[QUOTE="kross, post: 3202358, member: 577729"] Hmm, after blowing the fuse 3 times, the amp has probably had enough. Just out of curiousity though, what kind of load were you giving the amp? How were the sub(s) wired? How many subs? DVC or SVC? Anyway, you can check a few things. 1. Make sure the amp is getting power. Set the DMM to measure DC voltage. Black probe on ground, red on + to the amp. Should be over 12 volts. Same thing with the remote turn-on. 2. Make sure the amp is getting signal from HU. Set the DMM to measure AC voltage. Unplug one of the RCA's, and make sure it doesn't touch any power wires while it's out! Put the black probe on the outer shield of the RCA, and red probe on the center. With music playing, you should see a fluctuating reading of about a volt or so. Plug the RCA back in. 3. Measure the output. Set the DMM to measure AC voltage. Remove the speaker wires from the amp, and measure the voltage output at the speaker outputs. Black on -, red on +, for the speaker output. It should be fluctuating, several volts. This should help you narrow down the problem. -- Kevin [/QUOTE]
