As the topic says I got a 16.5 cube total wall and got 4 15" sa-15's to go in, any suggestions on what should be done with port size and tuning?, I have 2 ap3000d amps to power the subs. It will be for daily and if possibly a hair trick would be nice..
The vehicle is a 97 z71 ext cab truck with the box being 17" deep .
Lmk what ya'll think
Thanks
