I plugged in the Jazzy/PAC GLI last night and sure enough, I'm getting cut out issues with my Belkin Auto Kit. I pulled the white cap off the Belkin and the chip inside does get quite hot. If I play the Belkin at about 1/4 volume and the HU at 20+, it doesn't cut out very much, but it's still annoying. Plus, I would like to have the HU at a similar volume to where I would listen to the radio just in case I want to listen to a traffic report or something. I guess I'll have to either try the heat sink idea, or go back to a straight cable and deal with the ground loop noise (which I only notice on soft songs with low volume).
