MTX 3512-04S 12" 600 Watt Shallow Car Subwoofer+Sealed Sub Box Slim Enclosure

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.

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:)

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

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 :)

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.

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
