I sent a feedback a day or so ago because I just finiished installing everything,I actually went look earlier but didn't see it...anyway..this box is very well built and sounds extremely good, I have 2 Skar dual 2ohm subs in it..sounds amazing, fits extremely well, I would recommend this company 100% as I had purchased a box last year from another company and it didn't fit at all..I was directed to Fox Acoustics by someone who also builds boxes, I have a 2005 Silverado crew cab. Extremely hard to find a box for this truck..let fox build you one,you be glad
