Your amp is drawing a lot more current when the bass hits.  Try getting
a more powerful alternator.  40 amps ain't shit.  My 81 VW has 65. 
Your best bet though would be to get a cap (preferrably 1 farrad) and
place it across the power wire to your amp, and ground.  Unless your
system is all that, 1 cap should be enough to keep the voltage up where
it should be.  If one don't work get two.  They go for about $100 each.
They will also probably make the bass hit even harder.  Letting the
voltage of your electrical system frequently drop below 12 volts is a
sure way to toast your voltage regulator.
