well i still am unsure of the right thing to do. so skip the big 3. cuz i was thinking it was the alt. like u said befor. nor will a battery really do anything. the battery just starts the car and then the all mighty alt takes over. if i was playing music with the car off then a battery and big 3 would be good for me. so lets say ok i need a alt. i dont want like 200 amps what should i get. i have had people help me but as far as saying ok joe this what u should buy. some links ,names of compaines , places to check out thats were i could use some help lead me to the right alt for my car.
