OK wire if you like red wire

I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

High Quality Box!

I use this box for my Rockford Fosgate 10 and it sounds amazing in my hatch. Connectors felt solid, box felt solid. 100% recommend this!

Great box for the $.

Dropped a RF prime In and sounds great. Well built. Great value.

Great Value!

Sturdy, fits like a glove not too big, not too small either. Can't make it for the amount they sell it.

FREE box...

Box is well built, its hard to mess up building a small sealed box.. The only problem was sub opening wasn't large enough for my sub, 5 minutes with a jigsaw and vacumn took care of that though..

Decent Small Box

For the money it is a pretty good product. The carpet is a nice black. Very dark and very clean. The box is solid and can take a beating. The terminal cup is nice as its a binding post and not those crappy pressure tabs. Good box, decent sealing, good carpet.

well built for price

i have a dvc pioneer 10" sub that fits perfectly in this box and sounds great. looks good in trunk and still gives me room to put stuff in it

nice sound

very good product at a pretty good price lowest i could find on net and sounds good

Nice enclosure

Not much can really be said about a sub enclosure, other than it does its job well. My Rockford Fosgate P1S2-10 fit in snuggly. The only thing that was a tad iffy was that when drilling once the bit went through it would catch of the inside insulation and mess it up, but quite honestly it didn't really bother me at all. Good enclosure.

Quality at a great price

I got this box for an Earthquake dbxi10 and thankfully the sub fit right in despite me thinking the measurements for the cutout were a bit off. The little bit of polyfill lining is a nice touch. The box felt secure and solid with a good bit of weight for the quality of wood. It definitely didn't feel like a cheap particle board box. The carpeting was on snug and looked good as well. Great pre-fab box for your sub. I expect it to last but can't say for sure as I just got it in recently.

Best boxes on the internet

great constructed boxes...great price...def recommend

Great Product!!!!

I totally recommend this product, excellent value! super fast shipping

Durable little guy!

Great little box if your not trying to lose your whole trunk!

Good build quality; can't go wrong with Sonic products.

Good Purchase!

This product is cheap, but is worth much more than the purchase price! It's built just as if I purchased a sub box worth 3 times as much! It was really easy to screw in the screws for my Alpine sub.

Great Box!

I used this with an Alpine Type R 10" and I had perfect tight bass, well balanced with speakers!

Great value...at least it used to be.

It is square and holds my Infinity sub. Is great and I have no complaints. I bought this awhile ago for $19.99, which is about as much as a wood box should be worth.

Great SQ box

This box plus a Phoenix Gold RSDC102 subwoofer makes the ultimate sound quality sub setup at any price level. Phoenix Gold really outdid themselves with the RSDC subs and this box is the PERFECT compliment to their awesomeness. It's VERY well built and looks pretty good too.

As a plus, it was physically smaller than I expected, allowing me to place it in several different areas of my hatch to experiment where the best quality sound is.

No need to spend more on boxes ... when you get best for so cheap :-)

I have 2 of these boxes in each of my cars. Box is awesome for my Alpine Subs. I totally recommend them to all my friends.

Good 10" sub box

The box is a solid sub box and has worked great for the past few months. No rattling and it is sealed well.

When paired with a high quality sub, this makes the perfect setup and allows you to keep as much trunk space as possible.

I matched it with the RF P3 - 10", and I love it.

GREAT DEAL

This product is well built and works as expected. I would recommend this enclosure.

Very happy with it! Thanks!

Nice looking speaker box, it makes sound good my low frequency.
any sub, no problem!

Does the trick

Can't beat it for the price. Solid construction, carpet finish seems to be good quality, terminal is good quality, cutout was the right size, everything mounted right up.

Great box!

Strong, clean, durable box! I had my JBL GTO1014D in this box, then my NVX VSW104 in it! Both subs sounded great! Very tight & accurate, but deep & loud as well! Would definitely recommend to anyone who likes sealed boxes! Thanks Sonic for great pricing and prompt delivery!!!

Worked great

Fit perfect and sounds good. Had good bass and made the Jeep thump.

Gets the Job Done For A LOW Price!!!!

I purchased this box for my R2D4-10 because it was a perfect match at .77cuft. The box is very well made and is priced at an excellent price. Shipping alone is probably $15.00 so the Free Shipping was a BIG plus for me. I doubt you could build it yourself any cheaper! The Box sounds great and puts off excellent sound quality. I highly recomend this box if your tight on space, on a budget or just looking for a great sealed enclosure at a great price. Get It While Its Hot!!!

Great for $20 but....

So I have to say that for $20 this is a pretty decent box. The sealing could really use work though. Mine came with one of the rear corners with no sealing whatsoever, the four edges of the baffle board (where the speaker mounts) had no sealing whatsoever, and there is no sealing done on the terminal cup either. Although if you want perfection why are you buying a $20 box?

Great Value

Great Value and Great Seller. Would buy again!

Too small for my sub

Irs a fine box and made of good quality. The only problem I had with it was that it didn't have enough air space, even though it was right for my sub (it feels under powered in this box). It may work better with a sub that needs shallow air space.

Great box

You can not make this box as good as this for the price. holds up to 800 watts going to it with no problems at all.

its good for your sub

I mainly do a single sub with a big amp. I tried a ported box but was not getting the sound i was looking for. This box had a little more volume than my last box. I'll be using this box for a long time.

Great Cabinet for the Price

This cabinet is exactly what I was looking for. Sealed up tight, very sturdy, and inexpensive. You can definitely spend more money on an enclosure, but if this fits your application, you'll be pleased.

Good Value.

This box was part of a package deal. Good deal, box is nice.

This box is unbeatable for the price or more!!!!

I bought this as part of a combo from Sonic and it is a great deal for the money or more - you couldn't build it for this amount! I will buy from Sonic and the supplier of this box in the future!! GREAT JOB!

PROS: Build quality, no leaks, great looking carpet cover!

CONS: Only if you don't have one yet :)

10 box

this a good looking box ,, it dose what a box should do. and it came to my door fast form sonic

Simple is Good!

Simple sealed enclosed works as advertised. Build construction is good. Cannot beat for the $

Use to purchase this all the time

Belva brand is good affordable material when starting out but through out time cca corrodes if you have the money buy ofc cable

Nice Box at a great price!

Got this box because the size was the closest sealed box I could get for my sub (Polk DXI svc 10") I liked the fact that the carpet would match the trunk carpet and that the box is lined with poly on the inside. Box Is built very well. Nice and sturdy and the carpet on it is done well. Got it installed and it sounds great. No leaks or rattles and the sound is nice and clean.

Great Buy

This single 10" box is great, structurally very solid and well covered with nice carpet. I've made many boxes in the past, at this price why? Highly recomended!

Great Little Box

I have a JL Audio 10W6v3 mounted in this box and it plays loud and deep with very accurate sound for a small sealed box. The box is built very well with quality black carpet that looks great with the sub mounted in it and takes up very little room.

Great Value

Pre lined with poly fill is a plus,the bass sounded great for a pre made box

I recommend it!

Finally decided on this one after a lot of research and shopping around. Great quality, great value, fits perfectly in my BMW E30 trunk! I definitely recommend it...

pretty good

A good box only issue I had with it is the fact you have to add wire to it yourself and all the other boxes I have had you didn't need to plus the carpet was messed up a bit from shipping. Definitely suggest for the price and everything else though

Great box for the price

Box is built damn well for the price. Only complaint was some sealant was missing in some spots, especially in the corners. Not a big deal though, I just bought some silicone sealant and filled in the missing gaps.

Awesome Enclosure

Awesome enclosure great "bang for the buck" very nice looking and goes great in any trunk i used it with my 10" power acoustik fubar 10w and it sounds swweeettt

BEST BOX!

Great price, great look, great durability...overall the best box for the buck and bang!

Well worth the money!

I am very happy that I bought this box for my sub woofer. It is a perfect match and I recommend it highly.

Thank you

The box looks great and don't take to much space in my trunk , super fast shipping, thank you Sonic you have a new costumer.

Nice sound and quality

Works great in my Cruze. Doesn't take up too much room but provides nice bass for its small size.

nice cheap box

This is a very nice box for the very low price.

good box!!

recommended for low wattage subs. put my 10"COMP in and it pounds like 2 12". Recommend to everyone
once you put your subs in. it still got plenty air space so its good!

the only bad thing though... the carpet around the wood can tear apart really easy. So when you put it in your car or carry around. Be Careful.
This sub box is 5 STAR!!

Solid Enclosure

Never heard of this company Belva before so I took a chance due to panel thickness & price. The box is surprisingly built well and includes a thin but effective layer of poly-fil which is nice for some subs. Carpet is a nice dark charcoal color and is neatly attached. No visible seams. Using this for a Prime 10" was perfect in volume & cutout .

The only thing I would have liked to seen was wiring included within the box and the terminal sealed which is was not. I took the terminal out to solder the appropriate wire and upon reattaching it, I applied a thin layer of closed cell foam as a gasket o insure there were no leaks. I also sat the subwoofer in place and trimmed the carpet from around it so that a mounting gasket could be applied & effective. Holes were pre-drilled for the sub, then the sub finally connected. No rattles, and sealed up good. This turned out to be a great box in the end and would recommend it to anyone that is in need.

Good sub box

My sub recommends .75 sealed cubic feet of space. I left the padding in the box, but maybe should have taken it out since adding the additional padding makes a small box sound bigger. For my use, I prefer a tighter bass rather than volume or low frequency. That said, I have not removed the sub to take the padding out, its not that much different than the setup I had before with the same sub and same size box without padding. Carpet was nice, very professionally built box. No issues installing a 10" kappa 100.9w sub (no trimming or anything needed).

TL;DR -- Well built solid box, would recommend to others, will purchase again when need arises.

Awesome!

I am reviewing Sonic as well as the box. Outstanding! Ordered on Friday, received on Monday! Free shipping! This Box is quality! better than anything I could get here in AZ for half the price! 3/4" MDF sealant was a perfect bead in all the seams. Carpet is good quality.I will be using Sonic whenever possible!

10" Subs!

I purchases two of these boxes. Good price for both boxes! Durable material made for my competition subs. Thanks Sonic!!

Great deal for the money!

I actually found this box on the Sonic Electronix ebay page and was seeking an inexpensive box for an infinity kappa perfect 10" for my Acura. The air space is a bit more than the sub called for but it is very well made for the money indeed. The Kappa performs very well in it I'm pushing it with a JL Audio HD750/1 which is too much amp for the sub but gives a very clean sound. I really have no cons for the box. It is a great value, is sealed well, has a nice pre installed terminal connection and has nice carpet not the fluffy fuzzy stuff you see on a lot of cheap boxes. If i have to give one con to it I would say the front could be reinforced where the sub screws in but unless you are using like a W7 with ridiculous power this box will serve you fine.

Good Box

Using it for a Kicker 07C104 and it fit perfect and sound good.

works

this box looks like it is made with care. had box for a while and had no probs, most boxs crack or leak air this one is superb

great value

box is well made and strong. you wont be disappointed

good enclosure

this enclosure for your 10" subwooofer is a great buy not only is the box easy to install your subwoofer its is light and cheap a great buy!

good

good box, good price, good deal!

Great box for mb quart 10.

Glued together well and insulated correctly, our mb quart 10 with dual voicecoil sounds clean and has amazing bass for it's size. We modified input port for dual voicecoil, drilled holes in plastic to accommodate multiple wires, then caulked around.

By Lucas on May 31, 2015 Verified purchase

Decent box

This is a decent cheap box, says sealed and it was, all except the speaker side of the box, I sealed that my self and then mounted my FLI Audio FL450S-F2 amp to the top of the box. After amp was mounted in went my JL Audio 10W0v3-4 this is a great combo, I set this in my jeep rear facing in the corner and the bass really hits hard. I would reccomend this box.

High quality box

Well made box that works perfect if your looking for good tight bass...just make sure the sub you use is made for a sealed box.

Awesome box for the $$$$

I was very skeptical about this box when I saw the price, but I could tell from the moment I picked it up it was a quality product. It was much heavier and thicker then I expected, and the seams and joints were sealed perfectly. I was really surprised. This box is every bit as good as one's costing $30-40 more. Good looking carpet, gold plated connectors. The sound is superb with my 10" Infinity Kappa. Perfect 5's.

Great value, works well

A decent box for the money. Was a perfect match for my JBL GTO 10" woofer.

By andrew on July 13, 2015 Verified purchase

Great box!

I bought this box because it was bundled with a Legacy LWF10X and got a fairly good discount from Sonic. I was building a cheap set-up so I chose this. I tested this with my existing amp (BOSS AR1500M) installed in my SUV and it sounded really great. It handled tight bass notes and some very low frequencies. It is now installed in the trunk of my wife's 2008 Honda Civic and is run by a used Jensen amp that I think pumps 150W RMS or less that my friend gave me. Now it rattles every panel of the car especially the rear deck so I need to put some foam underneath it to reduce the rattling. The size of the box is just perfect in the trunk and the overall build is really nice and solid.

sub box

I recommend this product but mine had broken clips, so i was not able to secure wire. Had to tape it.

Great Value

For the price this can't be beat. Only gripe are the terminals used. Kind of cheap, but all in all, an amazing value.

awesome enclosure.
best i used. have a JL 10", sounds great.

good box.

This box is amazing. I have a Pyle Blue Wave sub mounted in it, and it pounds. It is very good quality. I have used it for close to a year now, and it has never given me any problems. Pros: cheap, good quality, does an amazing job. can't think of any cons for it.

Good, sturdy box!

Very nice enclosure for a simple setup, especially for the price! Walls are thick and dense, and heavy enough that I can just put it in the trunk without securing it. Sounds great with an Alpine Type R sub.

Single 10

Great quality product, at an even better price. This box compares in quality to similar boxes that cost 2 and 3 times as much. Hard to beat a box this solid at this price.

Sub box 10"

Speaker box is great, fit my car perfect!!!!!

Single 10" Sealed MDF Enclosure (10SQTC)

this is an excellent box with a very tight seal and it produces solid, tight bass notes. if your only running a single sub, or multiple subs via separate enclosures, i would highly recommend this unit for quality and price.

good sub enclosure

This is a very good subwoofer enclosure. I bought it and put a pyle blue wave subwoofer in it. It works excellent. good price too.

unbeatable price

one of the best prices for one of the top quality boxes on the net. built of very solid material and the carpet looks great. thanks sonic for the excellent price 20 bucks cant beat it.

Crisp & Breathtaking Bass

Paired up with my Boss R1100M and Belva MDFS10, this makes the best single sub setup for the money! Bass is perfect and not overwhelming like my 2 12s were. Very smooth bass. 100% recommend. This is in my daily driven car and I've been running it for a while. Rockford Fosgate

Great sound

Best sub I've used. Have tried infinity, alpine, crunch, and some off brands in the same price range. This one sounds way better. Deeper and louder. Very tight, crisp. In a 1.1 cu. Box. 500 watt amp

By Mark on June 8, 2015 Verified purchase

F150 Supercrew

I was looking to put some bass into the sound system I was building for the truck. As I have gotten older I was wanting a good SQ set up. I chose this sub for its value, wattage handling, & the dvc. I built the box and got it powered using a channel amp and it has delivered. I cannot comment on the durability as I have only had it a month but so far so good.

Great

Great Price, Great Box, I'd Recomend this to anyone who is getting a 10" sub wanting a sealed box.

Very good sub

These subs hit nice with the right power also in a ported box. You can max these out too with sound. Nice and gives you the sound quality you want.

Good extra fine wire

This is excellent speaker wire. One wire has round insulation while the other has square insulation making it easy to identify hot and grounds. My only installation problem was I didn't order enough. I needed a quantity of 2 just to wire a single cab pickup.

nice box and looks good.

the box make my polk audio mm sound good and i can tell the box is durable and will last a long time. looks nice too.

By brandon on June 9, 2015 Verified purchase

Good Entry Level Sub

I always build my boxes myself never buy prefabs. I built a box sealed at .8 and the sub sounded really well for $50. Rockford did a good job with this one. Definitely fills up a 1998 mustang. I just ran one and it's lasted well for two years now run on a 200 watt amp. I would buy again if on a budget.

subwoffer enclosure

needed two for my pickup after shoping around I bought two from sonic electronics. Im very happy with the quality and the price. sonic has great customer service and fast shipping. The enclosure are well made and would recomend them to anyone looking for a quality enclosure.

Basic Box

I do not think i will buy a sealed box in the future as i believe it does not allow for enough bass. But if you are looking for a sealed box have at it. it is built just fine....

AWESOME DESIGN 10INCH BOX

This is the best investment I’ve made, the box looks great and very durable, the carpeting looks excellent, and it’s a light box. I recommend anyone who has a 10inch sub and looking for a box to get this product.

nice loud sub

I have one of these in a custom ported box tuned at 40hz powered by a boss 1100 watt amp. Im giving it 250w rms and it sounds great at lower volumes. When I really crank it up I can hear it outside the truck and it rattles body panels, but it dont have as nice sound quality at higher volumes. Overall its a good sub and the price is great.

Good wire

This wire is great speaker wire. I like the way it looks and works great.

rockford fosgate r2d4- 10

My brother bought me this sub for my birthday, he has dual 12 inch hifonics running 800 watts a piece. My single 10 inch can keep up with his dual 12's if you are looking for good reliable bass I would say that the r2d4 is your best bet.

You get what you pay for.

It's a box. It's got carpet. It feels cheap. It is cheap. Spend more money if you want a better box. If you don't want to spend more money, buy this box.

GREAT QUALITY BOX!!!!

GREAT SUB BOX, BEST PRICE ONLINE... THANKS SONIC, FOR THE BEST PRICE ONLINE FOR THIS BOX, AND EXCELLENT SHIPPING!!!! SONIC IS THE OUTSTANDING!!!!! YOU ROCK SONIC....

BEST QUALITY 10 "BOX

THIS WAS A GREAT COMBO DEAL WITH THE 10" INFINITY SUB WOOFER, THIS IS MY 2ND ORDER, LOVE IT!!!!!

Excellent value

The speaker wire is a good price for the length and gauge.

Rockford fosgate R2D4-10

Great sound and bass also great quality speaker for the price.

Good Sub Box

The box is well made with good quality. The terminal connections have been a problem. The threading is off on them and will not tighten.

Very clean sound..

This sub hits hard, has some shake to it, and is very clean deep sounding.. Its absolutely amazing for the price.. Rockford fostgate did it again.

Good Value

This sub sounds great. After roughly 15-20 hours of break in time it really starts to shine. It's in the back of my crew cab Tundra in a passive box tuned to 34 Hz with a Dayton Audio 10" passive radiator. It's feeding off of a RF 300.1 and after breaking it in it keeps up with the amps power. I have bottomed it out before during a torture test but the voicecoil definitely handled every bit. The duel voicecoil is nice too for extra wiring options.

Single 10" Sealed MDF Subwoofer Enclosure (Belva MDFS10)

This box is well made, but I did have to trim the sub opening larger for my 10” NVX sub to fit, now sub is hitting hard in it no complaints.

Great enclosures

These enclosures are made well, and are the perfect size for anyone looking to install subs without talking up too much space. Great value

Very sturdy and well built. Sounds good too!

This is a very well built box for the price. The wood is nice and thick (that's what she said!). My 10" Kicker sub sound pretty punchy in this box. The only con I have is that it could use a bit more cubic feet of air. This box is pretty much 1 foot square. A couple more inches in each direction would have yielded around 1 cubic foot of volume which probably would be been more within the sweet spot in what the speaker likes.

Quality

The Belva MDFS10 is built very well and is incredibly sturdy.

I could not make a box for as cheap as Sonic Electronics can ship it to my door.

Great

It's a small box that met the size requirements of my sub. The walls are pretty thick and comes pre stuffed with sound deadning material. The my only gripe is that the terminals on the back are not removable so you will be soldering inside that small box. I'd definetly buy again.

Great Box !!

The box is very sturdy and looks great. I was trying to find a .75 cubic foot box for my 10" and this was .77. Installing sub was easy and straight forward and had it in the car, installed, in under an hour.

Phenomenal box for the money

I've had both the 12" and the 10" version of this sealed box. Both times I had single Kicker Solo Baric Classic subs installed. Amazing thump and the insulation it comes with helps.

10" Sub box is great

I puchased the JBL 10" Sub and got the box at a great deal. Fits and screws to box perfectly. Worth buying and would recommend to friends.

By Alexander on January 5, 2016 Verified purchase

great sub and price

This sub hits hard and sounds very clear, I went from 2 15s to just one of these. It has plenty of bass and gets the job done well. For the price sonic has it, its a great deal for a great sub

Good box, not great to install

No complaints as far as the box installed. It does it's job. Installing is odd because there is insulation over the connectors inside the box. You'll have to peel away the insulation and wire it, then get it back in place. Or cut a spot out for the wiring if you'd like

DOES WORK SON.

Yes. Get it. Just put 2 of these in my 2011 Camaro, and now my rearview mirrow is always looking at my feet. Got it in a custom-sealed box hooked up to a mono class D 2000 Watt Power Acoustik (pushes half of what it says) so it worked out perfectly. Slaps harder than I expected, and is a little strong for my stock speakers, so I can't wait to upgrade those too. GREAT BUY! Extremely impressed.

Not top of the line but this box is good paired with the right Sub. I have NVX VSW102v2 in this and it hits hard for rock and country, Plays some rap good for a sealed box. Just make sure you have the right Sub and amp settup you're good.

Fantastic value

I was planning on making my own enclosure, but I actually saved money to buy this one that was already built and lined with sound deadening material. It's a solid box and has done a great job housing my 10" Alpine that runs at about 500 W RMS. It was super easy to install my sub into. I'm sure it's not the highest quality box out there, but it a great box for the value!

Good for a while

These subs are great after you give them a couple hours. I had mine for 5 months then they unexpectedly sounded like s***

Came as described. It is really a nice box. It seems to be of good quality. No complaints. I have an Alpine Type R 10" in it and it sounds really good.

LOVE IT! This sub does a great job of balancing my factory system. I do NOT want people outside my car to hear my music. This sub is perfect. I love it! Looks cool...sounds great...what more could you want?

Single 10" Sealed MDF Subwoofer Enclosure (Belva MDFS10)

I was sent this as a free gift with my sub purchase and surprisingly this little box sounds pretty good with an idq 10v4 in it!

Greatc Value

Mounted 10" woofer and drove with Acoustic Image Clarus Series 4 plus. Amazing deep bass.

It works well.

It's a nice little box for a good price. I got a deal on it with a sub and a code so for the box and sub it was under 100 bucks delivered. I cannot complain about that. I am actually using it in my house as a home theater sub and it works well. It is a little big for the trunk of my car (Impreza), so I will continue to use a smaller box in there. I did try it out in there and it did fit, but took up too much room. It takes up very little room in the house though.

More Than Enough Power!!!

I purchased the Rockford Fosgate R2D4-10 because of the Positive reviews and because It was a perfect match for my Rockford Fosgate R250-1D amp. I had (1) of these subs installed in my Ford Explorer using the 8 Gauge Rockford Fosgate RFK8I kit. Also bought the Belva 10" .77cuft sealed box from Sonic. Let me tell you that I really couldnt be more pleased with my system. Sound Quality is excellent. And this combo really BOOMS and HITS HARD!! I wanted something simple and not too overpowering. I really got more than I was expecting. Sonic Electronix provided supurb FAST service. I live on the east coast and ordered Sunday night, recieved Thursday and had everything hooked up Friday morning. I couldn't be any more happy with my purchase. If your looking for a single subwoofer with great sound quality and bass, the R2D4 w/ RF R250-1D amp is MORE THAN ENOUGH POWER!!! You won't be disappointed! Thanks Sonic for the great service, and I will refer you to everyone!

Big sound in a little package.

Highly recommend these amps. I have two of them in a A-trend box under my back seat in my F-150. The sound is amazing. I blew my installer away. He liked them so much, he's going to carry them in his shop.

Perfect fit!

Well built sub box at a great price! Shopping locally, I couldnt find a box that had the correct cu ft of airspace let alone 3/4 mdf with fill.

This sub hits hard for its size and price. I am pushing around 200 RMS at this guy from a Rockford R400-4D amp. Produces deep bass without any hiccups. Strongly recommend to anyone looking for a sub that isn't too powerful yet delivers strong bass.

BANG FOR YOUR BUCK!!!

Rockford never ceases to amaze! I picked up 2 of these for the system in my CRX, wired in a series at 2ohms with my amp pushing 300w rms to each channel... WOW. I never expected to get such a clean, tight kick out of a tier 1 sixty or so dollar subwoofer. Whatever your genre is, this little beast will surpass your expectations when tuned correctly. The perfect solution for someone on a budget, I highly recommend it!

Decent, but not outstanding

I bought one of these subs to replace a 10-inch Eclipse 8010 that gave up on me. The Fosgate doesn't hit even half as hard as my Eclipse, and it doesn't hit the deep lows hardly at all. It hits just enough so that I know I have a woofer back there, AND just enough to keep me satisfied until I can get a sub that really hits. If you have been riding around in your car listening to a couple of 5-inch, 3-way speakers and this is your first sub, then it will probably sound great to you. Keep in mind I was spoiled by my previous sub. It truly is a "get what you pay for" game when it comes to car audio.

Single 10" Sealed MDF Subwoofer Enclosure (Belva MDFS10)

It holds the sub and does it job nothing more nothing less.

Clean Looking Box

Box came in promptly and is actually a nice , poly lined sealed box. Looks very clean. Would recommend as the time and material you would have into making your own would this is easily a better value.

10" Subwoofer box

Put together really well. I just think it's a little small for my subwoofer. But that was my fault. I need a box with more cubic feet

Awesome

Coming from Kicker Comp 8s to these in my Toyota pickup definitely is quite a difference. Put each one in a .58 cu. ft. sealed box behind my seat, and they kick HARD. And I'm someone that doesn't really like to crank it up and pound them to their limit. I decided to port one at 43Hz since that's what Rockford recommends. It puts out way more bass but I think I need to tune it lower since they have some trouble with lower notes that my 8s would pick up. Overall, Rockford is now my go-to stereo brand instead of Kicker. The quality of sound is much better.

My Rockford Fosgate P3 sounds great in this Enclosure!

I bought this enclosure for a RF P3D4, this box is a perfect match. The enclosure is well built and very sturdy. Only negative thing I can say, is the polyfil covers the entire interior of the box. You have to cut out the polyfil covering the speaker terminals.

nothing special

They are OK subs. I bought 4 on sale for grins and giggles. They are no where the Sq or spl of my 2 12" alpine type r's. Of curse the 2 alpines cost me more than the 4 of these. Running a kicker cx1200.1 so I am getting 300w rms rated to each sub. I am non plussed and I paid 28 a piece.

Impressed.

This sub impressed me quite a bit. I listen to all kinds of music, and this sub has handled what I threw at it. It's really clean, clear, and crisp. I was going to buy a P110S4, but this sub is a lot like it. The looks are a bit different, but the power ratings, and the fact that its a DVC, is what I like. I have it on a RFP200-2 amp bridged mono to 4ohms. It's all ran from an RF 4g amp kit. 5 stars.

Great sub

I was more than pleased with this product. i put two of them in a buddies truck in two sealed boxes i also got from sonic and man do they sound really crisp and clear. they also look great with the standard rockford quality. i would recommend this sub to anyone

Great box

Loved it my subs fit perfectly in it and sounds amazing.

Great Value

Great product for money. Handles plenty of power and hits hard. Looks good but its a sub. Would recommend this to anyone thats looking for a 400-600 watt subwoofer!

Pleasantly surprised

I'll be honest, although I've owned Rockford products in the past, I didn't have very high expectations for this sub however, I was pleasantly surprised. The speaker produces rich, deep bass without needing too much power. I have this powered by a Kicker DX250.1 amplifier and the sub is in a vented box. The amp is not even up 1/4 of the way and it hits harder than some high end subs that I've heard and have owned. I highly recommend this for anyone that's not looking to spend much and wants great sound. Shipping was fast and free.

THESE ARE AMAZING

These subs are amazing, they are built really well, have extremely good sound, and I have absolutely no complaints. I have 2 of these in my 2005 Silverado and they hit like 12s with a 1000 watt pyramid amp. You could not find a better deal anywhere on subs as great as these. I personally recommend these to anyone out there looking for a nice system!

I got value for my money

I went from an 8" Rockford Fosgate P3 shallow mount I was using in a factory enclosure to this one it sounds way better I should have done this a long time ago.

RF 10" DVC 4 ohm subs

Needed a sub to fit a small sealed enclosure.

Not listening to rap or bass music constantly but would like to have something that "can" perform in that situation.

These subs worked out perfect to add substantial bottom end to a complete system in a crew cab F 150 under the rear seat

I would by them again if needed

Incredible price

At this price point you can not top these. I am powering these with my old school punch 500 amp and the sound great. Thanks Sonic!!!

By Dennis on July 10, 2020 Verified purchase

Great bang for the buck

A pair of these went under the back seat of an Avalanche. Space was at a premium forcing the need of a shallow mount speaker. The sealed box matched the volume required for these speakers. We wired the dual voice coils in a combination parallel and series to achieve 4ohms with a bridged Pioneer 1000w amp (420 RMS). Sound is very deep and full but not overly boomy. Very pleased!

Decent sub I guess...

I’m a huge Rockford fan and have run nothing but Rockford for years in my vehicles. I saw these subs and figured I’d try them since there not much different from the punch series. I bought 2 and paired them with a Rockford 750 RMS 1 ohm mono amp. Plenty of enough power for the subs and not gonna overwork the amp. Both subs are blown and cracking and it hasn’t even been a month since I bought them.. very disappointed in these subs..

Great Speaker

I always buy Rockford subs. This one, as always did not disappoint. Would recommend any Rockford subwoofers.

It sounds great and I got the item quickly I will tell my friends

Well it looks great I don't have screens on my box but they look really nice.

Great subs

Fast free shipping....subs sound great....hassle free service thanks...!!!!

Super hard hitting !

Only the 2nd pair of Fosgate subs I have ever purchased and not sure why. Great subs for the money !

good price excellent speaker

very good speaker for the price. they sound excellent in my chevy. I would bye these again if ever need good speakers

Wonderful buy

Great 2-ohm sub if you’re needing something in a small enclosure. It’s under my seat in my ram 1500 and sounds like a 12” sub. I love the dual voice coil. It gives me the ability to run it 2 or 4 ohms. Highly recommended for the price and output.

awesome

have this in a 05 colorado single cab wired to 2ohms with a power acoustiks 2400 watt max amp...gain set less than 1/2 in a q power sealed truck box. slams! looking forward to getting my 2nd one and possibly switching to ported! may not be the most expensive but I have absolutely nothing bad to say about this sub after taking a beating for over a month from everything slipknot to ice cube full blast!

Nice enclosure!

Very well made, not heavy. I love the design. Sounds Great!

Koopers Review

Rockford Fosgate Sub Woofers

Hopping in a car with Rockford Fosgates installed is a different world. One may not know what Rockford Fosgate sub woofers are but they are pretty self explanatory. They produce a lot of bass which some people can not handle, but I can. Out of all the subs I have installed in my car, these are definitely the best speakers. From what I have learned from having these speakers, they give great bass, can unconnect very easy with just a screw driver, and the best part when you are blasting music the whole neighborhood can hear you even with the windows up.
First thing you look for is the quality and the better they are the more expensive. But when I was looking I wanted to have it where my bass is overpowering, the sound. Any song is good with the right amount of bass. These speakers are meant to be loud so its hard to blow them out. When you have the right set up, doesn't matter who is in the car anyone will like them because you can turn the base all the way up and all the way down. No one can compare speakers with me because Rockford Fostgates are the best. JBL speakers are not the best and I returned them after I had them for a week.

The initialization with Rockford Fostgate speakers are very easy. You just need a screw driver and a brain to unscrew a couple screws. My other subs require other tools to take them out of the box and it was just a pain. When having good speakers it should be easy to install because your paying a lot for something that gives off sound. Its the best to have my speakers turned up loud enough so that people can feel the base as I drive by theirs houses. I share a car with my twin brother. When he comes home and I'm sitting in my room, I can feel and hear my car. However there are some disadvantages because there always is.

Rockford fostgates produce a lot of base but you need a power source for all the power that is needed. They are very good speakers but nothing is perfect. My car is a 1998 and it hasn't had its battery replaced and the subs work perfectly fine. Another downfall to these speakers is that the more you like it being loud the better chance they are going to blow. These speakers are meant to be loud so there is a slim chance that this will happen but it still will. I have had my speakers for about a year now and they have not blown yet or even coming close to it. The final set back on these speakers is that they can over heat the amplifier. They are running such high wattage and sometimes if you play the right song it could blow. All these problems have a slim chance of happening but there is still a chance.
From what I have learned These subs are the best all around. I would give these speakers a 5 out of 5. They give great base , and are really easy to install and uninstall. For the amount of money spent on these they are worth it. I recommend these speakers to any one that loves base. They are perfect for everyone and anyone that loves loud music.

Never Disappoints

Even as an entry level subwoofer Rockford never lets you down. Hooked this up in a ported box with an old punch 200 I had. Sounds great!!! Would recommend to anyone looking for a little extra bass.
