So somehow during the reinstall of my Tuffy center console I managed to screw up the stereo. No output from the head unit. All fuses OK and indication that she's alive. Clock works CD loads, volume & signal indicators, etc just no audio. There is some sort of "cigarette pack sized black box" on the firewall that the speakers are all wired to. It takes a signal from the head unit to power up. It "click's" when I turn on the stereo, but again no audio.
Wired a speaker directly to the head unit speaker wires and got no audio.
Thinking about scrapping the whole thing and replacing. NOT looking to go the whole sub routine. Just looking for good sounds through the speakers (dash, soundbar and rear 6x9's).
