Hmm
If you're pulling that many amps that your revs dip on heavy bass, you should really look into a bigger battery and a stiffening capacitor and probably larger alternator.
My lights dim a little at idle and I thingk I need a cap and tend to go through a battery every 2 years or so.

You might find that your system will kill batteries pretty quickly if you are getting that much drain.

Serious bass is fun though isn't it!!
