well in width at the tightest area is 45 height at the lowest is 35-36 and depth 26 thinking of doin a wall so i can put my battereis and amp rack behind the wall. your honest opinion would you go with 4 type r 15s on at least 3krws or 1 solo x 18 i am gonna put one or the other in a wall so i dont have to switch out boxes and just use a drop port

I'd do 4 15's with a 3kw amp.
