Okay so I'm getting closer to doing my wall build I'm excited! My interior has been stripped for a month, been working on doing 100% coverage of sound deadending mat. I have also spent countless hours looking at ALOT of awesome, informative builds everyone has on here. And. So attempting to design my own box and find the air space to fit these junk 12s in a big tuned box in the back of this truck, I was wondering what if I just completely fiberglasse the extended portion of the cab and mounted a vented baffle? Is it even possible?
