Great product

Truck guys.. This is the best box out there.

Great for Wranglers

Not build specifically for Jeep Wranglers but I can't imagine a box that fits much better inside the small trunk space. I only wish I had bought 10's!!!

Sounds great in F-150

Put this box in F-150 with 2 8's running 150 watts per sub. Can hear all the bass notes on old rock and roll. No booming at resonant freq. Of course 2 8's don't hit hard but all I need. Used to build my own enclosures but never looked this good. Holds up well not brooken after some had bumps.
