ok right now i only have one sub working but when i plug in both RCA cables to the amp then they both move alot but sound like crap. its not the amp cuz one will work even if i unplug one of the cables from the head unit. so right now i only have one RCA cable plugged in. i was wondering if it would be the head unit.

well each sub works on its own. i can have the left one work or the right one work but not both at the same time. i had the same problem with my other 12's but i got a new headunit and they worked fine then i blew them and bought new ones and now i have the same problem again.

are the subs in separate chambers or is it one big chamber with no divider? probably subs out of phase. swap the output wires on the amp for one sub only and see if that fixes it.
