Alternator Gauge Reading High With 300 Watt Stereo System Installed---1969 Electrical System

Thanks for the detailed info. I'll borrow a meter from my friend the next time I'm over at his shop and see what kind of numbers I'm getting.

I have a 6 gauge cable running directly from my battery to the amp(with a fusible link in between).

Another friend who is good with stereos mentioned a capacitor, but he said that's only if the amp is cutting on and off or dimming my lights when bass hits at high volume. Neither is happening. My lights dim slightly at red lights because I have my idle turned down a bit, but that was happening before the system.

I'll start with the meter and go from there. Thanks a lot for your input. You guys are always a wealth of information.:thumbsup:
