Usually, my volt meter is steady at 14, whenever the bass hits, it drops to twelve. I have been keeping the system off today, and so far, I haven't had a prob starting it, however, once I turned the system on (even low) my volts drop, then if I keep the rpm's up, it will go to 14, then to 12...

Stock alternator in my GSR is 90 amps...a friend said I should be running an alternator making no less than 240 amps to supply my audio system, vtec controller, add on gauges, et etc...

This is oh so annoying because my system sounds sooo...unbelievably good.
