  1. Start playing some music 
  2. Turn your car stereo volume control up to roughly 3/4
  3. Turn up your amp gain until you hear distortion, then back it off a little

Every amp manufacturer will have specific suggestions, so you'll want to check out your manual for the best way to set the gain on your new amplifier.
