Bbox Dual Sealed 10 Inch Subwoofer Enclosure - Accu-Tuned Subwoofer Box Improves Audio Quality, Sound & Bass - Fits 1999-2007 Chevrolet/GMC Silverado/Sierra Extended Cab,Charcoal

I have a 2000 Chevy silverado, 3/4 LS extended cab, and was very worried about the fit because of the little room for error in measurements. While searching many stores for a fitted box specific for my truck, the prices were very high. I found this and ordered it to because I could not even come close to the price anywhere else. The box arrived in a timely fashion. I inspected it and it was sealed and very sturdy. I installed a pair of 10" majestic subs and slid it right in place. Very happy.I recommend this box to everyone, it hits hard, sealed, and very sturdy.

This box is absolutely perfect. I put it under the back seats in my 2000, GMC sierra 1500, SLE. It houses two 10" Pioneer subs and the combo between the two 10s, this box, and the 1000watt boss amp is amazing. Even with my amp down, and the bass settings in the truck down, all the seats can vibrate, and so can windows. Now trust me, this isn't the annoying and stupid sounding bass you here from the trunks of other vehicles. This box can help deliver a solid deep bass tune that is perfect for anybody who wants a system in your truck.

Fits perfectly and looks stock mounted 2 Alpine 10" type R's and they sound great well worth the money.

It fit nicely. I can't comment on the leg room part because I took out my passenger seat as well as the back seat to change my carpet from faded worn brown to black. But the speaker box looks good and the two JBL 10" subs I put in it sounds great.

Box works great. Sounds amazing. On down side was the terminals. Plastic piece on the back side was rattling like crazy. Little epoxy fixed that issue. Fits perfect. I'd give it 5 stars if I didn't have to modify anything.

For starters I ordered the box for an 06 silverado extended cab. When the box came it I didn't fit but I have a v shaped hump in the middle no big deal there mistakes happen when ordering online what really pissed me off was when I called about it they said I was doing it wrong along with that's what it supposed to fit and then hung up I then have called countless times and never hear back. They took my money and don't care that it doesn't fit and refuse to try and make it right. Box wasn't in great shape didn't fit the subs and didn't fit in the truck.

Box arrived with next day shipping and no damage at all. The speaker clips are a bit cheap, but they held the 14 gauge speaker wire that we were using with no issues. If you are thinking of running in parallel - there is a divider board so there is no way to connect the subs within the box. You have to do it outside the box.Overall - very pleased, no air leaks and this box with Alpine 10" subs down firing being powered by a Kenwood KAC-7005PS (subs in parallel) hits hard.

Fits perfectly under my back seat. For the people on here that say it sounds like crap... you have to realize that you're pointing your speakers at the floor, of course it's not going to sound as good as a speaker box that projects the speakers into the cab. This box isn't for premium sound, it's for the thump, get better speakers for your doors and you got yourself a good stereo system.My only gripe with this box is they didn't have a speaker wire tail on the quick connects to hook to the speakers, had to remove the quick connects and install my own speaker wire tail, but wasn't that big of a deal. Ten minutes and had the speakers installed and in the pick-up thumping away.
