Okay I have a friend building me a 4th order wall in my 98 dodge extended cab. I have 28 cubes gross. Subs I'm going with are sp4 15's or 18's. And a ampere 7500.1. I don't want this to resolve in talking me into a flat wall or anything else. I'm wanting the loudest musical/daily. Not sure if 2 18" sp4's will be best or 3 15" sp4's.
