I bought a system over the past few weeks. I have a Solo Baric Kicker L5 powered by a 1400 Pioneer Amp. My car won't start because the amp is sucking too much power from the battery. I had to buy a new battery because a cell in my old one died. I feel really stupid driving around with loud door speakers but with no sub. My alternator can't keep up, and I'm hearing multiple stuff from different people. Someone told me that a capacitor would help it, and then others say I need a new alternator. Help?
