J & M AMP Problem Please Help
Hello All Heres the problem When you rev the bike up the amp goes in to protect mode and shut off.When bike comes back to an idle amp comes back on.Background i vie had the amp for two years no problems last winter i had a set of 12in apes put on.i got the bike back no problems,I HAD TO HAVE THE BARS REPLACED due to a small defect in them.My guy put them on once Rode the the bike 30 miles no problem,i go to pick it up and its doing it(also throwing codes for my ecm) so he rewires the bars this time he soders the wires puts it back in and no codes for my ecm BUT the amp is still doing the same thing.PLEASE HELP.PS the ground for the amp is a 10 mm self tapping screw to the frame of the bike,we also tried to ground to battery but made difference.

usually when an amp goes into a protect mode:
overvoltage- check the voltage at the battery
shorted speakers ( wires)
open speakers (wires)
with music playing & motor off shake the bike, see if a speaker wire is shorting

You have a loose connection somewhere or a wire going to ground. That is why the problem is only happening when you rev the bike up.
Check all of your connections, and look for bare wires where the insulation may have been rubbed off.
