I have two 4ohm svc 10" audiobahn subs wired parallel to a mono hifonics BXi 1206D amp and my amp will turn on but the subs aren't hitting period. Where should i start to diagnose the problem? Maybe the fuse?
if amp turns on and the subs are not working at all, then wither the subs are wire loose inside box(if you have them wired together in box, or wire loose from terminal from inside box) blown sub or subs,or bad rcA or the output of amp is blown. I would check wires first, then i would try 1 sub at a time on the amp or if you have a speaker that you know is good, put it on the amp,SEE IF IT WORKS
