I remember you. You bought the twin piston AE92 calipers with the 275x25mm disc's off me.!!
Anyway, about the amp, I dont know if its the competition one. All i know is, its a great amp. It ran my kenwoods really good, and it also ran my friends Competition Pioneer 12inch easily. According to HOT 4s under $500 amp test, this amp came 2nd to the 2x200Watt Jaycar response amp in terms of power. Its the AC2500 to be precise. It pumped out 78x2WRMS or 214x1 WRMS at 14.4Volts (If that means anything to you)
