A big alternator will over charge a small battery and reduce battery life.

A 944 and a MRD1000 should be ok with a 75amp battery.

I suspect the Pio woofer will not be able to asorb 1000W without hitting it's Xmax even in a 1cu ft. sealed box in a ported box it will hit Xmax even earlier. so in effect either you are getting a lot of bass distortion or your Alpine amps is being underutillised. besides the MRD puts 1000W in 2 ohms but if each amp is only driving one sub then it is going to be be limited at 500W / 4 ohms (about 11A continous each).

I'd change the Boss wiring. remove the Boss caps (as suggested by JB) and check.

lastly if you got 15,000 songs in a 30GB ipod your compression ratio is definitely not good enough. I'd suggest looking at EAC and LAME and hydrogenaudio.org for more info on how to rip good quality MP3s.
