Need to know how big of an amp would be safe with a 90 amp alternator


Unregistered guest
Hey I was wandering that if 1 Memphis 15" sub and a 1200 watt amp would be too much for my 90 amp alternator? I have no power windows , power locks, power seats etc. so wouldnt the car only be using up about half of the alternators power? thinkin about adding another 15 too and was going to turn the power down on the amp so that I wouldnt be running too much juice to the subs. Tips please

Yes. The amplifier (if 1200 watts RMS, class D) alone would pull 100 amps of current. :-) And power windows seats etc arent using power unless they're in use anyways, heh...
