I have an after market pioneered 7" deck and full hids. Yes I have the relay harasses and 10 second delay relay for my lows and my sensor is blacks out so no DRL.. Anyways, 90% of the time when I turn my fogs or highs on or switch back to my lows from high beams it will stop my ipod from play for about 5 seconds then it will start playing again. It does this with iphones as well but not with cds, dvds or the radio. The only thing I can think of is trying to ground my ballast to my frame. I have a red top and a 50 farad cap and my big 4 are upgraded to 0 gauge as well with my power and ground wires for my system so I know I'm getting enough juice. Interested in what you peeps think is going on. I can deal with it but its just kind of annoying.. Not to mention I'm worried that's its being hard on my ipod.
