I have a line output converter wired to the factory subs. Sometimes the audio cuts out and just the subs hit for a little bit then everything comes back on. I think something is shorting. I double checked my wires that I tapped into and they are all good. If I pull the fuse for the radio and plug it back in it fixes it for a little but then it happens again. This never happened before I hooked up the subs.....any thoughts?
