well i decided after countless hour of trying to think i am gonna run 2 15s and 2 audiopipe ap30001d and the sub i havent decided yet but i wanna hit low to mid 150s with subs not e veryone use. so i may not hit my mark and if not i will start over but i am gonna do this with a not so popular sub like a DD but try it with either the hifonics olympus, pa mofo, audiopipe txx15apx, or txxdmz
