American Sound ConnectionCompatible with Chevy C/K Silverado or GMC Sierra Full Size Extended Cab Truck 1988-1998 Dual 10" Subwoofer Sub Box Speaker Enclosure Carpet

Didn’t fit under seat like I expected but its ok

It worked and fit but for the skar speaker I used I had to add 1by1 wood around bottom to keep the speaker from hitting the floor board.

Its like someone built this thing based on how they remembered the back seat of a chevy looked like. sticks out from under the seat about 2 inches. Sits too low, so you have to put blocks under it or your subs are hitting the floor.It doesnt even sit on the floor properly. All that being said, it does work decently. Im going to see if i can somehow put it behind the seat.

I would give it a 5 star if it was a little bit thicker I had to get smaller subs with a shorter magnet.. overall good quality and sounds good 👌

1997 GMC K1500 Ext. CabThe quality is par for this price point. The carpeting in a couple of areas wasn't tight in the corners and was splitting, but honestly, I couldn't and wouldn't do any better in those spots that won't ever show anyway. The part of the box that faces out is what they pay attention to and it looks fine, and the questionable parts... well, those are some tight angles.I did have to do some trimming, as you can see in the photo, to the area where the subwoofer gets screwed down. The mounting ring on the 12" Rockford-Fosgate R2 was just a little to large of a diameter to allow the sub to fit flush. A utility knife whittled away at the offending portions of the box, no sweat.My 500 watt Rockford-Fosgate single channel amp fits in the short step of the box beautifully, and after test fitting the box, I noticed I could mount my 3 Farad capacitor to the inside edge (where it looks like it is sitting on top of the box in the photo), although only two of the four mounting screws could be used, but no matter, she's tight ;)The box is made well, all visible seams inside were sealed and after mounting the sub, it gave that satisfying thud, when tapped. All in all, you will be happy. I have yet to finish the rest of the build, but will update if sound quality stinks, but that is highly doubtful. I had this setup in another vehicle, different box, and it crushed. Buy away boys, it'll work!UPDATE:Sound is just fine. I haven't checked for air leaks, just tuning the amp and head unit now, but the sound quality is very good. Note, I did have to remove my capacitor, it didn't quite fit as hoped. omitted the cap entirely from the system. I turned the amp so the terminals faced the passenger door (Not the rear of the can, as in the photo) and it wired up easily. It is doing everything it is asked to do :)

Fits great on a 1998 GMC Sierra ext cab. Just sticks out a bit doesn’t sit flush with seats

Fit under the seat very nice. Only draw back was had to widen speaker opening. However rather widen the opening instead of having it to big. Good value, I would buy again

This is a solid box for your 12" subwoofers. The craftsmanship is very good. Seems just a bit thinner than 3/4" MDF. I doubt it will deform, though.Here's the trick. You need 11" cutout and less than 6" depth on those subs to fit this box. For 12" subwoofers that actually ties you down to some limited purchase options. I ended up going with a pair of  Kicker 40CWRT121 12" CompRT Car Subwoofer  which are more shallow than they need to be, and every other dimension fits this box, including the trim ring not overlapping the standoffs. The other limitation of this enclosure that the Kicker CompRT's respond to well is the volume. This box only offers .95 cu feet of air. The CompRT subs only ask for .55. There aren't a lot of other subwoofers out there spec'd for less than 1 cu foot of air.I deduct one star in my review because I think those standoffs are unreasonably close to the cutouts. They could have been cut to allow larger trim ring subwoofers to be installed.In case anyone is wondering, I've got a  Rockford Fosgate Prime 1,200-Watt Class-D 1-Channel Amplifier  powering those two Kicker CompRTs. Sounds great with this enclosure.This box sticks out about 3.5" from under the rear bench seat in my 1996 Chevrolet K1500 Silverado. Please see pic.
