I have 1 Audiobahn 15" AW1571T sub, w/dual 4 ohm voice coils. The rating is 500 rms, which I belive is 250 rms per coil. What would be a good amplifier to purchase? I have been told to get an audiobahn A8000T by auduobahn, but yet crutchfield audio advisors tell me to get a MTX thunder 421D for my sub. Their reasoning is that the A8000T doesn't handle a 2 ohm load as well as the A8000T. The 2 ohm load of course would be if i wired my sub in parrellel. Your relpy would be very helpful.
