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:)

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.

nice sound

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

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

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

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.

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.

Good wire

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

Excellent value

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

Great subwoofer

This subwoofer has amazing bass for a shallow mount plus it's has a well built frame.

Great

Installed this in a custom sealed box in my 350z and it sounds great. I had the old, thicker 12" Type R and this sounds just as amazing. I even installed this in the worst location (the compartment behind the driver's side seat in the 350z) and it still sounds awesome. Can't even beat the price anywhere else.

Blows easy

I bought this subwoofer a year ago and put it in my truck with the alpine pdx-m6. Both units run at 600w rms and I somehow blew the sub the same night. Granted my wiring might have been the problem. I then upgraded some wires and got another one. (No warranty) this then sounded great and was honestly a wonderful sub! I had it in a down firing box under my seat and if you stood outside of the truck you couldn't hear any obnoxious bass. But inside the truck everything vibrated crazy! But then it blew randomly one night at sonic, without being turned up. These shallow mount subwoofers aren't able to take the abuse as a regular subwoofer and although it sounds good the reliability isn't there.

Good sub

I had this sub installed in a 06 f150 supercrew under my back seat. This is a good sub and it sounded great. However for the price(currently 309.00) and the single voice coil config, I would recommend something else. I currently own a 2011 supercrew f150 and for the price of 1 of these subs, I was able to purchase 2 skar audio vd-10(10") subwoofers and a box for under the back seat. I must say these 2 dvc 10" subs have more wiring options than the Alpine. They also blow the single 12" away. Using an online port calculator I ported my current enclosure to around 35 hz and they sound incredible. They shake my truck like the Alpine never could. The point I am trying to make is that while Alpine has a great product, I believe that for the price, there are a lot more options out there. All it take is some patience and a little research.

Nice lil sub

Very happy with this product. Good for small spaces and surprisingly loud. Could not really fault this product. Perfect for what I wanted.

Love it

Love this woofer.

Solid Sub

Bought this sub to go in my truck due to lack of space. I have had Type R 12"s before and they sounded great. Props to Alpine for getting it right on the shallow mount. I have heard several shallows, and none compare. Just one in a small box hits pretty hard, it won't blow your mind but its a good sub. I would not pay what other places charge for this woofer, some up to 500, but for what its listed for here its a great deal when space is an issue. I will say the box and power are very important. I had it in a .4 cubic foot box and it sounded terrible, switched to a .75 box and it made a world of difference. Give it at least 500 watts rms too, trust me it needs it. Also, make sure to get a grill, although its constructed very well the cone will take dents very easily.

Great but be careful

Had these in a sealed box, the box cracked and they took some damage from that but they played on. Both blew about 6 months after owning them of hard playing. Ordered 2 more now if these blow again ill probably switch To something different but overall i like em. They hit hard enough for shallows. I have them wired to 2.3 ohm in series. They dont drop as much as they should and so they dont get as much power from my amp as they should. This brand new one i just got rattles when it plays already. But still plays fine.

Very clean bass

I am very pleased with the performance of this sub. I was skeptical about how good it would sound compared to a regular 12" and it totally exceeded my expectations. I am running it with an '10 Apline PDX M6. I built the enclosure to manufacturers volume recommendations and it's perfect.
I had to custom build a funky shaped box to fit behind the back seats of my '09 Tacoma double cab. I went to a few car audio shows and have by far the highest SPL Tacoma in Edmonton with an OEM style system (no huge box in the cab)

As long as your enclosure volume is correct you will love this sub.

Great shallow sub!!

I bought this sub to go in my 08 Tundra. When I started my audio build I initially went with the Rockford P3 10' shallow sub, then upgraded to the P3 12', and finally to this sub. This sound undoubtibly sounds better that both of the previous subs, it will really handle the lows alot better than I expected. And right now I only have and MRP 500 pushing it. I am not even sure I will upgrade the amp it just sounds and pounds so good now. It is a little $ but you get what you pay for, and out of all the shallow subs I have heard this one is the cleanest, tightest, most accurate I have heard.
Semper Fi

Fits good

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

good quality

Would recommend, good sound solid product.

ALPINE SWR-T12

The slimline Subwoofer has a nice sleek design and it sounds great. I also liked the service that sonic Electronics provided to me here in Australia, very reasonable shipping cost for an item this size. Thank you. CH

Sounds great

I had 3 of these installed in my dodge 1500.
The sound is unbelievable. I have a Rockford
Amp pushing them all in a series with a 1 ohm load
Would defiantly recommend.

Nothing else compares

WOW!! I must say that alpine did it again! This shallow mount sub is by far the best i have heard! If i didnt no that they were shallows, i could swear the sound like reg 12s. Dont settle for anything else!

Good Sub!!

I have an f 150 supercrew. I have the alpine in an enclosed box underneath the seat with an alpine m500 powering it. The speaker hits hard. It rattles my rear view mirror. The range is pretty good, but it doesn't hit as low as my old 12" kicker cvx. However it's compact design eliminates a big box on my back seat, and I love that. Overall, I love this sub. A definite bonus addition to replace big bulky boxes sliding around the back seat.

Great Sound!! Not Long Lived!!

I got one of these T-12 for my 07 chevy crew cab. Built a custom ported box too Alpine specs to fit behind the back seat. I'm running it with a Kicker ZX1000.1 (4ohms 500watts rms). I have had it for less then six months and it is dead "internal meltdown"!! It had awesome sound, hard hitter, feel it in your chest!!! When it went i was not even playing it loud. This is the only sub i have ever blown. I've had Kicker & JL. Hope this helps somebody in the future.

Great Sub

I bought this sub 6 months ago and put it behind the seat in my Dodge Ram 1500 standard cab truck and it pounds so hard. I would definitely recommend it to anyone who's looking to get a lot of sound and power out of such a thin sub.

Great box

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

Not bad for a shallow sub

Very well built thin/shallow sub. If your restricted to needing a shallow sub this is one of the best out there. Very clean in a sealed enclosure for one 12" at roughly .72 ft3.

Not as much output as a regular sub so keep that in mind. Worth the money if you have to go this route.

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!

By Steve on January 16, 2020 Verified purchase

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!

Solid Box for the price

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

By John on January 26, 2018 Verified purchase

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.

Rocks!

It's the slim design of course - fits right under the seat in it's enclosure in my pickup. But I also wanted a sub that provided clear reproduction without being boomy. This Alpine meets its traditional fame for doing just that. I listen to a broad range of genres and this sub is perfect for everything from classical to prog rock.

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

By alfonso on March 5, 2017 Verified purchase

Expensive and not worth it

I purchased two of these for my new tundra to hide under the rear seat. I have them powered with a 1500 watt rms Rockford fosgate amp. Set to 50% gain. After about 15 min of playing them hard they both blew. I have been going through warranty for months trying to get them back. I have owned kicker solo baric, JL W3, and Rockford Fosgate P3' subs and they were all louder than these alpines and cheaper. Keep in mind they werent't shallow mount but I am very disappointed I have only gotten 15 min of play for over $1000. I would never recommend these subs to anyone!

Amazing product!

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

Great Sub

I have owned many subs through the years, even with being a slim, it hits harder than most full depth subs and has great response. I have burned out two of them so buy the warranty, was running with a PDX-M6 amplifier.

Break them in!!!!

i had a set of these i bought for my truck. put them in a sealed box. they worked great UNTIL. magic smoke happen. well i found out about clipping and was trying to prevent it from happening. 40hz for 5 mins is a bad thing. lol yep i messed up. but while they were working i really enjoyed these just break them in. tune your amp correctly these will last you a great while with some great performance.

Good quality speaker wire

Received with my order. Very good quality speaker wire
