i have a 99 camry with two 12 inch mtx 9500"s with a 2500 watt kicker amp class D. and i had two car batteries with a 0 awg wire for power from my front battery to my back battery. and i found out that my small 40 amp alternator couldnt power my two batteries, therfor my car died last nite with two dead batteries. i need to beef up my alternator or something. i need help. also i heard that i cant just get an after market alternaor cuz i will have to re do my belts and pulleys to fit the larger part. what can i do?
