A152-12CP

I was very hesitant when purchasing this enclosure, because I was thinking that there's no way in hell this little box under the seat with the subs firing into the floor would sound good at all. Boy was I wrong, in the biggest sense of the word. What I have. 2 15 y/o Old School Kicker Comp dual 4ohm voice coil VR 12's under the back seat of my 02 Silverado Ext cab. 1 sub being pushed by a Fosgate 300.2, and the other pushed by a Boss audio 1100M Riot (about 250 watts RMS from the Boss amp) with them being set to output around the same power. This box makes these subs slam. It's well made, looks great, fits wonderfully and no rattling. Would absolutely recommend this to anyone needing an ext cab under seat downfiring box. You could not build an enclosure this nice for the $87 (with free prime shipping) that I paid for this. Inside the box along the seams of the dividers didn't have any sealant at all. So as some earlier reviews has stated, you may as well go ahead and re-seal the box upon receiving it. Less chance of rattling and the enclosure ripping itself apart later on. Just call it, preventive maintenance. If you like hard hitting bass, this is it. It arrived quickly, on time, and in great shape.

It won't let me upload a picture but it fit perfectly under my backseat. Nice box. I have a 800watt pioneer amp and it's a little to big to fit beside the box under the seat. So a more slim amp would be better. 2004 GMC Sierra extended cab z71 package. Also, you have to take the terminals out to wire it, it didn't come wired.

This sun box is amazing. I have 2 12 inch Polk subs that came in they’re own ported box, decided I wanted my back seat back so I ordered this and I’m blown away. It hits twice as hard as the ported box and sounds amazing. Fits perfectly under the seat and is very solid. 10/10 would recommend.

Box came a little torn up, but there was no damage done to the box. Got it installed and the sound quality is great. My son is enjoying the system, and is very happy with the sound.

This box does not fit in a 2003 ChevyDuramax

Great product! Great fit! But poor packaging.😔 Luckly I have a 3 door stepside. So the damaged corner that occurred in transit, just happens to be on the side where I don't have a door. So no one will ever see that corner.

Decent looking box, have yet to hear it thump due to misinformation from the questions and answers section. To whom it may concern, when it comes to the dual 12" box for GM extended cab trucks 99-07, or part # A152-12CP, Alpine type r's will not fit depth wise. There will be about a 3/8" gap that needs to be filled. Aside from that, no other complaints, looks well constructed and carpet is great quality, I just expected to be able to plug and play if you will rather than running around town to get supplies to remedy the depth issue. First picture is is the box with cap removed to show the diameter of the sub hole and in blue is the diameter of the actual type r. I'll have to cut it bigger and add a border of 1x1" then add the mdf cap. A little work for big reward but don't tell me it will work when I need to modify it to work......

This product is well received for the price. My main/biggest complaint is that the carpet had started wearing away or even peeling in some spots within a week but with some silicone adhesive was able to get it back mostly to the way it was.
