I have a good idea what i m doin but am not experienced so what should I do. I have 2 kenwood 600 watt amps and not enough power for both. I just got an optima yellow top and that didn't fix the problem. I am ordering an 180 amp alternator will that be enough? Do I need caps? If I do what should I get? I am tryin to get my subwoofers finished so I can move onto sumthin else.
