Mounting Depth is NEEDED

One thing that NEEDS to be in the description is the MOUNTING DEPTH of the box. This is CRUCIAL for determining which speakers will actually fit in the box. Once I received the box, I estimated the mounting depth to be somewhere like 5.5" for the sub. So this does limit certain models of subwoofers, but the one I chose fit perfect. I also enjoyed that this box came with poly-fill. Sounds great with my Alpine SWE-12.

Single 12" Subwoofer Angled Truck or Hatchback Box Enclosure

it is as discribed , well built and speaker fit well. it was a good price and had no defects.

belva 12" subwoofer enclosure

excellent subwoofer enclosure for my 12" sub. The quality of the materials and the solid feel of the box exceeded my expectations

Awesome Enclosure

Didn't expect a insulated enclosure...Everything fit prefect and the quality was far more than i thought i was gonna get. Gotta get another one when i add a new deck to my van.....Great speed in shipping too.

Excellent Product!

This box is very well built, great size, and is completely air tight. I've never had a box that was cotton lined and let me tell you it makes a difference. Great product I would highly recomend!

A Super super happy man!!!

I bought this Single 12" Subwoofer Angled Truck or Hatchback Box Enclosure a few days ago. So I cant explain how much happy I'm listening my music with this box, I'm an immigrant from Colombia who like to listen music such as Salsa, Reggueton, Merengue a real Latin guy. The sound is something so crazy (Perfect Sound - Space) in my car, Now I'm able to move all the toys of my son in my 2010 Toyota Matrix. If you want to have a good space & sound this is the box for you. Don't be scary for the size of this box. ;) I'm a happy Colombian.

Nice Box

I purchased this box to put a Hifonics HFX12D4 in. The box is well made and falls within specs for the sub. The carpeting, cutout, poly fill and terminals are high quality. I added about 5 oz of polyfill to make the sub think the box is bigger. The box also has a small footprint and fits easily in the trunk of my Yukon. This combo is matches up well and is highly recommended. Plus, the pairing offers a great value if you want strong bass on a budget. Sonic did a great job with the shipping :)

speakers box review

Great box. Good waight,shape and easy to install a speaker to. Looks great in black. Recommended for any impact car or truck. Sturdy box no vibration.

Good Product for the Price

Good construction but it really flexes from my Rockford P3 shallows so I had to reinforce it with resin and fiberglass

Works great.

I bought this speaker box for a mustang but I ended up with it in my extended cab f150. I raised the rear seat up 2 inches and put in a alpine sub. This box hits hard and it is sturdy. It also looks nice in my truck.

Rockford Fosgate R2SD4-12

At first i was very unhappy with these woofers. But after a week or two of using them they seemed to get louder and better. Still not what i was hoping for but i can't complain with my crappy amp. I have a crew cab with two of these behind the seat. They do a good job of putting out the bass threw out the cab.

Very nice shallow subwoofer

I bought this for an install I did for a friend. I wish we could have used a larger box. This is a great sub that would be even better in large box.

Subs review

i would recommend these to anyone. they sound great. Haven't had a single problem with them. 2002 chevy silverado 1500hd crew cab. they're under the seats.

Nothin like a Fosgate

I am i huge fan of this brand and the R2sd4-12 was just another example of why it is such an amazing brand. This is an excellent subwoofer, it's cheap, and it fits in small spaces. Can't ask for much more.

Update

I did order another one and wired the dual 4 ohm voice coils in parallel and surprisingly I put a multi-meter up to it and measured for ohms and got a reading of 3.6 ohms on both subs. Not bad, not bad at all.

thumping

I have 2 of these installed in a sealed unit on the mid gate of a 2002 avalanche. I have a planet audio ac1800.5 amp pushing them and they sound sweet. I like the tight clean sound but the will boom with the best.

Very good shallow mounts

Mounted 2 of these in a sealed box under the rear seat in a supercrew truck running 1000 watts @ 1 ohm. The box spec was just over .5 cu ft each and even with poly fill the air space is a bit under but I heard these could probably handle it and they did. I've worked at a pro installer years ago and I would not have expected the bass quality these produce in such a shallow mount and tight box. I'm pretty impressed and at this price I'd say they're tough to beat in terms of value.

awesome!

If You're Looking For Huge Bass, These Are Not The Subs You Want. But If You're Looking For Great Sound Quality With GoOd Thump In A Small AreA, These Are What You Want! Tight And Responsive, Clean SOund, And A Great Product. Would Buy Again!

Great Sound!

The speaker sounds incredible. I built a speaker box to replace the stock floor in the hatch area of my Mazda3 because I didn't want to use up all of my valuable storage space with a speaker box. Since my dimensions only allowed me a 3" mounting depth and approx. a 1cu. ft enclosure volume, I had to start shopping around for a shallow mount speaker that would work with such a small enclosure.

I have the speaker powered by an old Kicker ZR360 in bridged mode @ 4 ohms. With this set up, I'm putting about 360 watts RMS into the speaker. Let me tell you, the speaker downright bumps.

I wouldn't hesitate to recommend this speaker to anyone looking for a shallow mount and/or low volume speaker setup.

Great value!

It's hard to find a better value than this shallow sub. It doesn't hit as hard as my 12" L7 on the same Punch 300 amp but that's kind of comparing broccoli to asparagus.. Buy this sub! Awesome value.

Fits good

Good quality and size for what I needed. Box is made good. Not cheap.

Single 12" Subwoofer Angled Truck or Hatchback Box Enclosure

universal box its great for regular cab pickups would recommend

By Anonymous on July 20, 2018 Verified purchase

sounds great

I had them bridged to 2 ohms to some old 800watt amp i bought for 20 bucks. they slap! knocked super hard and sounded great. i have 2 in a truck box for my ext cab silverado. the amp kept going into protect mode...come to find out it was the wrong amp...so now i have them wired to 4 ohm set up and they just sound like good speakers. I ordered a 1400 watt amp so we will see how they like that!

Great box

It looks and sounds great i would buy this again it was shipped in a very short time

Amazing subs .

At first like everyone else i doubted that these would hit hard brcause they were shallow. I was so wrong they hit hard . I can be heard coming down the street . And it doesnt take much space . I have them in my dodge ram quad cab and these are so worth it . Such a great product.

WELL BUILT

First, I purchased a similar box from another company and the box rattled badly. This box from Sonic, was cheaper in price and much better built. Great box at a great value. I would recommend this product!

Not Bad!

I got this box to fit in my 2013 nissan cube. Placed a 12' JL Audio w1 in it. Sounds good for a sealed box. Just got to adjust the amp. Sealed boxes tend to want more power!

Gonna order me another one

I have a 1974 GMC single cab truck, I dont have very much room to work with and these are just perfect for the job. At the moment I have just one being powered by a 250 wattbridgeable Wal-Mart brand amp and have placed the driver in the middle of the bench seat, I can feel the bump but only on one side of my body, must order another one for both me and the passenger. Will also order an amp to match. :D



I just like the bump. :D

Solid Box for the price

Fit perfectly under the rear seat of my GMC. Nice quality and solid build for the price.

Excellent shipping execution!

I think this product was an excellent value and it shipped quick and arrived in mint condition, despite my concern about the handling given the weight. I wanted a vented enclosure but carelessly selected the wrong model and didn't realize it until it arrived but it sounded really good for only providing 1/3 of the internal volume needed for optimum performance. None the less I recommend it.

Cheap

Works great for what i need it for and best of all it fit behind the seat of my single cab truck

By Zach on November 9, 2017 Verified purchase

very nice

This box is built very structurally sound. Looks great as well even has insulation inside very nice product

Well made, not expensive.

I like this little box having a small car and needing the space this was the perfect addition.

By Russell on March 18, 2021 Verified purchase

Great little box

I'm really liking these boxes so far. I have a single cab 07 colorado and I have two of these boxes sitting behind the seats while maintaining plenty of room to be comfortable driving(I'm 6'5"). They sound great with the speakers i have paired with them, Sundown LCS 12's.
The mounting depth of those speaker are 6 1/2 inches in case anyone was wondering and yes, they fit like a charm.
Build quality is great, also. I liked that they it came with pre installed filler material.
The speaker terminals are also nice, but they do not come with speaker leads for inside the box so keep that in mind when ordering.
10/10 would recommend for anyone with size constraints.

Nice Product

I would recommend this box, pay attention to air space and the size. Great quality but I ended up having to build a custom box to fit under my 1500 back seat.

It's a box

That is well built. Can't complain. Works well with the shallow MB Quart that it holds.

Great value

good price for a pair a single 12" subwoofer angle truck

Rockford ROCKS!

Bought this to add some umph to my F150 Super Crew stereo. I have a bridged Rockford Punch P3001 and a single sealed enclosure under the rear passenger seat .9 cubic ft. The single 12 produces very tight punchy kick drum and produces low end instruments extremely well. For my situation and considering the room restraints for the box, I can't imagine anything sounding better. I have to keep the Sub output on my Clarion head unit turned waaaay down to keep it from completely drowning out the rest of the system.... if it suits you space and requirements, buy it, you wont be disappointed.

Amazing product!

Well made and fits behind my seat perfectly as well as it’s very well sealed!

Great value

very good subwoofer, to me was great sound and good price

Rockford Fosgate Prime R2SD4-12

This one sub beats hard in my truck. Now about to put another one in. Great Sub for the price.

Rockford Fosgate Prime R2SD4-12

I am very pleased with the sound quality of this speaker I have one 12 and a mix match set of 10'S MEMPHIS POWER REFERENCE AND A AMPLE 400W ALL ARE IN THEIR OWN BOXES 1000 WATT PIONEER AND 250 PIONEER IN A ASTRO VAN BEAT SO HARD KNOCKED OUT THE SIDE GLASS ....

Great speaker

I would recommend this speaker for a single cab, I put it in my 85 f-150 and it sounds great I haven't had any problems with sounds quality and it definitely has a thump.
