has anyone put one of these boxes in a mazda 3 sedan i just got a wild hair in my @$$ and instead of having the manual specified box i want my H.O. box in my car. i havent measured yet just seeing if anyone has done it. just eyeballing it i think im gonna have to do some trimming and bracing. im not worried about the body if i do cut it i have access to a frame rack and measuring system. maybe someone has made some better boxes that fit i just dont like the sound coming out of the manuals box compared to H.O.
