Question about Kicker (ZX750.1) Car Audio Amplifier
SOURCE: No power output
Set the meter to AC volts and measure the AC voltage on the RCA cables where they plug into the amplifier. The black meter leat will go on the shield ground of the RCA cable. The red lead on the center conductor. You may have to turn the volume up to get a reading on the meter. At high volume, you should read at least one volt but the actual voltage will vary due to the audio signal. If you get no voltage on the RCAs, measure the AC voltage on the input to the LOC. Let me know what you find.

I would say that your subwoofer Or speaker leads have shorted out...when the bass hits as you say it drives the amp hard but if it is trying to dump power onto a shorted speaker or speaker wires it will blow the output power transistors not to mention other vital components of the power amp...i suggest you test your speaker leads with a Multimeter on the ohm setting before connecting a repaires or another amp.. to make sure there is no short on the leads and that the resistance is around 4 ohms or so depending on how you have your drivers wired...but anything lower than 2 ohms will cook an amp! you can normally pick up a meter from anywhere for around $10..
