MTX Thunder Elite 801D Mono subwoofer amplifier 800 watts RMS x 1 at 2 ohms
I bought this amp with a set of TR7512-22 running at 2ohm's in a ported enclosure. All I have to say is WOW. I was using the TR5512's and thought that this amp would power them nice, it did till the TR55's coils got hot. With the peek of the amp (1600watts) you have to make sure your subs will handle the peek.
