[QUOTE="audiolife, post: 6903065, member: 541383"] I wouldn't run optima for larger systems because they have lower capacity than the other car audio batteries (batteries are a reserve tank not an alt). In general it is also a good idea to jump up 70 amps on your alternator for every 1000 watts rms you add of audio. Example if your car had a 70 amp alt originally and you add 1000 watts rms I would run a 140+ amp alt. I would also check to see if you vehicles have electric load devices in newer cars that pretty much cut out high use of your alternator in the name of saving a few gallons of gas a year. I would also argue that 1500 is indeed alot of power due to the fact if it were indeed doing 1500 watts with efficiency and so forth could be very easily drawing 60-100 amps quite often to music and then actually figuring in the car's needs itself of 30 to 60 amps constantly. Back in the day cars had less electrical requirements and 80 to 110 amp alts with nothing that would cut down an alt to save gas. 800 watt systems would and could be murder on an electrical system and being 20-40% more efficient at 1/3 power doesn't make up for a doubling of power as old school class a/b amps became more efficient when the volume knob was turned up 60-68% efficient at near full power is not as far off from 73 to 80% efficent as a class D is at near full power .
