Had a buddy just give me his old box and I’ve got to say I’m pretty impressed. I’m impressed enough to come here and write a review on a product that i didn’t even have to buy myself because it brought my subs to life, I will say I’m running this box as an upright behind the seat box in my 1990 c1500 Chevy regular cab and it almost doesn’t fit but it did. Looks and sounds amazing 10/10. I wish Fox Acoustics would design a box for my 1990 c1500 regular cab. A little longer and a little steeper angle on the wedge would be perfect wink wink.
