Also, would it be worth it to upgrade the head unit to something with GPS or go ahead and buy the stock gps/nav unit from jeep?
To be honest, if you are looking for a subwoofer there are two routes to proceed with. The first, get the JL Audio Stealthbox or the second, get a custom sub from a install shop. If you read other post's in the forum, the number one complaint is the factory sub lacks bass.
As, for the a HU, an aftermarket gps HU are much better and if you can wait the new generation of HU with faster processors are coming shortly.
Very important, make sure the installer can handle the high speed can-bus system the Grand Cherokee uses.
Best for now.
