As of now (until I tore if all out) running 4 fiaudio ssd  18s, skar 4500, 4 deep  cycle batteries, mech man 320 alt, pioneer 5a head unit, a bunch of 0gauge , custom ground bar.  Going to 2 mech man 320 ,8 group 31s ,8 18s, 2 skar 4500s strapped, and wanting to wall /4th order style it all. Starting thinking clam  style or something but trying to get ideas abut what would be the best for these subs and most efficient.  And of course loudest.
