  • Perfect fit and well made!!
Size: 12 Inch
Perfect fit!!! It's made to fit exact. I was hesitant to buy but looks professional and fits great. Sound is decent for a down firing sub. I'm really pleased. Highly recommend

  • 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

  • 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.

  • Sloppy fit
Size: 12 Inch
I didn't like having to modify the box because the holes were too large

  • Subs do not sound good since they mount upside down and hit the floor.
Size: 12 Inch
Box is nice and fits good but the subs sound horrible. I put my rockford fosgates in it and they sound horrible. Barley can hear them. since the subs sit upside down they have no room to flex and they just hit the floor of my cab. selling the box and putting them back in the original box.
