I have a unique problem related to my amplifier/ speaker setup. With the engine running, the speakers hooked up to my amplifier emit a constant "popping" sound & are heavily distorted no matter the volume. However, with the engine completely off & the electronics running solely off of battery power, the system sounds great. I have the amplifier's power & ground running directly to the battery on separate terminal bars so that they're not in direct contact with the main harnesses.
I've ruled out the RCA's going from the amplifier to the head unit & have tried a ground loop isolator with no luck. The amplifier is brand new & I only recently noticed this issue when I had my boat out for the first time this past week. Has anyone experienced something similar or have any recommendations on where to go from here? Should I re-route my grounding cable to a different location on the boat? I'm open to all suggestions. Thank you!
