500 max or Rms? If it's a 500 watt rms amp, and class D, then it will probably have between a 40 and 50 amp fuse rating. You may be ok with your stock alt, and then agian you may not. I have no idea what your alternator is rated at. I'd say if you have a 100 amp or more alternator, you should be ok. If your amp is 500 watts max, then you will be fine with a smaller alt.
