I have a cadence zrs-9000d that went into protect, then shut down completely on me. No light (red or green) comes on anymore. I'm not sure what happened but I don't wanna fool around with it. I was pushing two treo ssx's at .5 ohms. It has worked flawlessly for the 10-12 months I've had it. I'm looking for a big enough amp to push ONE of my ssx's. I'll add $ if necessary. Pics coming soon.
