Spent the last couple days installing the Retrosound head unit/amp/sub. Everything appeared to be working fine until I took a test drive and the one thing I didn't test was running the A/C while the radio was on - when I switch the A/C blower on the radio turns off. Further detail - power is coming from a dedicated line off the battery (yes in-line fused) through the firewall (via the ignition wire grommet) to a distribution block (one line goes to amp, which in turn feeds head unit, and one line goes to power the subwoofer.) Since nothing is in the way there I don't believe it's the hot wire. Next the switched line is connected into a purple wire/connector, which I believe is the dedicated factory radio connection (this is where the dead Blaupunkt in my car was connected.) It is grounded through the dedicated ground line which I believe was also for the factory radio. In my wiring diagram it looks like this ground eventually runs back to a load shed relay which is also connected to the blower motor (pins 30, 85-87.) Before I open everything back up just wondering if this is causing an issue and I'm losing ground and just changing the ground point would fix it, or if there's something I'm missing.
I do not have the original blower switch as it died, I wired in a 3 speed switch with resistors on the back, in case that's useful.
One other question while I'm at it - what is the quickest way to test if the antennae works - when I yanked the Blaupunkt out the power antennae wire was never connected. I know the trigger wire is low amperage so I didn't want to hook something up that would fry it. The coax was connected to the radio so not sure what was up there.
As an aside, there's barely enough room to get a small amp behind the glovebox, the only reason I was hellbent on doing that and not under the seats or something was because the Retrosound stuff has a plug-n-play harness which is not all that long and I wanted to avoid having to run lines all over. Sound quality is very good although I used Hertz speakers since they fit my old 70's-looking speaker enclosures so I can't vouch for their speakers.
