Unfortunately, just having an aftermarket DD head unit in the dash is a dead giveaway. And in my experience, if you have an aftermarket stereo in your vehicle and the thieves know it, if you make it really difficult to remove they will just trash the interior of your Jeep out of frustration, which will end up costing way more than just replacing in the stereo.
As previously mentioned, hide all of the equipment as best you can and make whatever you do have visible as OEM, cheap, and generic looking as possible. Print "Kraco" stickers or badges to put on the speaker grilles, "Pyle" or "Boss" stickers on the amps, etc. Cover everything you can with deep black carpet or grill cloth.
And never leave ANYTHING on the dash, seats, floor, that may pique the interest of would be thieves. Except to put a baby seat and open package of diapers and fake dirty diaper in the back with a baby bottle & toys everywhere. Thieves hate working around baby stuff for some reason, LOL. Yeah, your friends might give you strange looks and comments, LOL.
If you still have the OEM stereo, cannibalize it and make a fake faceplate from it. Or buy a dead OEM Jeep stereo from eBay. Recess your aftermarket DD Head Unit in the dash if possible and place the fake faceplate in the opening when parked.
You can see how I did this for my GF's SUV in the link below because she had to drive and park all around Hollywood and the L.A. area to meet with clients, often in some sketchy areas, unfortunately.
I cut out a piece of 1/8" Masonite/hardboard to the overall size of the faceplate bezel and epoxied it and all of the loose buttons, knobs, and LCD panel that i removed from the donor head unit to that flat backing board. Then I attached a few small felt cabinet door "bumpers" to the back and covered the entire back with Tesa Tape so it wouldn't scratch the Kenwood's touchscreen.
You'd never know there was nice DD Kenwood XR head unit in the vehicle..."Nothing to see here, move on"! Details and photos in the Link...
hey there, just picked up a Sony CDX-C90, cosmetically it is in great condition. Haven't hooked it up on the bench yet to test functionality. I am currently running an 80prs with the Sony XM-5046 amps. I knew it was going to be a project getting familiar with the C90 and components. I have...
