How Many Amps?

Good stuff.

Have you checked all of your wiring and connections. I would check the output of the altenator at the batt. and at the alt. to see if there is any deviation between the two. If there is then you know you have a weak wire or connection somewhere.

yeah vile but if you run 500 watts on a 20 amp fuse your gonna starve the thing your trying to run so thats why i say 10amps to 100 watts at least thats the rule you go by running cb equipment

 A 500 watt load at 14 volts would pull about 35A so a 40A circuit would be required.

Bear in mind, unless you're dropping wads of dough on Tru's steel or billet line, your "500w" amp is probably only driving with about 150-200 of those watts, even peak. Tru and Arc Audio are the only two brands of stereo amps ever made that I would trust to be putting out anything CLOSE to their RMS values..

Research the CS144 alternator swap. Check out MADelectrical.com LOTS of great info there. I have done thhis swap on ALL of my Chevy trucks and LOVE it.
