[QUOTE="Ken Stewart, post: 602915, member: 62102"] I know the stock alternator is 130 amps. How do you figure how many amps you're drawing? I'm upgrading my stereo system and want to know if my stock setup is fine or if I'll have to upgrade: New system: - Two amps ... one 600watt mono amp running two subs at 300 watts RMS each, one 85watt x 4 running door speakers - Eclipse head unit - Image Dynamics 8" subs (2 ea at 300watt RMS) - Image Dynamics 6.5" door speakers (70 watts RMS) Plus, whatever the XLS model ST draws without the aftermarket stereo. Also, who knows the gauge size of the stock wiring ... may have to upgrade??? Thanks ... [/QUOTE]
