What kind of wattage are you wanting to run? My stock alt is only rated to 105 amps, I've heard of cars with 75 amp alts running without any problem, with systems that run about 600 watts to the sub and 75 watts to each mid. It also depends on what colume you listen to your music at. At low volumes, each channel is only using a few watts, or even less. Remember, following a speaker's sensitivity, just one watt of amp power provides over 85 db of sound, which is high enough to hurt hearing over a long period of time. At those normal listening volumes, any amp won't tax your electrical system. If you need power for competition burps, add a battery to store power for them. Unless you're running massive amounts of power, a class D won't save you a measurable amount of electrical current.
