I recently bought a 2009 screaming eagle road glide and had the dealer(useless) install a hawg wired system... amp and 2 speakers plus a hidden antenna, today I noticed that if the bike is in the on position and the radio is on with the volume all the way down I can hear noise coming from the speakers? sounds like a little bit of light crackling and light static? is that the amp causing that? called the useless dealer and the jerk said he doesnt know... he even asked in a smart ass way do you listen for noises? I play my radio at 9.5 and hear nothing? well I am sure someone hear can give me some advice, thanks for looking.
