Right now I have my 3 Kicker Comp tens in a sealed 1 cube per chamber box (pictured in my sig). I am thinking about porting these and wonder if I should make all 3 subs same chamber and port it or seperate chambers. Should I use round ports or slot port and how much cu ft shuld I need for all 3, and what size port. Any suggestions would be appreciated. The box sounds very good and I have had it installed for about 1.5 years, just wanting more output. My old setup was 1 type r 12 in a slot port box and it was louder than these, but these are a lot better sq wise.
