H3 Radio calibrated VERY QUIET

[MJS H3]

Hey guys. My radio is suddenly very quiet. I need it on MAX volume in order to hear it at medium volume,

Also, the "ding ding" noise that reminds you your lights are on, etc is whisper quiet.

does anyone know how to calibrate this?

That is strange indeed. Could be a blown fuse!?

hmmm. Try disconnecting the battery for a minute and see if it resets. Could be radio or amp going out. Might have to take it in for service.

Good idea and worth a try. If it doesn't work, head to the dealer. That is something I have never heard of, but might be a simple programming issue.

:iagree: but that is assuming you have a factory head unit.
