Amp problems on Harley 2012 FLHX

[freebird00yea@yahoo.com]

Bazooka MC-HD-AMK 4-Channel Harley Amplifier Kit . Installed and used with no problem on my 2010 FLHX. Installed it on my new 2012 FLHX with success until one day right turn signal began operating on its own a random times. Could hear a popping thru the speakers with radio off and power switch on with signals working. Disconnected amp and hooked up original factory harness and problem went away?? Dealer was scheduled to look at problem and during checking for codes is when we noticed popping. They were perplexed by problem but glad I was able to unhook the amp and not them to charge me a diagnostic fee for aftermarket item installed. Anybody ever heard of this or ran into it?
