Okay so I've been working on my 1991 pickup build. And if you familiar with the truck you know they lack space for subs. I've always like the bass response in ported boxes over sealed. I'm new to box building. And tunning looses me.
First question: what is a good tuning hz number for ported box
Second question: how would I be sure I'm making the box with the right tuning?
Also. If I posts of some size restrictions I need to stick to would someone be willing to give me a design. I wanna put one sub behind each seat and put the port in the center between the seats.
