hmmm.. I have a cable 1/8" mini plug to a Red/White RCA plug when I hook my MP3 to the home stereo.. so are you saying to split that cable again to hit all 4 speakers?
AND.. knowing that I must unplug the stereo to use the MP3... tempts me to just put the old AM back in the dash and run everything off my MP3..
I'm just into the old hippie stuff that nobody broadcasts now anyways....
