Dads radio is in at Wards right now getting repaired...its an am/fm and getting the "aux" jack...I asked them about upgrading it to stereo...they said $459 please...I said no thanks....oh he also said dont try splicing the one speaker wire into 2, you will short/burn/blow something up in the circuit board...fyi
