Still working on tuning the system and getting everything to sound the way I like. I'm only about 4 hrs into the 10 - 20 hr break in period. One thing I have noticed is that even though I deadened the cab, the plastic door covers still make noise from the subs. What is the best way to resolve this? I'm going to try and re-enforce the trim panels and such with a layer of BTX, but not sure how to handle the doors and all their crevasses.
