Great power from the gods

I Just installed one of these amps playing 2 sets of pheonix gold 6.5 components and let me tell you this amp rocks!!! Becareful though, if your speakers can't handle 85watts rms @ 4 ohms this amp will easlly fry them , but if you got good speakers, then be ready for a loud ride.
