With music the 200A alt should be more than enough with a solid battery or two backing it up.

qft. The only time you'll see max current draw is at a given frequency at it's max output, split seconds in time where you may clip the amp, unless your blasting rap at full volume all the time you'll be ok, just no 2hr airforces marathons.
