The proble im have with this one is if the Rca jacks are plugged in the amp draws 25 amps of current... If i leave them unplugged the amp powers up and idle's about 2 amps of current...
I'm not familiar with this amp but I'd expect to see 0 ohms between the RCA shield and the non-bridging terminals. Look for a broken connection on the RCA jacks or an open trace.
Hey. I've got two working Hifonics Gen X Thor amps sitting under my desk if you have any questions. I believe these amps are very similar. Also, if you get this amp fixed and are in a position to sell it please let me know. Thanks!
