Radio wont power on ive tried everything!!!!!

I own a 06 jeep grand cherokee and I'm pretty knowledgeable when it comes to installing stereos or any electrical related problems but I can't figure this one out. About a month ago I was installing a new battery and connected the wires backwards for a few seconds. After correcting the issues immediately and hooking up the battery I realized my radio wouldn't power on. I just assumed it was a fuse but it's been over 2 months and I still haven't figured it out. I have checked every single fuse and the amps in ALL 3 fuse boxes. I pulled checked and replaced them all 1 by 1. According to the fuse box diagram the 20 amp fuse in the power distribution center under the hood (F28) controls the radio which I discovered was blown was replaced. I then just assumed the stereo was fried so I just purchased a used after-market sony explode CD player and installed it double checking everything and I still can't get any power to my radio! I'm out of ideas and this is really starting to frustrate me! PLEASE HELP ME!!!!!!!

-CHECKED AND REPLACED FUSES IN ALL 3 FUSE BOX'S 1 BY 1
-REPLACED STEREO
-CHECKED WIRING

Welcome to the forum.
I moved this thread to the Grand Cherokee forum section where your fellow WK drivers can best assist.

If all else fails, use a multi-meter or test light to verify voltage leaving the fuse and again at the stereo. That'll give you a better idea which direction to look.

Ok. I've got a multi meter but I'm almost positive there is no power going to the stereo. I've ruled out fuses (trust me) and it's not the stereo itself.. What's next??

If you've ruled out a problem at the fuse panel, then you have power leaving the fuse but not making it to the radio. Fortunately they're not too far apart which narrows the problem down quite a bit.
A good ground is as important as a good power feed, but of no help if no power reaching the radio.

Well keep in mind that this happened because a battery was connected backwards for a few seconds so that might help narrow it down a bit hopefully? What should my next course of action be or is it almost worth taking it somewhere to get looked at?
