Has anyone used this amp, Sony XM-D1000P5? Here are the specs:

500 watts RMS x 1 at 4 ohms
900 watts RMS x 1 at 2 ohms
Class D design
50-300 Hz low-pass filter, 12 dB/octave
bass boost (0-10 dB centered at 40 Hz)
speaker- and preamp-level inputs
gold-plated connectors
requires 4-gauge power/ground leads wiring and hardware not included with
amplifier
13-5/8"W x 2-1/8"H x 13-1/8"D


I have a S12L7 that I need an amp for. I was also looking at a Rockford
Fosgate 501bd...which one would be better? Or does anyone have any other
suggestions.


Thanks,

Shane
