What part are you looking at? More specifically, what type of audio output does it have?
Sure you can. If it has a typical 3.5mm jack (headphone plug), get you a 3.5mm to (2) RCA cable and an amp that recieves rca input. The best sound quality... I don't know.... I would guess you could get stereo hooked up but without fade, and it would not be "optimal" sound (as if it existed in Jeeps anyway).
