How to Install a Non-Factory Radio in a 1998 GMC Jimmy

Installing an aftermarket upgraded stereo in a 1998 GMC Jimmy can be accomplished with minimal tools. If you are intending to upgrade the Jimmy's radio, pick one with 50 watts per channel or higher. Radios are sold by total wattage that must be divided between the number of speakers. A 200-watt radio has 50 watts per channel. Many aftermarket speakers can handle more than 100 watts of power.
