works great

Hooked it up with an re audio srx 12 and it sounds great very very happy.

decent box

i bought this box for the newest alpine type r.... lets say it sounded decent but not good enough for me, i have had many sound systems and this didnt sound so good with the type r..... if your decide to get a type r id go with a 3.0 cu ft box tuned 32-38hrtz for the best deep loud sound quality

Great Solid Box

This box is built very well. It's perfectly tuned for the Alpine SWR-1243D Type-R that I also got from Sonic Electronix. The SPL of this combo is ridiculous in the trunk of my '09 Civic Si Sedan, and it leaves more than 3/4" of my trunk space left for other junk. Definitely recommend. With a set of banana plugs also ordered, I still only spent less than $225 which includes the price of shipping for these three items. Speaking of which, I ordered in the early hours of Tuesday (switching over from Monday) and I got the these three items delivered to my door by 11AM Wednesday! There's no way you can find a better deal than that! Now all I need for this combo is some serious Dynamat to keep everything from rattling apart.

Great Box!

This is a nice box for the price. I normally build my own boxes but I didn't have much extra time and it is too cold out to build one anyways, so I bought this one and I'm sure glad I did. Realistically to buy a sheet of MDF, spray adhesive, bottle of wood glue, nails, and carpet costs about the same as this box and it is already made. Sure it is prefab, but its a very good prefab enclosure. This is real 3/4 inch mdf and the port is tuned pretty low too. I would guess like 34-36 Hz or so. Very solid construction and rounded off port on the inside. Carpet looks great. Terminals are nice too, although they are plastic fasteners, they will hold up just fine. I have a Phoenix Gold rsdc in this box and it slams! I can feel the bass pounding my chest. If you want a nice loud box, this is the box you want. Exceeded my expectations by far!

Not correct box volume

The box is advertised to have 1.8 cubic feet of volume. It's not, the actual volume when taking into the account of the wood thickness and the ports is 1.3 cubic foot. Plus when you add a sub in it that will also take up some volume so you can count on 1.1-1.25 cubic feet with a sub mounted. The 1.8 cubic foot might be true if their talking about total volume of the outside but that is compleatly irrelevant. The only volume that is important is the inside of the box. And yes the difference between 1.8 and 1.3 is a lot and will make a difference

Belva

I have 2 of these in my car but they do the job with Type-R's no complaints

Bela Sub Box 1st 12 box

The box is built great, sturdy. I didn't pay attention to the overall dimensions the box is bigger than your average 12" box.
So if your looking to put this box in your car make sure you pay attention to the dimensions. But if your building a subwoofer for home or small club this box will do the job.

awesome subwoofer box

This subwoofer box is great and produces a lot of loud bass. However it is huge so make sure you have enough room.

A+ product

Fast Fast shipping. For all you guys that are looking for a clean box with great value and durability this it. I'm using it to support my 12" Olympus Series Dual 2 ohms Subwoofer (OLM-1612). Buy it !!!!!!!

Sick box.

It's pretty massive. Carpet matched my trunk which is a win. Screw terminals are not the best but they work.

great box

I bought this belva 12in box last month and put a 12 in kicker comp r in it whick I'm putting 800 watts rms to it and it sounds great. This box is also listed at a great price.

well built

this is a very solid, well built box. the box is sealed well at all seams also and made of good quality mdf. I have a kicker cvr in it and it sounds great. great choice for a single ported enclosure. can\'t go wrong. by the way, i think it has great binding posts. good value, it won\'t disappoint.

Nice product

This box is a very nice box especially for the money. Gives a crisp clean sound and doesnt matter what type of music you are listening to.

Great box

I put an Audiobahn Alum12X in it with a 200 watt RMS amp. I had to widen the hole a little to get it to fit. It is nice and loud. I put it in the back of my Honda Element so the port fires under the rear seat toward the driver seat. For the cost it cant be beat. It would have taken me hours to put one together. What a time saver. This is the first box I have ever purchased. I usually just make my own.

decent sub box

Bought this box for my son and put a sony 12 and visonic amp and it hits pretty hard and very loud but not as tight as the sealed box he had so he loves it because he's a teenager !

Solid well built box.

This box is great. ! I have a Power Acoustik GW3-12 in this box and it really pushes some air! All my mirrors are blurry while im driving nice clean bass

great

hooked it up to re audio srx 12 and it sounds great

Sounds great

This box sounds great with my alpine 12. The terminals were easy and the box is put together well.

Good Box for Cheap

I needed a box for a C2 Audio Threatcon 4 subwoofer. C2 cuggests a box near 2 cubic feet tuned to 35 hz. This one is tuned to 36 as a I recall so it's pretty close. It's nicely constructed. Wish that it were slanted so that I could put it up against the rear seat of my car and that it were tuned a bit lower. For 35 bucks I couldn't build it for less.

great buy

my brother bought this for his kenwood 12. it sounds like he has 2 12s. the crazy thing is he is only pushin 220watts rms. box makes all the sound. get this if you need a great box

Great

I bought this box for my Rockford P3. The box takes up half of my trunk but it slams my sub. You can't find a better deal on a ported box like this anywhere

works great

this box works and sounds great if your sub calls for the air space buy it

Belva sub box

I have owned this subwoofer box for 30 days now and it sounds great and looks great. The porting on the box makes it sound even better. And is the best box for the money

Outstanding quality & Price

Would recommend, sturdy construction with insulation.
Improved bass quality, w/new box I could hear bass notes that were missing before.

Bad.

I bought this box a while back and one of the speaker wire terminals is loose causing the connection to be weak.. its been loose since I got it but it just recently started causing problems.

pleased

I bought this to go with my orion xtr pro. it makes the deeps better mids louder and highs annoying. Make sure if you buy this product to tighten the connectors a little more. i put my system together but damn near broke one of the connectors when tightening by hand. Other than that i am very pleased with this product. Sonic Electronix never fails me! I recieved it in three days from KY to WI!

1SV12

I bought this box for an Alpine Type R 12. I usually build all my own ported boxes but I decided to save some time and buy this one. The box is built from quality 3/4" MDF, the carpet looks great, and the seams are well caulked. What you really should know when buying this box, it is around 1.5 cubic feet net, and tuned to around 35hz. A little small for most 12's in vented applications, but the 35hz tuning was a pleasant surprise. Most prefab boxes I've seen are tuned >40hz and can't quite hit the low notes. Overall, definitely a great value and a decent design.

Not to bad but could be bigger

Got this box to house a American bass xfl 12". I needed a bigger box but I have a small trunk so my options are limited. my 12" beats in this box just not at full potential. good box for pre-fab

great box

This box is great and you wont find such a nice one at this price anywhere.

single 12 inch vent ported box

Bought this box a while back and must say for the price its a great box. Ive looked at other higher end box's and they are way over priced. Good construction and seems sturdy. I would recommend this box to anyone who wants a single sub system.

works well

works well with my alpine 12". installed the sub into it myself, very easy. good value. go sonic!

great box great price

u will never find a better ported box for this cheap. it is very well built. sadly it is currently serving as a nightstand in my bedroom due to the sub no longer living there lol

Great Speaker Box

Makes a big difference in the bass. This box is good for a smaller type of trunk.

Awesome box

Looks attractive, feels sturdy, wasnt expensive. Perfect for my memphis 12. I actually ended up with the exact box except black.. so i assume the picture is wrong, although i'd rather a black box anyway.

great box for the price

It sounds great. and looks nice. fits well in my trunk also

Worked well

Was used for mtx 9512-44 worked well for what I needed it for...

Awesome

Great sub box, looks good. Its heavy, heavier than i expected. Lined with the poly fiber stuff as well

Strong Box !!!

A well made , strong, & nice looking box .Being glued then screwed is the only way for a sub box, to be made , with the vibbrations it must enduere ,this one pass the test .I have recomended them .

not the best for a type r

its pretty loud but tends to sound kind of sloppy at some notes. if your new in the audio game i would get it but i wouldnt recommend it. if you want to save a little money id go with a sealed 1.0. on the other hand if you want crazy loudness id go with a building your own ported box or you can find a good prefab tuned at 32-38 hz. but im happy with it but soon to change box.

box

this is a great box, great build quality. great port flow and absolutely no port noise. great box

Great buy!

Matched the air space to my boston g2 12'' sub have no complaints at all
sturdy, clean !

Great value

Ive had this box for a good 6 months and havent had any problems. Very durable and built right. Im running an RE 12 and an RE amp in a tahoe and this thing slams! It would be hard to build one for this price. Only complaint i have is that it stinks like they heat treated the mdf or something. My truck smelled like a forest fire for a good month or two.

Sub Box

Great box! Excellent quality, especially for the price. Have had it for 6 months now and it looks like new. Very impressed for how cheap the price was!

Great Box

The works perfect. The box is more durable than i thought it was going to be. Just the right size that i needed. I even put some poly-fil inside to enhance the sound of the subwoofer. Great price for a great box!!

Great so far!

Bought it six months ago to house an Adire Brahma 12" (old-school). I needed 3/4" MDF and around 2sq.ft., ported... Even with shipping it was about half the price of buying a similar box locally, because all my local shops are rip-offs...Sonic can't be beat for price!

So far, everything is great! Only thing that's failing is the window trim on my Pathfinder. X)

One hell of an upgrade

went from sealed .8 cubic foot box to this ported box for more volume. the difference was night and day. i have scaled back the gain on my amp and dropped the sub volume to 0 on my deck, and this box still provides so much volume i'm afraid the back glass will fall out. simply unbelievable. fyi, alpine type x and hifonics bxi1606d, 1100w rms @ 2 ohm.

THE BEST

This box is the best if you want a ported box. It just has everything you need for a well cheap price but the box is just amazing. I put my kicker cvr 12 and that thing bumps, am definitely buying another of the same box for my other kicker.

Okay enclosure

I bought this box because it was a lot bigger than the previous box I was using. I have a Pioneer Premier TSW3001-D2 in this box and it still needs more than 1.8 cu ft to show its true potential. Overall its a good box and it does have good sound quality, but I am not hitting any of those low notes with it that I really want.

Great box for a prefab

I have a RE Audio SXX 10” in it. Sounds great in the box tight and clear. Bo is tuned to 36hz. Great box.

great box

nice well built. only thing it lacks is being pre wired. so you might have to spend a few bucks on connectors. but it is nice. buy it

im running a dvc 12inch pioneer champion series off a fli acid amp its 600watt rms 2ohm mono... bumps

Great value!

This is a great well built box. I have an RE12" sub in it and it produces the sound that I wanted. Great box recomend to all!

nice box for good price

product is durable, produces good sound and is a very good deal

great box!

When I got the box, it was broken at the face plate by the port. It was in the bottom corner. It wasn't too bad so I decided to drop the sub in anyways.
I have an nvx sub in it and it sounds really good. The lows are deep.
Overall it's a good quality box and sounds great

good box

This box does what it says. Make sure to use the right screws as this is soft wood and will strip out.

Solid box for the price!

This is a good solid box for its value, very study and looks decently sharp. obviously there are better boxes out there, but for this price you cant as for much more. i'd recommend it to anyone trying to build a system with out big spending. great product, thanks to sonic for low prices and super fast shipping as always

Box works great.

Nice ported box. Helps get those deep tones. Very happy with the product.

Great little box !!

Kinda small but just big enough a “12 sub to get loud ... Good Buy!!

Nice enclosure.

Bought this box and put a Pioneer Champion pro series 12" in it. Only pushing about 400 watts to the 600 watt Pioneer, but sounds nice and clean. Hits the low notes well. I really like the durable gray carpet, (doesn't tear and get dirty as fast as other black boxes I've had in the past). Box is well built and I like that it has pre-filled walls inside.

Great product

Very nice fabricated box, great sound quality highly recommend this enclosure

awesome box

I have a cerwin Vega vmax that I've had in a homemade sealed box for years. It sounded great or so I thought. So I bought this box because I wanted my sub to get louder and wow what a difference. I could not believe what it did for my sub. I didn't change a thing but the box and it slams so hard u can feel it in your body. Could not be happier with this box. Appears to be good quality, mine came with a metal belva name badge at top left of box. They even painted the inside of the port black. Long story short lol, get this box.

FORGET THE RE SUBS

I've used this same sub box for 4 different brands of subwoofers and they all fit perfectly. This is a GREAT prefab box UNLESS you're wanting to use an RE sub. I bought this box with the RE Sxx and the basket is bigger than the opening of the box, so it won't work without modifications. And the only reason to buy a prefab box is not having to go through the hassle of making modifications. So it's a GREAT box, will be the best prefab you'll find for this price, just DON'T buy it if you're wanting to use an RE subwoofer.

Nice Box.

Well built box. I like the durable black carpet lining. Holds up well and doesn't tear easily like other boxes I've had. Check how much room you have in your trunk because it has a good amount of cubic space. I still have plenty of room in my 07 Honda Accord. Love that it's pre-filled. Have a pioneer 12" champion series sub inside and pairs up nicely with this box. Sounds clean and the lows hit nice.

By Joey on September 27, 2015 Verified purchase

Great product

This product works great. Sound quality is definitely good, and I would definitely recommend this for anyone who's looking for a ported box.

Love it!

Bought the sub box about a month ago and it was easy to install, no problem with my 12" sub. Looks beautiful and professional and my sub sounds great and non-distorted.

Decent box

Id revomend this box for anyone that doesnt need a custom box

Good price and well made

I was looking to down grade to a single 12” and this box was a perfect purchase for what I needed with still having space in my trunk for other items.

Very nice budget enclosure

Been running an Alpine tye R in a sealed box for a while and have been OK with it. I have tried this 12 in a couple of other prefab vented boxes and sound quality was terrible. One box was similar in size to this but was tuned way too high and was nothing but boom. The other box was much bigger and tuned to around 32 hertz and was a little better but had absolutely no upper bass and an overly pronounced low bass impact.(very uneven response even after much time spent on setting adjustments) With only a day of listening to this particular enclosure, I have to say it's much more musical and really surprised me. It's blending with my components much better and has the advantage over the sealed box of digging into the very low bass with more authority. I'm hesitant at this time to say it's actually sounding "better" than the sealed box but at this price point you can't go wrong here. Construction is good overall and my box had no cosmetic flaws at all. My recommendation is, if you want a relatively smooth sounding vented enclosure that won't break the bank and looks real nice then this one's for you. Really, at this price point it's a steal and I highly recommend.

Quality > price, must buy!

I bought this for my nephews new civic. He has a kicker CVX that requires 1.8-2.5 cu ft of airspace. I purchased it through sonixelectronics eBay page for 44 w free shipping. Pairs with the sub and matching 300w kicker amp it produces 42hz of clean clear bass. The beauty of ported boxes is that you can get clean low punchy bass with minimal wattage (assuming you make sure your speaker is wired correctly so the resistance matches what your amp can push efficiently). Look up the wiring diagram for your speaker and amp then match the lowest stable ohm possible. Matching the ohms resistance is more important than just getting the most wattage and your system will last longer and endure less stress. Ok now back to the box. It comes carpeted in either black or dark grey and comes with a nice layer of insulation inside which helps produce the low clear bass and the knock behind it. It also comes with a removable manufacturer tag if you don't like the look. The box has really nice terminals that accept banana plugs which I highly recommend, not only do they look nice they make the connections easier. Overall the quality and value of this box far outweighs the cost. I really couldn't get over how nice it was for the price and when I install systems where only one speaker is involved I am now recommending this box if they do not want or cannot afford a custom box. You won't be disappointed with this box, & for any reason you don't like it send it right back to them.

Good box, was looking for something tuned a little lower.

Well built box for the coin. I did cut out the polyfil just so the port was clear, but left the rest in. It's got a good universal sound and is a lot more pronounced than the sealed box I had before. I have a 12" NVX VCW dual 4 ohm, bridged down to 2 ohm running a Hifonics Brutus 1000.1D
At max I am getting 700 watts RMS, but probably less. The sub is broken in properly and sounds great in the box, but would hit harder with another 300-500 watts RMS. I have my subsonic filter set to about 25HZ. I think the sub plays a little lower than the box is tuned for, not sure, but I think the lows could be better if the box was tuned lower for the particular sub I picked.. NVX tech recommended 2.25 cu. ft. @ 30 HZ. I will be building a new box when I can and tune it closer to 30HZ with a bigger amp. Like I said, this gets me by fine and I have no complaints!

Solid box

The box is solid and good quality plus it came with polyfil. The carpet on the box was peeling around the port though. Wasn't enough to me to send it back but still.

Sounds great

I was skeptical at first for I was going to go with the box made by Rockford for my P3 12'' but decided to go with Belva to save a few extra bucks and man I am happy I did. Its not to big and looks great aswell as sounds amazing for my Rockford P3.
Would recommend to anyone interested in this product!

By Travis on February 24, 2016 Verified purchase

great value

This is an awesome box. I have 2 of them holding my twelves. Very loud deep bass. Would definitely buy again.

Decent budget box

I put a 12" Alpine Type R in this box. The carpet near the port needed a little extra glue to properly hold it down but not a huge problem. The R definitely likes it. Gets nice and loud and the box doesn't have any funny rattles or noises. The tuning is pretty good. Would prefer 34-35hz.

good box for the money

dropped in an old rockford hx2 12con 800w and it booms good after amp and crossover adjustments.

Good box true to size, adds lots of bass for the woofer

Nice box

I have had this box for about a month now. I am very pleased with it. I have an Orion XTR Pro 122 in it and it's very low notes. I have no complaints

The best

This boc is the best i have gotten in long time from 100w to 50000w .. This thing does it all..looks size design the best tbing about it is the sounds it put out ..good job

It's a box

works very well with the alpine type-s 12. The only problem I had was the metal plate on the front rattling but it just two screws to remove and the problem was solved

I'm amazed

I purchased this box for my friend. He has a 1st Generation Alpine Type R 12" subwoofer on 300 watts and his system honestly scared me because it was that loud. He seemed very happy when I got this for his birthday, and it makes me happy too. Very fast shipping and easy to install. Loved the cotton inside the box as it helps up the cubic feet inside for the sub to operate in. 5 stars.

By Brendan on July 13, 2017 Verified purchase

Great Box

Put a 500 watt sub in this box and wow. It sounded so good playing at any volume. The box is sturdy and good quality. The sub did match up with the box. The polyfill inside the box makes a big differance also.If you have a 12 and need this size cu ft air space box this one will not disappoint.

Best Subwoofer Ever built!

This Belva sub box is extremely LOUD!!! If you need that solid bottom hard bass for your vehicle, then I highly recommend BELVA SUB BOX!!!!!

By Odi O on May 18, 2020 Verified purchase

Best bang for your buck!!

This box made my Type R 12 pound harder than my last box! Just an FYI It’s slight bigger and wider from the other 12in boxes. But it is definitely worth your money!!!

Very Good!

I bought this because a customized box for my Skas vvx 12 was too much. his song great and I feel this is the best option other than customized boxes.

Awesome Prefab Enclosure

This enclosure is made extremely well. It made my NVX VSW124 sound amazing. It looks nice and will turn any subwoofer install into a professional looking setup. I’d buy this or another Belva enclosure and non enclosed subwoofers over a powered or non powered pre-made setup any time. Buy you sub, an amp that meets your subwoofer’s RMS, and the appropriate Belva enclosure, and be amazed. Amazed at not just the sound, but how much you saved over a pre-made setup.

By Matthew on November 19, 2017 Verified purchase

Free shipping, what????

This is a killer buy with free shipping. I used an Infinity 1260W woofer in this and it cranks with only a 200w amp. Place the woofer facing backwards in the trunk and near the back for best bass.

Great box!

Fosgate sub sounds awesome in this box. Nice quality and price.

Works good what I need good price great service great quality

Very good quality sub box

Very good bow made with quality materials. The sound is amazing...

Great box for the price

Great box, sounds good and well built/sturdy. Only negative is that it smells really bad.

Box

The ported box was a good buy. Very convenient with heavy bass.

Satisfied

I bought this sub because of the price. I blew my last sub and wanted a quick replacement for my budget build I'm doing. I've got just one of these and I've got 650 watts RMS running to it and I was actually quite surprised on the sound. You won't be shaking your door panels or trunk off but for what you pay, its worth it. Note that I've got this running in a 94 Corolla.

If you're looking to be heard from a block away or to show off, you'll probably want to buy something else, but if you're looking for something cheap that will produce some decent bass that you can 'hear' and feel a little bit, then I recommend this.

PS I reviewed this the day I got them and installed them. I cant say anything on durability yet but I'm hoping they last.

Solid construction and good sound

Installed a Rockford Fosgate Prime 12" sub-sounds pretty good...Definitely good for someone looking to add some punch to a mild system.

Good Sub

I would definately decommend this sub for any application. I am running it on a tiny amp my friend is letting me borrow for the moment (120 watts) and i was thinking it would be maybe as loud as the little 8 incher i had previously had in my car. I was mistaken. It is louder than some of my friends cars, and is running on almost a twelfth of the power it can handle. I am very happy with this sub. I had to replace my rearview mirror because it was shaking too much.

Good bang for your buck!

I purchased these subwoofers and they perform excellently! Awesome price, too!

Excellent value

I highly recommend the Boss CX122 sub. I got a great deal, and was very surprised at the level of performance for the price. It sounds better than a sub that I purchased a few years ago for 3 times the price.

ok

Product was installed into a bandpass enclosure. I don't recommend doing that. Specs said its ok but didnt perform to my expectations. Would like to have tried it in a different enclosure. It may have preformed better.

Great value

Buy its wonderful

Buy!!!!!!! There Awsome

I Bought 2 of these subwoofers and ive got them paralleled on a boss ce-1250 1250 watt amp i bought on here! Let me tell you!!! They pound the crap out of my 96 ford escort lx. My uncle which lives about a block away says he can hear me clear as day in his house!! I would definitely buy more of these!!!

Great Value!

I bought this sub for a temporary because of the price. I had two Rockford Fosgates 2000watt units, one blew. I put this Boss sub in and its hitting harder than the one fosgate that's left.

Not bad

Not the greatest sub in the world but also not the worst. I got one of these in a ported box being powered by a good Alpine amp. It hits pretty hard but you wont be shaking peoples houses riding down the street. Honestly for the price I can't really complain its a good sub if your just looking to add a little bump in your ride without spending a fortune.

Great Buy!

This product is very cheap but it put out major bass! If you want a setup with 2 or more subs then i highly reccomend this sub!

Great Value.

This speaker is really great, I have one 12inch BOSS Chaos Sub paired with a BOSS RIP 495 Amplifier , I would highly recommend these speakers. This review is after a full 30 days of use.

Beating down your block

Great sub. All my friends like it, and you can hear me coming a block away.

good buy!

This is not the loudest sub I have ever heard but it produces a good amout of bass! For the price I would definitely recommend this! I have 2 of these hooked up to a 1500 watt mono block SSL amp and it hurts some of my friends ears and others say it is loud. My girlfriend heard me comin from over a block away while she was inside her house! Great sub for price!

Great Value

Boss CX122 has been a wonder to have & still is to this day. I'm happy with the product.

Bosscx122

This is a great speaker I would recommend it to anybody.

Great BUY!

I thought these subs were weak but to my suprise they beat hard and take a lot of punishmet. Would reccomend to anyone looking for great sound.

Nice bang for the buck

Got 2 12s in my truck they hit and hard sound nice

Hit Hard

I recommend these boss subwoofers. They are a great value and they really hit hard when paired with a good amp.

Bang for your buck

For the price you pay, this sub is good. I have a Hifonics amp wired at 4 ohms that puts out 650 RMS and this sub can handle it.

Great box

I put my P3D412 in this. Had it sealed.

My word yall it sings ported in this little box. I will never go back to sealed. I was a sealed fanboy for 20 years.
The p3 sounds great in this box.

Love this Sub

Bought this sub 2 years ago along with a 1000 watt Rms monoblock amp in a custom made ported box in my 97 eagle talon and you can hear me down the street coming. All my friends are surprised and calls it the "magic" sub bc they think its 2 15s =D

Love these!

Great speakers, they look great and sound great! Gonna have to buy a bigger amp!

Great subs!

Don't require a lot of airspace and they hit really hard. Great product for the price.

good sub while it lasted :)

This is a loud subwoofer but dont last long. I had 4 12's hooked up to a rockford fosgate t1500bdcp which is really 1937 rms on the birth sheet, at only half gain in a custom fiberglass box in the back of my navigator and they were hittin hard. Too bad they only lasted 4 days. Thats what i was expecting anyways i knew they were gonna blow but just wanted to see how long they would last and yea it was not much haha way overrated sub.

BOSS CX122

This product Sounds real good to me I have mine running off an 1000watt AutoTek Amp for the time being. I 've had plenty of people askin me do i have two 15's all the time... I would Recommend this product its worth the try You will enjoy it

cx122

I own a regular cab short bed truck and bought this because i wanted a 12 that wasnt too big to mount behind my seat. i have it in a test box on my seat right now for break in procedure and dam does it sound good. right now im runnin a pioneer 820 watt amp to it bridged and the amp is about halfway up. It pounds! building a custom box for two of these subs and a amp from here too very great buy. thanks Sonix!

Good for the money

This sub is good for the price, but surely doesn't compete with the more expensive subs. This sub isn't as good as my previous Orion XtrPro 1000W 4Ohm sub, but it does have excellent sound for the money. If you're on a budget, this is a good deal. It looks nice at a glance, but the feeling of it is cheap.

AWSOME!!!!!

I definitely would recommend this sub. Got it in the mail today unwrapped it had everything that goes with it, looks great, sounds awsome, i definatly dont regret buying this. I got another one commin in the mail pretty soon.

boss

i wasnt really happy with this sub it puts ou a little bass it's only for my center concole and i got 4 12's behind my colsole and i dont know just doesnt really do anythang it's good if your wantin a little bump but not if your lookin to show off

bangin for 160 bucks

I ordered one of these and a cheap set of sealed boxes off eBay. After installing this sub, I instantly wanted to put another in the spare box I had. 2 subs for 70 bucks, 2 boxes for 35 bucks, and an autotek 1400 for 55 bucks. Let me tell you, I shook the whole truck. No flex, but shake, and they boomed. Took all the power from the ata 1400, wired to 2 ohms. Don't get me wrong these aren't by any means competition subs, but if you just wanna bang for cheap, buy 4 and you won't be disappointed. I had them in .88 cubic foot boxes, sealed, that's way under recommended airspace, go ported and optimum with the box dimensions and you will be golden for a beginner's setup. Be careful, they will blow, I blew one with my Rockville rxd m4, of course that overpowers them, and they actually took it for days, but then blew. Just follow the specs!! For 35 dollars I'm beyond impressed

Great Subwoofer

I got 2 of these in a ported box in my 1999 Silverado 1500 with a ssl 5000 watt class D amp and they pound so hard you can feel it in your chest love it for the price great product.

Best bang for your buck by far!!

I was skeptical at first about purchasing this sub, due to its brand and pricing. Boy was I wrong and I'm glad I was. It's not a performance sub by any stretch of the imagination. This thing can hit and it's perfect actually. Especially if you're just wanting some extra bass in your car. I have a 1,200 watt amp hooked up to this speaker on a mono bridged set up. That way I'm getting atleast a full 400/500watts going to this one speaker. I've experienced no clipping whatsoever. After about a 2 wk breaking in period (which is crucial, if you want it to last), I turned the amp up just a little to around 600watts RMS. Now this little speaker packs one hell of a punch! Im only using one of these and it sounds so good. I have it sitting in my backseat, instead of the trunk. I was surprised in the quality of bass too. It's definitely not a kicker, Skar, or any other high end speaker. But it sounds on par to one easily. In fact the regular person wouldn't even be able to distinguish between them. If I had two of these it would easily beat the hell out of my car. Personally it's just right, you absolutely can't beat the price for what it's worth. Im highly impressed with Boss and this subwoofer period. I definitely recommend getting this, you can't go wrong for the money. Essentially you have nothing to loose, think I paid less than $50 for this sub plus the box! Unless you're an audiophile snob and have to have name brand. Then definitely get these, I've heard subs that cost double the price as this sub. That sounded worse than these do and that's the truth. I'd give these easily an 8 out of 10! They honestly remind me of these Kickers I had back in the day. Boss has really stepped their game up, so if you're on a budget. Or just want a decent system that will bump for a fraction of the price you'll pay everywhere else. Then consider getting these exact subs Boss CX-122. Oh and it has a decent 3 yr extended warranty as well. So if they crap out on you, the you'll get another for free! You can't beat that, and they would only break if you don't know wth you're doing. Basically just because it says they are 1400watts. Doesn't mean it can handle 1400watts, you divide this by 2 so 700watts is the RMS. Do not surpass that amount. The perfect setup is sending it 500-600watts consistently. That way if it peaks it won't exceed anything over 700-800 watts. Otherwise you'll risk clipping it and destroying a perfectly decent sub. Remember these aren't for competition, just for casual bass in your car. They sound great for the price and for that you can't beat them. You won't be able to find another sub this good for the price, that's for damn sure!

Great value

I recommend this item, mostly for a serious music lover and serious bass head.

Awsome

Great product for the price. No issues ordering,can't beat it. Trust me.

Excellent for the price.

I combined two of these with a crunch 2000watt amp and my wife couldn’t be happier. It definitely does the trick in her Silverado. Would highly recommend!!

Boss CX122

Its okay. I expected a little more for the money.

Great box for the price.

This box is perfectly spec’d for a lot of great subs and it’s built very well for the price point. If I need more pre fab boxes, this will be the one

Great subwoofer box, Great box for JL 12W7. 1.8 CU FT, 36 HZ.

Great subwoofer box, Great box for JL 12W7. 1.8 CU FT, 36 HZ. I got this a enexspensive subwoofer enclosure for a JL AUDIO 12W7 sub, until I can build a custom one, it was the exact air space and recomended tuning, it worked out great, Ijust added a baffle ring to get a perfect fit on the sub mounting hole. The carpet could have used better glue, but at $70, it's a amazing deal. And great quality box, I would buy another anyday.

Good build quality and Value

This box chnged the whole tone of my car. I have a kicker compr dual 4 in this box and sounds so much better than a sealed box. I think it's now louder on same power

Beyond impressed!

I have a Rockville W6 12" sub. I had it in a sealed box and it was loud, I have never had a ported/vented box and wanted to see how my sub would sound in it. I cant believe how much louder and clearer my sub is in this box! I would not hesitate to recommend this box to anyone who is looking for great quality and performance! Absolutely amazing!!
