    • Sounds great fit great. Quick delivery
Size: 12 Inch
Sounds great fit my kenwood subs perfectly and fits my ext cab 06 duramax 4x4 without issue. Seats fold down great. Only downside is not much room for the amp but I was able to make it work. Really sounds good though!

    • 2000 Chevy Silverado Z71
Size: 12 Inch
This box fit my subs perfectly. Better yet, it fit in my truck perfectly. I have had a box in my back seat for 6 years, taking up so much space. Not only did it provide me with a back seat (something I havent had for so long). It allowed me the opportunity to clean my back seat and organize my amp/wires. My setup has never been this organized and neat. If you were worrying about it fitting over the hump in 4X4 trucks, worry no more. This one fits and at a great price. ... show more

    • Perfect!
Size: 12 Inch
I love this box! Fits perfectly in my 02 GMC sierra extended cab. My JL 12" subs fit perfectly in the box. I stapled egg create foam to the inside of box and I am thoroughly impressed with the deep bass from such a small enclosure.

    • Not a bad box
Size: 12 Inch
Husband seems to like these. Although he said the sounds isn’t as good as it was because the speakers are facing towards the floor but having a truck this saves so much room. He had them in the back seat just sitting on the seats and that was a no for me. Overall great product Be sure to measure you’re speakers as he ordered this before doing so and the speakers were to y’all to fit so he had to ordered gap filler rings to make it a good fit and be able to screw them in. I’m pretty sure he’s happy with them ... show more
