Im trying to figure out what type of amp these are that i have found. The guy im buying them from is at work, and he has 2 of these amps. he is running them on 2 Alpine type R's, and they are beating the R's pretty **** well. Both amps are at 2 ohms, and he says the subs are getting 1k each at the 2ohm load. What model could these amps be from the the Phoenix Gold line??? I thought about the xenon line, but they didnt make a 800, just a 600 and 1200. Anybody have an idea what model these amps are!!!
