I have been trying to figure this humming for weeks. I have a 2010 ultra limited with 4 6.5 hertz up front powered by a sound stream Picasso nano pn4.520d amp in the back I have 4 hertz 6x6 powered by a diamond 2v2 amp and a aquatic head unit with a dsr1. Bother amps are connected to the battery both positive and ground. Have had the system for years worked great. Then one day I was walking my bike in my gravel driveway then my speakers started crackling and humming. Cracking in only with bike running but the humming is with it off. I have 2 speakers at the backseat that are powered by the radio alone. They are fine no humming or cracking. I have checked everything I can think of checking so I’m back to square one checking everything again. So any help you can give would greatly be appreciated.
