FuzzFace2 Posted November 25, 2017 Share Posted November 25, 2017 Premium Sound meant there was an amplifier, small as it was. The wiring was different for that, like the info I posted. I don't think this had that system but again this was all from my parts truck and the radio/HVAC control panel was removed (partly ripped out) so I don't really know.
