Aftermarket Stereo Install - With pics!
I have been searching the forums looking for some good aftermarket stereo install pics in a 2011 JK, but have not found anything...so here's a go at providing some information that may help everyone.
STEP ONE: Remove the dash panelIf memory serves me, all the screws are 7mm
I'm not going to post shots of this because many people have already done it. I can tell you that there are 4 screws to remove BEFORE you try to remove the dash. (2) Behind the "snap-out" panel below the steering column. (1) Underneath the "junk tray" at the top of the dash. (1) Behind the power window switches in the dash.
(Don't forget to disconnect the electrical connector them. Just slide the red tab, then pinch the connector and it will release. You can see the connector in the pic below)
Once you have these screws out, simply pull on the dash toward the tailgate. Once out, you should see this:
Take out the four screws that hold the stock stereo in. You’re gonna have to find these on your own. If you can’t find them, you’ve got trouble…
Pull the stereo forward and release all of the connectors. The standard antenna and satellite antennas have some interesting connectors. You can lift a small tab on them to release them. Here’s an OK shot of the antenna connectors:
Contrary to what many posts indicate, you DO NOT have to cut anything behind your dash. You can pull the metal bracket that will get in the way of a double-din stereo install by removing (2) 7mm screws.
And she’s out!
