One of my friends has 2 Audiobahn Dual 4 Ohm Subwoofers in his rx-7. He got a JL 500/1 amp and after trying to hook it up and it not working he was told to wire his subs in parallel. Tonight we wired them in parallel and when he turned them on they would thump but between tracks the subs would continue moving in their own steady beat. After that we took them and hooked them up like they were before and now they won't work like that either. Anyone have any ideas?
