does the Ipod have a docking station with RCA out? as far as I'm aware it only has the normal headphone socket
in which case your kinda of limited unless you get fancy with your wiring
and if i was going to use an MP3 player as a stereo replacement it certainly wouldnt be an Ipod in the center of some nice speakers... but I'll refrain from the "Ipods suck" crap because someone else will do it later
all I'm saying is the DAC in them aren't too good and wouldnt reccomend decent speakers for them...
