I have a '23 xlt and recently started upgrading the system. I started with the kicker key 200.4 amp with stock speakers. It was a massive improvement and I thought what the hell and ordered the kicker 6.75" and 4" speakers and it sounds even better. I went ahead and ordered the tweeters last...
I just put the kicker key 200.4 amp in with the plug n play kit wiring harness, it was pretty darn straight forward and I was nervous because I'd never done anything like that before. Made the stock speakers sound so much better.
