I think my amp has gone out. I called a local HD stealership and they say : we need to run diags on it $91. If the problem does not show I'm liable for the $91. He also stated if there are any aftermarket stuff warranty will be void. I hear popping in the speakers with the connectors out of radio and with radio off also. Heres the problem. I have wired in the XM modules as shown here . It has worked flawlessly for 6months, I soldered the can connections on the ipod module side of the connection, I them connected the other 3 wires from xm connector into the large connector on back of radio. I have removed the xm mod from circuit but had to use shrink tubing to cover solder joints,, Will they void warranty for hooking up their boom audio components?? Anyone tried a warranty claim with the extra boom audio connected?? don't know which way to go.
