I've never found any good subs for them except for amps with rail voltage lower than ±70v. For those, I use the IRF3415. I've tried some of the NOS SSP45N20As with mixed results (mostly bad).
i was going to change them all because its pushing and pulling the subs but this amp is weird so im trying not to blow it up.but that would be the cause of that right?
it was doing this in the car the person had it in he didnt know what he was doing i haven't played it i just checked everything since the person was already in it. but he had three amps on a crappy ground,and on one cross over that was not set. would that cause it?
