CnadianFF Posted February 18, 2014 Report Share Posted February 18, 2014 I just installed a Z150BH, at low volume I can here what sounds like a constant ground loop. I have tried to ground my HU chassis to vehicle chassis, I also tried grounding my HU chassis to the rca ground no change. Could this be the Pico Fuse? Does this HU have the Pico fuse problem? I have read Pioneer has addressed the issue, is this true? Thanks in advance. Quote Link to post Share on other sites
skittlesRgood Posted February 20, 2014 Report Share Posted February 20, 2014 No, these avics dont have a pico fuse. they use a protection circuit. I seem to have more noise with the avic than I did with an alpine nav. Just have to chase down the source of the noise. Could be wiring, could be an amp, could even be your alt or spark plug wires.
