Now I am a little pissed off here. I am dealing with a new audio shop that is close to home instead of the one that did my initial install and I went over it with him what I discovered about my box being too big. He said he saw it last time but didn't want to say anything... but agreed to help me fix it today. Since the sub is centered he is lopping off about 6" on each end to give me 1.0 cubic ft. He said it should play tighter but may not be as loud.
While I was there he stripped the carpet off my box and then what was under it had me upset. It was just glued together! No screws, no liquid nails and still had build garbage in it! This guy is going to fix all of that for me while fixing it. He said eventually it would have come apart! I will never go back to that shop again. On my truck project I want to attempt doing the entire install from beginning to end including building my own box so you guys may get tired of me asking questions but how else will I learn.
