Harley audio issue
 

I have a 1994 road king that I am running an audio system works fine at idle but when I hit the throttle it cut off then regains power when I release the throttle any suggestions

Loose connection.

i have checked all connections tried a different amplifier re wired it I’m completely stumped on the issue

Maybe repost in the audio forum, lots of audio knowledge over there, just sayn.

Appreciate it
