me and my cousin are entering a spl competition this weekend but don't have a box built yet. i know this might be a dumb question but does it matter where you put the port. does it have to be on the same wall as the subs.

it does not have to but normally that yields the best results but of course it depends on the vehicle.. its all a matter of trial and error but if you let everyone know what type of vehicle i'm sure someome has experienced with a design that worked well for it

try facing the subs to the right side of the end of the vehicle... use aero ports facing directly to the back... give about 4-6 inches clearance from the rear wall of the vehicle so u can maximize the effectiveness of the aero ports... have to know the vehicle though and i might be able to change those plans.... muah ha ha ha! DIYers rule!!

4 15" l7s will be loud if you got enough power, imo they are awesome spl subs, i agree with chad on the design also... you should do good if you have enough time to get it all in there... good luck...
