Hi brother, do you mean I need to add the Ground Loop isolator between the radio unit and the amplifier? is this the ground loop isolator you describe? The previous owner of my GS300 cut the line of amplifier, I tried very hard to re-connect them all, but i found that, there are so many noise when using the amp, I i think this should be the tricky part as you said. As my after market radio don't have RCA output, it is like this: can I cut the RCA plug of the Ground Loop Isolator, and just connect the signal line of the isolator the the radio unit and amplifier? Thank you very much.
