The AW128t is the highest of the flame compression series, the only sub that audiobahn makes that has a higher power rating then this one is the IMMORTAL so i would say this should be pretty high end, i think anyway....about the alternator thing yea im planning on grabbing one, with 1 stock and one yellow top batteries if i can grab them. Amp still deciding, i have a XX Colosuss comming via UPS but the **** thing only fits in one spot on my car, looks cool in that spot but dosnt leave much room for any other ideas (3200 RMS BTW). Second idea was to get a US AMP that pumps the 2000 RMS since i herd there stuff is underrated i might be getting almost full potential, but i need one that can be wired in 2 Ohm mono since thats what my subs are... Havnt checkd yet but my buddy told me they do have one and i got a dealer who can get me US AMPS for cheap
