000 watt system with no problems.

Amazing Subs for the price

I had a hard time deciding if I should have gotten 2 or just 1. I ended up only getting 1 Alpine Type-R sub and this thing blasts! I'm running it off the Rockford R500 amp and it's perfect. So happy with my purchase.

Subwoofer enclosure

Good quality would buy again
Good prices
Always love sonicelectronix

in love

I have this hooked up to a Powerbass XAX-1200d or something like that and I'm so impressed with both. i have this in a sealed box in my prelude and its so loud! I have one of these and all my friends think its awesome and it hits the notes I want it to. its quite heavy...but then again its a sub haha but it looks clean in the car and makes my rear view mirror start to fall haha. Everyone at the installation shop I went to was asking what i had and were trading in their Kenwoods and MTX and Pioneers for this. highly recommend this sub. i have not looked back on my purchase at all. i just wish it was a little more flashy...i love the simplicity but a little something more i think would be acceptable also. btw i listen to all sorts of music. im from LA so im big on hip hop and rock. this sub in a sealed box with my amp is just perfect. GET IT!

Bass in the place London!!

Don't bother looking anywhere else. Just click and buy. This sub is mental, an it keeps on going and going, giving birth to hard, deep and tight Bass! Im only running 400w rms on it in a sealed enclosure and my neighbors hate me. Can't wait for summer time in London! If you want to be that guy cruising with loud bass, then this is your tool to make it happen. WE LOVE BASS!

buy it definitely

Value is great. Quality is amazing. I am looking forward to buying another one.

Amazing subs, shakes your brain!

Truly amazing subs these type r's are. Use to have two 12" in my old car hooked up to a 1000 watt rms rockford amp in a ported enclosure and man did these subs slam! For sure the hardest hitting subs I have ever owned. Would recommend these to anyone looking to rattle their brains!

best in the game

I have 2 of these with a 3 cubic ft box and 2 Alpine mrx 1000 watt amps and these subs are the best in my town no one can match me and to any one that wants to buy kicker alpine is the way to go plus these things can take a beating.

great

These Subs are freaking awesome. I got one in my car and its so loud and clear. Recomend to anyone for the price and wattage. its hooked up to a jackhammer amp.

Good all around sub

I really like this product. It is loud and pretty crisp and I only have it on a 500 watt memphis amp. It does smoke a little when I turn it up but im pretty sure thats my very old amp, and not the sub at all. I didnt like how the bannana clips for bridging the voicecoils felt so I just used speakerwire. They were just very loose. I listen to hip hop, punk, rap, dubstep and it compliments them all very well. Oh and if youve never listened to dubstep on subs then dont hate on it just yet. Its totally different. It is really about the bass you just dont get on headphones. Lol

Danm

I am running 4 of these puppies in my ford with about 7000 watts. These subs are drop dead sexy with HQ bass. If you want bass that will shake the crap out of your can + 4 blocks away these are the cheapest subs to do so. BTW you dont need to let these subs warm up in the winter, even tho its still a good idea.

I need more juice!!

These things are beasts. If you can't afford the really expensive stuff go with these. They won't dissapoint you. I started with one of the older models and it pounded on my amp pretty nasty for a single 12". Kind of reminded me of my w6 in a way. Now I have the newer model to go with it. I have the Kicker 750.1 running them in a sealed box in a Camry and its not enough by far. It sounds like one still. I have everything wired to the lowest ohms I can get em. I wish I would've gotten the 2 ohm ones to give em a bit more power, but I can't complain. I think they would be better off with a slot ported box but they sound very clean the way they are. With the right amp and set up you can run just one of these and be happy.

WOOWWW

Holy crap i was at b*st b*y amd saw this and was like well ill give it a try and i shook my big mirror out of place on the drivers side but not only does it shake everything it delivers the bass that you need to hear!!

Alpine quality

This is the best overall sub for the money. I have 2 of them in a custom ported box that cost more than the subs! They are perfect for my pontiac g5 2009, but i also picked up a kinetic hc 1800 to help with the power issue and the dimming. LOVE THE NEW SIZE it saved space in my trunk! Oh and sonic does have the lowest price and free shipping!

more than enough

These can take a beating!

AWE-MAZING!!!

The title says it all! I've had this sub for a day now and I still am surprised that I have all this bass coming from a 10" sub! It hits the highs and nails the lows and fills my whole Subaru with quality bass without rattling the trunk annoyingly. I put this in the sonic sealed box with .75 cubic feet hooked up to my old MTX TN250 Terminator amp and this thing barely takes up any space back there. This sub will not disappoint you!

High output, Good sound quality

I wanted a sub with high output and good SQ at a low price, after doing a lot of research, I decided on this woofer. I tossed it into a 1 cubic foot sized sealed box as recommended by Alpine for SQ (I mainly listen to rock music). I juiced it with an RF bdCP 1000, 900 watts at 4ohm.

I used to own 2 RF 12's powered by the first model Bd1000. This single 12 hits at least 70% as hard and has better sound quality.

I bought one more of these, and I'm thinking of sending it back, a single one is so loud. ( I will probably keep the extra one and hook it up)

I havent tried wiring this sub at 2ohms (My amp gives 1500 Watts at 2ohms) But I would imagine it would probably sound even better.

This sub sounds good for rock and rap, but for some reason, it makes techno and dance music sound great. It feels just as bulletproof as it looks in the pictures.

Insane Bass

I have one in a 2009 Ford Escape for my wife. It's running off a pr2.100 Memphis 2 channel bridged at 300 rms. This sub is by far not getting enough wattage but the sound and clarity is superior than 2 PR Memphis 12's. This one sub is plenty for her car and I recommend this for all. This sub is well worth 200.00 range easily. I fiberglassed a box with 1.9 cu internal vented tuned at 32hz. This is a 5 star sub.

GET 2 of them

I got 2 of these hooked up in subaru STI and man do they shake the heck out of the car it feels like they are about to break apart the car

type r in probox

Great sub. The quality is great on this item, the first one I got was a dud but Sonic took care of me quickly. Thanks Sonic

Two SWR1243D on a BXI2607D at 1 ohm

These subs can get really loud they can almost handle all the power my bxi2607d puts out at one ohm but I cant run all the power to them.
I would recomend these to someone who likes mid low to mid bass they dont go too low so if your looking for low lows like 5-30 hz look somewhere else I put them in a box that is 3 cubes per chamber tuned at 32 hz and the aw1208t's I had in the same box really hit the lows crazy but these r's they are more for 30-60hz bass that most rap plays and they sound really great just don't hit vary low like i would like or Im used too lol

awsome for the price

I bought two for these subs in June and man do they sound good. Ive never had alpine. Ive had kicker cvrs solo baric cvx Ive also had memphis and to be honest with you nothing has compared to these other than I really liked the solo baric l5. I have the bxi 1610d running two of them in a ported box I dont know the cubic feet of the box lol but the bxi is rated at 1600 rms but ive talked to several at sonic and this amp pushes about 1400 rms but they do hit pretty hard I have 0/1 gauge ran and I upgraded my alternator to 150 amp and I soon will be getting the sk-bt60 and another sub! sonic is a great place to buy from ships fast I would recommend this sub to anyone for the amount of money sonic has them priced at you cant beat it.

Awesome Subs

I bought 2 of these. Threw them in custom 1.7cu Per ported box. Cant beat it. I have them in an escort. Got my windshield and my wipers shaking like crazy. I have them on an alpine MRP-M2000 and I am very satisfied.

GOOD BUT YOU NEED

You need the correct box for this sub to sound incredible. They hit hard. If not in the correct box the bass could sound harsh and not so clean but in the proper box the sub wont let you down.

Alpine SWR-1243D

Great subwoofer!

Great Subs!!!!

This sub is great. Very competitively priced! Performs very well, and can handle each and every of them 600 watts!!! Its amazing really. Probably gonna pick up another

Loud Sub

I listen to one of these all the time in my friend's car. It slams! He pushes it past the rms too often but this subwoofer handles it well. I have seen this sub pushed obviously past it's limits for a couple minutes straight and it is DURABLE! Luckily, it just wont blow. The sound quality isn't there. I have W3's and they are noticeably cleaner. If you put this in the right size ported box, it is well worth the money.

Great subs!

These subs are a great deal. They are built with amazing quality and they are cheaper than almost any sub in it's class. I have two of these with a Hifonics HFI2000d amp and they pound. Make sure you give them enough power though, otherwise they won't play at all.

Excelent Sub!!!!

This is an amazing sounding sub! Very good purchase. Once installed it hits hard and accuratly. Perfect for an easy, great sounding system, on a small budget. This thing makes some noise!

BANGERS

My brother owned two of these in a ported box being pushed by an Alpine MRP-1000 amp. i was getting a 5 star back massage in the front seat! he recently switched to CVX's but id say these subs are in the same class as those are. really a lot of bang for your buck.

awesome

i just put one in my 2004 cavalier last night and it bangs for sure. it was an upgrade from two 10" audiobahns and it hits just as hard straight out the box. i cant wait til its broke in so i can turn my amp up. i think im gona stick with alpine from now on. definitely recommend to anyone especially for the price.

Blew me away!

I just got finished hooking my 2 alpines up to a hifonics brutus amp at one ohm. Each are getting about 600w rms and they are brutal!!! Would highly recommend these subs to anyone who wants clarity with their hard hitting bass.

bad a**

I have 2 of these in my Mustang hooked to a 200 watt Alpine amp and all i can say is omg they shake my house and both of my neighbors

ridiculous loud

I would absolutely recommend the alpine type R. I have it hooked up to an 1800 w kenwood amp and it is ridiculously loud!

GREAT AMP

Bought this amp from SonicElectronix and man i gotta say it plays way better than i expected. The rms is really on point from the specs. I have eight pyle pro pdmr5 mid range on each channel and wired to 4 ohms its loud for just one door. Each door has eight midrange on it, spl competition, and i rewired it to 1.7 and it nearly trippled the output. My ears were ringing and the q-tune is really good, it adds depth to the mids giving them the slight echo vs raw boring highs. The sensitivity makes it really loud if turned up all the way but not neccesary. I recomend it to be used for any system. it is a really good amp. forgot to mention i did bridge the doors at one time n you wont be sorry you bought it. one recomendation is to upgrade your charging system with the big three and i added a second battery because of the low current my alt. puts out. 14.7@40amps 200 amp alt. coming soon so it can goo even louder. when i had the one door open , i had crnk it for a demonstration and the guys listening said their ears were ringing and stepped back. GREAT buy, never shut down on me.

Its alright.

I had my type-r 3 months and the cone came off the voice coil so I'm not very happy how Alpine built these. I spent full retail on the sub somewhere else.

Great subs for the price!

I have two of these subs, with each one being powered by one PDX-M6 Monoblock 600 watt amp. They sound amazing. Very clean, tight sound that I hadnt experienced with my past sound systems. You wont find a better subwoofer in this price range. Currently, I'm running 600 watts to a sub that runs at 600 rms, and it appears to be a perfect match in conjunction with the rest of my system, as I want a clean, blended and loud sound, not huge Boom Boom from the trunk and nothing else being heard. If you're like me, you read nearly every damn review before you punched in that credit card. Buy them!

Great Sub!!

Pushes great bass and with that 20% reduction i think it is a sub basically for anyone. i have one in a custom built box in my 1978 Ford F-150 ranger XLT and it has great sound quality and amazing bass. Alpine has a great product on there hands!

GREAT SUB!!

I bought this sub about a month ago and i love it! It hits so hard and im def buying another one!!!!!

Great Amp!

I have this amp powering 2 Boston Acoustics G5 1044 subs (10" dual voice coil) wired at 2 ohms for 500wts rms each.

This amp rocks. It makes my subs pound so hard. The day I installed them I had the gain set at 50% in the garage of my girlfriend's condo as I tuned the frequency. About a minute later she came down and told me I was shaking things in the kitchen 3 floors up!

The installation was very easy, and the adjustable sound level (RSL) knob makes it even easier to adjust on the fly as I change music types, ride with a passenger or pull into my neighborhood.

Only negative is the fan is a bit noisy. This is the first amp I've had with an internal fan so maybe comparatively it's not bad (and perhaps if it wasn't in an open hatch I wouldn't hear it)

Amazing Subwoofer

Previously, I had a 15" Kicker Comp, and I loved it but it was too big and took up too much trunk space, so this time around I wanted something smaller and louder. I got it! This is a great sub woofer and will not disappoint, I couldn't be more pleased.

Boston Acoustics GT-2300

Amazing amp. Makes my pioneer 100 watt rms sub pound.

Totally worth it!!

Use to own 2 of these bad boys and had them in a slot ported enclosure in my Delta 88... never regreted the purchase because they stood up to their reputation in both SQ and SPL.. I would probably still have these if they hadnt been stolen from my brother when I loaned em to him to sell after my car got trashed... they last, sound great, and can play all spectrums of music accurately and clearly!!!

Excellent sub!

I'm running one of these with the 600watt amp made for this sub, and it sounds excellent.. actually made some plastic clips in my car rattle loose causing plastic parts to detach lol. Great sub just give it proper time to break in, I blew a 1242D (previous years model) by pounding it too early in the break in process. Once its broken in, it can put out a lot of bass for a long time without overheating or anything weird like that.

bumps hard

i bought this sub a while ago but bought a truck so i never quite had enough room for all my stuff and a big 12" ported box so i sold it to my friend. he has this sub in his trunk and even with the seats up it still bumps hard. He has it in a ported box and it really sounds good. He has it on an alpine mrp-m500 and you can tell it makes the sub happy just by how clear and loud it gets.

great subs, can take all you throw at them

Awesome subs. I have two of these in my 06 explorer with only 600 watt Sony pushing them because my other amp broke. They are in a fiberglass enclosure custom tuned to 34 htz. The subs with the amp and 2 guage wire and Optima battery surprisingly do plenty of shaking for me and I don't need any more power.

A ton of power

After installing this beast in my car it occured to me I could use this for welding. I am however using it to power my 12" L7 woofer. The bass is incredible and what a improvement over my last amp. This amp is now going in my new ride with my A/D/S 6 channel.

Clean Amp

This is a very clean, well made amp. The features rock. It does run a little warm when cranked @ 2 ohms for a while but performs solid any ways. I have it pushing an SPG555 so I don't have to run it to the tilt to get it to hit. It's a little spendy but worth it. I'm glad I got it.

Alpine r 12

I have 3 Type Rs and they slam. There in a triple sealed box. Need to get another amp to power them. You can't go wrong with Alpine or Sonic.

Nice Upgrade =)

I just purchased 2 of these a few weeks back to replace my 2 kicker cvr's and there is clearly a noticeable difference in spl, these things pound hard! I have them in a ported box and the amount of air these things can push is almost ridiculous. I have them wired at one ohm running off a 1000 watt MB Quart amplifier which I also got from sonic and I am completely satisfied with my purchase. I would recommend these subs to anyone! Great spl and also great sq! Apline rules! =)

best bang for buck

I went head and got 2 of these with a hifonics brz1200 and did a custom ported box. box alone is big enough for 2 15s so for these 12s they HIT!!!! I have them in a chevy tahoe its flexing wipers, sunroof, side doors, and back hatch rattled so bad had to do 5 sheets of dynamat. overall get these they are crazy loud

Wow.

I bought these subs a couple of days ago and they BANG. My system is the loudest I have ever herd and I installed it for less than anyone I know with subs that are wayyy cheaper because of Sonic Electronix. And not to mention when I play rock and even old songs by the Beatles they add so much depth to the songs it's amazing. Like my studio speakers! 100% recommend these.

buy this and you'll be bumpin

My friend purchased this and i helped him install it into his mustang. he didn't want crazy bass so he got one. Not even broken in yet and its ridiculous for 1 sub. Sound quality is great and its still very loud. i would recommend this to people that want good deep quality bass.

Great investment

It's the most Valuable Thing That I could have ever given to myself . The sound's Weight and clarity are incomparably unsurpassable.

Great subs for the price

These things pound. I currently have a Kenwood eXcelon 794x running to these subs and make them absolutely crisp. I have a Hifonics Brutus 1200 RMS and let me tell it pushes the subs to the max and you cannot tell they are not slowing down one bit. For the price and quality I would highly recommend these subs to anyone who is looking for sum slap.

Serious Sub

I have this in a SonicElectronix slot ported box and wow does this put out some serious SPL's with 600 clean watts from an old Diamond Audio D5 600.1 amplifier wired in parallel. This combo sounds and feels like it's going to rattle my Civic Si Sedan to pieces. I am going to need some serious Dynamat to keep it all under control! I highly recommend this sub. There simply isn't anything better in this price range.

Some of the Best

I have two of these hooked up to an alpine MRP-M2000, getting about 750-800 watts rms each. They hit real hard. Mine are in a sealed box stuffed with polyfill. Get these and give them lots of power.

Good sub

Just installed one with an mrp-m500 and it hits good. Bought some more for me and accidentally spilled some epoxy on it. When getting the epoxy off, it peeled some of the cone with it which is when I noticed that the cone is not really "kevlar" but pressed paper with a metallic paint coat on top. Other than that, its a great sub...just wish alpine didn't twist the truth

Good Sub

This was the third sub I ever had and it sounded pretty good, I ran it at about 600 watts rms power and it hit the lows great. Definitely a good buy.

The Beast!

I bought this sub and made a downward facing sealed enclosure with about 1.25 cubic foot air space. Running a 2000 watt amp and it hits great! Good clarity, thump, and rugged build. It kills in my large truck. I wouldn't need another since it does what I need, but if I did I would definitely get another alpine.

Great Sub! Nuff said

I wanted a sub that could meek my quality standards of rock music but i also wanted to be able to beat the block down with some bass if i had to and this sub does exactly that! I have two of them in a ported box and the make my windshield have excursion! Do not take a second guess just get it and you will be happy! Trust me

great price, awesome sound

I purchased two Alpine Type R 12" subs and they really bump but most importantly, they have great sound quality and are very durable. I highly recommend them

Well not sure yet

I bought these to replace my kicker cvr 12s, thinking higher x max would allow them to hit deeper than the kickers.I put them in sealed boxes and run each one with a Kicker 750 amp. They dont sound as loud and are distorting when turned up.Might be bad amp match up or I need ported box? I have however heard one of these subs in someones car ported and it sounded great so that is probably the answer.

God Damn!

I have four of these in a sealed quad box hooked up to a single alpine mrp-m2000, thats 500 watts per subwoofer, an alpine head unit with monster 400 series wires, optima yellow top battery and a kinetik's hc600 and all i have to say is god damn in the words of e-40 "my s*** bangs" great subs this is the 3rd system that ive had 12" typr r's and ive never been disapointed. I had a single original 12" type r in my caviler with a directed 1100d blew it but thats bound to happen when you double the rms to your sub then i bought two of then next series same directed 1100d in the same car sold them for 15 kicker l5's "dump stupid idea!" now i have four of the current models 2011 little r's 100 more rms then the last two series so yeah i know what i'm talking about when i say buy these muthaf***** subs they take a beating and sound great and for a this price s*** you would have to be stupid to pass them up!

ALPINE SWR-1243D

I have recently bought 2 of these bad boys, and let me tell you. For the price and Quality they're a steal!

Nothing like ALPINE or SonicElectronix when it comes to audio equipment!

Awesome for the price

The new third generation Alpine Type R has some pretty nice changes from the last one, like a higher RMS rating to be the best change, a slightly more shallow mount design, and a better motor cooling system... But the bottom line is this thing pounds hard for such a good price.

awesome sub

i have one of these bad boys in my car hooked up to a 500 alpine mono block. this thing bangs. i have it in my jeep liberty in a 1.5 cubic foot ported box. all i have to say is wow!!!!!! i get out of my car sometimes with my ears hurting. i plan to get a second one and another amp to power it. one is perfectly good for your car, but if you want to get some nice comments from your friends get two. you will not go wrong.

It Rocks!

My kid has one in his car and i've got two in my boat. These speakers are tough, sound great & are reasonably priced.

Great sub

This is a great sounding sub and can a Lil more power than it is rated. have it wired @ 2 ohms n a ported box running off an alpine m500 amp. also tryed it on an alpine m650 n it handled it with ease. would recommend to any1 who loves tight clean bass

Awsome Sub Great Sound

Alpine Subs just rock, I have had Kicker CVR,CVX, and L7s, DD, Rockford, and JL W7s sure those are good subs great SPL so so sound quilty. For the price Alpine can't be beat nice SPL but also amazing sound quality ever at max volume, if you thank there not good it is prob your box you need to always have a custom box built for your car/suv for your subs to be the best they can, sure a prefab box works but the box makes night and day in quality. I have two in a custom 4 cf box ported around 30hz for SQ the higher the port the more SPL but the less SQ. There running off a clarion PDX11500 1500w RMS at 1 Ohm and its more then then Kicker L7 15" I just took out. Will always buy Alpine as long as they keep up the great work.

Quality Sub

Absolutely no complaints. I've had this sub for 6 months and it hits hard.

great sub...great sound!!! wouldnt expect anything else from alpine

this thing pounds...i had one hooked up to rockford fosgate 500 rms amp..and it rocked this sub to h***...it pounds the heck out of my car...1 is all you need. if your looking for ridiculous bass get yourself a couple of these..you can run them on 2ohm at 500+rms and this things takes it like a champ

Omg omg

Best fricken thing I ever ordered in my life. With an unmatched price per quality level

Great amp!!! Best sounding amp ever!!!!

Excellent sound quality, great design, superb power! Can't go wrong with this amplifier guaranteed!
Boston acoustics did miss on putting an RCA output for linking to other sources. You would need something like that for expandability.
Overall the amp is a 10 plus.

great woofer

This is a great sub i got a alpine mrp-500 mono amp pushing it and it thumps really hard, great value for the money.

Can't go wrong!

Awesome power, nice look, good fan which is also not too loud. Worth every penny. Don't know reliability since they're new so i've put 3 stars.

Free amp kit

The amp I bought came with free amp wiring kit. Awesome saved me money !!!

Got the package fast. These pound in my car. Didn't realize how hard they would hit. I am very satisfied for the price i got them for. Also came with really thick wires. So far they been fine and I've been blasting them down the street and people can always hear me.

Cost effective

This is a good cost effective amp wiring kit. Happy with thus purchase!

Missing speaker wire, the one shows on picture

Good value but remote wire sucks

Good thick flexible cables. Only complaints are rca’s are kinda thin and remote wire is very thin too, ground and power cables and fuse works good!
