Ever since I have installed my new sub with LESS power from the amp I was using previously, My car has not been starting up every now and then. I have tested both the battery and alternator they are both fine. I'm floating at a 12.6v and I'm sure that's good, so I really cannot figure out what the problem could be. It seems to start pretty easily after I give it a jump. What do?
