UPDATE: Added a custom plexiglass window with red LED lighting...

My set up was only $1700 -- all in.

NO. But they had to install the "flat" tire pressure sensors as the others broke off when the wheels turned.

JL Audio System... Ok, I finally got my system installed. I have a 2019 Silverado LTZ Crew Cab with Bose. It hits hard and deep and clean. I did not want to fork out the $1500 for the JL Stealthbox with 2 of their thin 12'' subs. I've always had the W3s and loved their clean deep sound and didn't want to risk being dissappointed with their thin subs. So I did a lot of research and ended up with the following: (PLUS, I saved about $500 overall doing it this way.) I hope this posts helps clarify some challenges/questions.

If you do, you'll see a microphone thing on the ceiling above your rear seat. LLJ Customs can provide you a harness bypass plug as part of your T-harness purchase if you do. I did not have that feature so all I used was the T-harness. You'll need to order a Line Output Converter (LOC) with the T-harness from LLJ so that you can get clean signal to your amplifier. I went with the upgraded "active" LOC -- https://www.audiocontrol.com/car-audio/factory-system-upgrade/lc2i/ -- WHICH LLJ will hook up for you as part of the T-harness purchase. NOTE: You'll need to remove the back seat from the back wall in order to run your wires and install the Lc2i. I don't have a picture of it, but my installer used double sided sticky tape to adhere it to the back wall just to the right of some other electronic box that was alread in there.

I used a long allen wrench to lift up on the hook on top of the locking mechanism which made it much easier. There are 4 10mm bolts on the bottom you'll have to use an extender to reach. Once you get them started, you can remove them by hand. Here are some pics of my install:

Which wiring harness did you buy? Also, which amp?

Bose or no Bose?

Yep. This guy,,,lol. I have a 2019 LTZ with the 6.2l. Zoom in on Hood -- love it!

And it's a big difference over the 5.3 too

Fuel Vapor 20x10

Ride quality is great. Can't even tell a difference really. My wife keeps her Wrangler in our garage.
