Alternator Vs. Amps
right now i run a 750W RMS system in my car, i was wondering if that would be too hard on the alternator? should i get a beefier one? how much can the stock alt. handle does anyone know?

All the 2 litre Protege's come with an 80 amp/hr alternator. To figure out the load, add up all of the accessories and subtract from 80. Whatever's left is the juice for your system. To figure out how much power you need for your system. Add up the amp. rating from you amplifiers, that's how much power you need to run your music without draining the battery.
Keep in mind though, that these numbers aren't static: the system will draw more power the more the accessories are going (eg. a/c, fan, stereo, windows, lights, etc.) In addition, we don't know where the 2 litre Proteges make that 80 amps, is it at idle or under power (eg. around 3000 RPM)?
Also, how do you usually play your music? Your amps won't draw the full ampere rating unless they are at max. power.
Hope this helps.

I'm pretty impressed with having an 80 amp alt in our cars - I was expecting like a 65 or so. 80 is not bad at all - oh, and the alt seems to put out decent power at idle, too, because my dimming is only slightly worse at idle than it is with the engine revving 3000 RPM+
Don't waste your money on an alternator - use it to buy 700 more watts of power (well, then maybe you'll need the HO alt - what a quandry, huh?)
