This is in my build thread, but I see guys asking about stereo upgrades so I thought I'd post mine. Just got finished, and it will take longer that you think if you want to do it all right and button it up etc.
I found the amp bracket made for under the steering column online ...and I saw the under the rear seat from @JMT and some others, and read on the double din, I wanted Apple Carplay and I wanted it wireless, so I went with what answered that for me.
So I got a new Head Unit, new front Bezel, a 4 Ch Amp and new wiring and breakers. I put in JBL rear speakers a while ago, and front Polk recently.
Head Unit: Jensen CAR723W with wireless Apple Carplay
4Ch Amp: Alpine KTA-30FW Tough Power Pack
Powered Sub: Rockville SS10P
Front Speakers: Polk Audio DB5252
Rear Sound Bar Speakers: JBL GX6026 (Update 7/1/2025, Crutchfield had Polk DB652 for $79 open box, so I'm replacing the JBL)
Front Amp mount: Taboo Customs TJ Under Steering Bracket
Double Din Bezel: Metra
Amp Power: Skar package with 4awg for rear powered and Crutchfield 8awg amp wiring for front amp.
So I chose a mid priced Double Din from Jensen that had good reviews. My TJ Had a wiring harness plugged in from the Pioneer single din that had been put in by the past owner long ago. I spliced everything in using Posi-Twist for the smaller gauge wires, super easy just twist wire ends and then twist these on.

Larger wires for power I went used shrink crimp etc on the only 2 that needed it going into the Amp harness up front.
I got a nice LEIGESAUDIO 2 way splitter off Amazon https://www.amazon.com/dp/B07KJZK78G?tag=wranglerorg-20
I used 2 breakers for the Powered Sub and the front Amp that I put on the bottom of the Auxbeam bracket https://www.amazon.com/dp/B07KJZK78G?tag=wranglerorg-20

With this head unit I had to bring the gain down as it's amplifying a high output. The Polk sound great, so do the JBL still, but they may get replaced in the future with something that can handle 100w not their 60. They are 6 1/2" speakers, some say don't mismatch because I have the 5 1/4 now up front, but they are component and the tweeter is on the dash, I feel like they match up well. @skrelnik has a lot of radio posts in general, I'm sure his expertise went into my efforts.
Absolutely thunders. I went through a bunch, but Enter Sandman is the one to use for gain setting. It pushes hard. Master of Puppets sounded great, and all the Tool songs I ran through. If it can handle that....I'm good, ha.
