In a Jeep you need to look for several things to actually enjoy your stereo. The first thing is you need to have a drop-down face. Even with large clouds of dust, a drop-down face will do wonders about protecting your unit from dying in a big dust cloud. This is a bit less successful in a YJ or CJ than in TJs and JKs, but in any of them it works very well. Another thing that is important with your big mud tires, no tops, no doors, and loud exhausts, is the power output. You want the one with the best power output you can afford. This Sony CDX-GT66OUP has the flip-down face and a 52-watt by four-channel power rating.
