You only have 4 speakers, 2 at the front (L&R) and 2 at the rear (L&R). What you think might be Tweeters are just for show and don't exist. :>D

A bad connection at the speaker or the unit could be a problem. Burned out amp section as well.
This may help.

They vary. Most Yukons and Tahoes had standard 6" (or 5-3/4") front door woofers and 1" tweeters in panels on the door switch clusters in 2-door models, and in 4-door models, those plus an additional pair of 6" (or 5-3/4") 2-way speakers in the back passenger doors, and in 2- and 4-door models with the premium sound package, they also had 4X10 oval speakers in the rear roof by the cargo door(s). These 4X10's were 3-way speakers.

You should remove the relevant door inners and inspect the connectors to the speakers. They corrode easily being close to the outside. Sometimes a wiggle will get the speaker working, otherwise you will have to crimp on some new connectors.

On my 99 4 door the factory amp is powered by a hot pink wire in the truck harness. I hooked the cont. power for a motorized ant. to it and all 4 speakers work. I'm going to check today to see if they work correctly because I found this out late last night and only had it on for a few minutes. I've read that there is a harness for this that apparently you have to specifically ask for at a car audio shop. hope this helps.

check wiring on passengers side near the rear hatch speaker, the rear door speakers are run through them also. i had the same problem and it was a unplugged connector at that location

Chrysler in their goal to make a buck put splices inside the rubber tube between the door and the a pillar on later Cherokee's. This is to spit the harness between the main door speakers and optional tweeters.The plugs for the tweeters will be there no matter if you have them or not. These connectors make the wires more susceptible to breakage. Have a stereo shop rewire your front speakers.
