Denis, thanks for the feedback. Sort of confirms my earlier concern...
So, I did as "theesotericone" pointed-out in that one thread and located that black/white wire. Quite easy with everything apart now...
I temporarily hooked-up the stock amp and radio and I was able to confirm that this wire is indeed antenna power:
I added about a foot of wire onto each cut end and it's now ready to receive a switch. I plan to mount the switch in the bottom left cubby. Those switches arrived today and feel quite nice. I wrapped the wires back-up with some friction tape...
There was a lot of dust back there, so I spent a fair amount of time cleaning-up with damp paper towels and a vacuum.
I permanently mounted that 74 bulb base that I had added in the cigarette lighter location.
I mounted the tweeters. I will wrap the speaker wires is various spots to protect against abrasion and also support the speaker wires for strain-relief reasons. I'll likely do that tomorrow...
I began scoping-out a location for the amp. It should indeed fit in the factory amp location. I'll probably zip tie it in place, after I confirmed all works well, and I have the desired settings. I recall that I will likely want full gain to those Infinity front speakers, as an example...
I did some theft deterrence today as well, which I won't go into detail here.
I aim to also check for cross-over locations tomorrow too. Inside the kick panel would be nice, secured so not rattling. [MENTION=143526]theesotericone[/MENTION] - On these cross-overs, do you recall if you pressed those "+3db" buttons?
I decided to remove the cargo privacy screen or whatever it is called. When we go on trips, it will likely just get in the way most of the time, and take-up valuable space. Also, when used, I somehow feel that a thief will be more inclined to want to break-in, thinking that it is hiding valuables. For anyone who cares, it's exactly 8 pounds.
I looked at the back-up camera cable I had routed a couple weeks back and it has three wires. The video line with RCA to the HU, red (power) and black (ground). I'll probably do switched power and incorporate both (red and black) into the Metra / HU crimp work to come...
I did look briefly for that red/yellow (will silver tick marks) reverse wire to trigger the back-up camera, but did not see it. I will look more tomorrow, which is when I should get that parking brake bypass...
Once everything is done, working well, I suppose I should get the doors back to how they looked before - with the vapor barriers?
I have some pretty thick mil sheets of plastic (clear) that I can cut to size...
