Customer Ratings & Reviews

It's a boxf

What can I say? It's a good box, and spec for the subs I got. Good price, good build, and the sound is heavenly. For someone like me (ie, not a carpenter, not even close) this is a good choice. I'm not a fan of banana clips but they are prevalent, so there you go. It's ready to go.

Awesome Item

I purchased the Belva MDFD10 10" Dual sub encloser. One of the better boxes I have worked with. Easy to use and hook everything up. Fast shipping and it was at a great price. I highly recommend this company.

Sub Box

Very good sub box. Great price for the sub box.

Great box!!

The box was a great value and came pre filled. Amazing sound highly recommended.

Excellent!

Great sealed box. Nice pricing. Good sound and perfect size.

awsome box

Makes my 10" Rockford r2's sound like 12"s. Can't believe how great they sound. Would like to have the speaker wires already installed in box.

Amazing buy

This box is absolutely amazing for the price. the terminals are on the side so that I can mount my amps on the back, and the box is black, so it matches my trunk.

Affordable

For what its worth, I would recommend this box if it suits your woofer specs. I loaded it with two JBL CS1014's, I now have some clean bump in my trunk.

Good prefab box

Good quality for a prefab box. I wish they would have skipped the connectors so I could have just drilled my own but other than that solid and exactly as advertised. Great quick way to get your system in your car.

Great little box

I've seen a lot of good reviews in customer service for sonic, so I took a look at there site n was blown out of the water with all the variety of high quality stuff and at a great price so I looked for a box n got this one. It's not super huge so I have some space in my trunk to utilize for groceries lol. Plenty of room for the subs hits extremely nice live that it is poly filled. Will be back to Make more purchases thanks sonic

great buy

good bass for two ten subwoors.my bro says sounds like two 15 inch.

A different usage ----

I was looking for a small enclosure to use for a bass guitar speaker cabinet. I installed (2) Eminence Delta 10 inch speakers, and installed plastic stacking corners. I also removed the plastic jack plate and replaced it with a rear port tube. The cabinet sounds GREAT ! The cabinet is constructed well, but the packaging leaves a bit to be desired. The cabinet arrived with damage to 2 of the corners, but the damage was covered by the plastic corners I installed. A slight variation from its intended usage, but the outcome was good !

Good box for the price!

I ordered this box a few weeks ago and I have to say for the price the box is a great buy. You will need to re-seal / re-caulk all in the seams and speaker terminals on the inside of each chamber to get a tight seal, but this is normal with most prefab boxes you buy. I have had to seal every prefab box regardless if they say it has been sealed or not due to the fact that prefabs 95% of the time are never sealed on the front baffel / base board were the subs are mounted. Seal the box nice and neat with some silicone / caulk and throw in some fiberfill and you are good to go. Great box for the price and can't beat it.

Good buy

Box was packaged well. Cleanly built, 3/4" instead of 5/8", seperated enclosures, sealed, insulated, would use this brand again.

Great Box

The build quality is excellent. All joints sealed. It really is MDF! Can't wait to hear how my subs sound in it.

GREAT BOX AND THE PRICE IS AMAZING FOR THE HIGH QUALITY OF IT

This box gives great solid sound and is not big and bulky like other boxes and its price makes it even better I would imagine paying much more for something of this quality

Nice dual sub box for the price.

The box is well constructed and the wire terminals seem to be decent enough and the interior of the box comes coated with poly-fill. It fits easily into the trunk of my Oldsmobile Alero and offers all the sound I need. I currently have 2 Rockford Fosgate R2D2-10 subs installed in it, running at 2 ohms and 250 watts a piece.

Not a bad little box.

agree`d with a 3 star reviewer

this box doesn't get too loud and isn't as bass as some but it can be tuned pretty low.. it's a cheap dual ten box... what more could you want?
Be prepared to know you must wire this box up on the inside.. MAJOR GRIPE THERE!

Great Sub Box

Good solid unit! Gives great low end with the Pioneer subs!

Good sounding box

I bought this for my wife's car to house 2 10s. Unfortunately I looked at the wrong sub specs. This box is 20% too small but the subs absolutely shake and get super loud. Even with the rear seat up I still feel the pressure in my ears. Great deal for a prefab box. We get great sq out of the subs too. Not just loud.

Great price and build quality. If you do not want to build a box, by a Belva enclosure. Well worth it.

good value

Recommended for a decent cheaper box. Tuned really low with my titanium t1000's. I had to drill notches in the mounting holes for my subwoofer cooling fins. Wood on the mounting side crumbled a little. Not a lot of punch but definitly gets loud when the bass is low.

soild box

Best cheapest sound box u can get snd still get nice sq

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

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.

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 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.

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.

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.

THIS BOX SUX

Do not order this box you are getting ripped off. The demensions say 31" in length, but it actually 25" and it don't even fit a 10" sub.

-----------
EDITOR NOTE:
The cutout is 9-1/8" which is standard for 10" subwoofers. Additionally, the incorrect length of 31" listed has since been revised to list 25".

Fast shipping!

Nice product, as described with Fast Shipping! Would buy again!

Belva MDFD10

great enclossure. enhanced the sound of my subs and the entire system.

Rockford fosgate R2D4-10

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

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.

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

Rockford fosgate 10s

These speakers work very well and have a good bass hitting sound especially in the lows, very nice speakers and will fit in a single cab with perfect room.

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.

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***

GREAT

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?

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.

Good buy

Really no reason to build your own basic box when this is available. If the box volume is right for your particular speakers then you will not be disappointed.

Great product

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.

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.

Good quality. Low cost

This was a great box. Sounded great and was impressed by the build and price.

By Robert on September 27, 2015 Verified purchase

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

2 JL AUDIO 10w3v3's

The box was super clean all the way around. Solid. True 3/4. My 2 JL 10w3's are sounding quick and hitting hard. I like them. If there we're 10 of these to choose from, i would have chosen this on that they sent...no dents, no torn fabric, wood solid, no vibrations of box or air when speaking banging.

2010 ram

I have 2 of these in a under back seat box and they sound really good with a good amp.

Easiest and friendliest people I ever had the pleasure of dealing with thank you so much

As long as you do your homework on what you want you can get it from them for half the price as almost any one else and the best part is I didn't have to deal with a computer or a robot

Fosgate R2D4 10" subwoofers

I realy like these subs. They sound realy good at all volumes. The DVC lets you wire them in many differant ways. They are well bulit and a great value.

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!

For The Price Can't be Beat

I set out to build a budget system that bumps. After completing my install and firing everything up this box is a great quality for the money. It's not going to blow the doors of more expensive or custom made enclosures but damn this one is great pre-made alternative. Only complaint was it shows wire being attached to the terminals however mine did not have that. Not a huge deal but for someone looking for that may be an issue.

Great value

My car trunk space is limited but it fits nicely

Perfect size

Its the right size and air requirement for my JL Audio 10's. Very nicely built box. I'm happy with it

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.

Great value

Great sound lots of bass. Easy to install & lightweight.

Strong little box!

This is a great little box for the money! Heavy duty it’s about 35lbs.

Great box delivers superior sound

Perfect sized sealed box made very solid and mine handles 2 - 10" Pyle Blue Wave DVC's wired to 1 ohm. A Rockford 750 mono 1 ohm stable amp handles the 500 RMS and 1000 peak watt speakers and the box and it's construction and size make it beyond awesome and perfectly compliments the entire system. Great buy. Highly recommended.

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

By TeamNolen Audio on December 18, 2017 Verified purchase

Awesome!!!!

Gave my bass an instant tightness and solid, really recommend.

Dual 10 inch sealed enclosure

I would recommend this enclosure because it's very strudy high quality carpeting, the carpet looks amazing nice little heavy box perfect for my small system.

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!

Well build

Box is well build and good finish but its is verry small for most 10s. Fits very nice in the truck but small for 2 10s...

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..

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.

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!

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.
