finally finished my speaker install this weekend, new head unit wired up, steering wheel controls working fine, reverse camera connected and working, but the display isn't switching to the camera automatically when I go into reverse, still working that one out. antenna also goes up as soon as the car is turned on, not just when I'm actually using the radio, so need to work that out too.
sound deadened both doors with stinger roadkill, makes a huge difference to how much outside noise gets in. i'm assuming it helps with the speakers a little too, but I didn't do a before/after to compare how it sounds.
new splits installed in the front, and all wired up nicely, without molesting any factory wiring in the doors or to the factory tweeters. sub install behind hte passenger seat is also pretty clean I think, no visible cables, but it's a bit annoying now not being able to put the seat all the way back. building a smaller sub box might be a future project.
this was my first time doing any car audio installation so it was a big job for me, overall it seems pretty easy, but I found the documentation and instructions lacking specifically around steering wheel controls and reverse camera install.
next up i'll need to spend some time tweaking the settings to get it dialed in nicely.
have taken the jack and winch out of the back of the car for now, will have to figure out where to store it now. probably room for the jack and winch behind the drivers seat instead, if I can make sure it doesn't roll around that should be fine.
