I just hooked up dual battery setup for my rzr with isolator. I also installed switch with relay to power my acessories so I could power with ignition off. Everything is working good except when I turn the switch off I get a popping noise coming from my speakers. I never had this when everything was hooked into factory distribution block under the hood. I had amp power hooked directly to battery and remote on hooked to acc power. Now I have both remote on and power hooked together. Any suggestions to try would be great.
