I Recently Installed A Jl500/1 And A Line Output Comverter In This Car, And Weird Thing Is .. When Amp. Turns On The Fm .. Reception Goes Away.. Rally Weird.. Tried All Basics .. Regrounded Amp.. Ran New Pwr /gnd Outside Car And .. Tried Other 12 Volt Supply From Another Source, New Line Out.. Its Just Wehn The Amp Turns On The Fm Signal.. Goes Away.. Really Weird. I Have No Idea What Is Causing This.... And One Other Thing When You Touch The Amp.. Its Acting As An Antenna.. The Recption Comes Back In When You Touch The Casing Of The Amp Itself.. If Anyone Can Explain Or Help.. Please Anything Would Be Good..
