My '91 Integra is trying to run a 550 watt Alpine 5 channel amplifier and is burning up alternators.

It is my understanding that the car is rated at 60 amperes. That is just not enough for this powerful Alpine and the A/C, Lights, etc..

I am going to beef up the grounding cable and replace the alternator with a High Output alternator...say 150 amps or so.

Am I on the right track here?

Thanks
