I have a 2020 Equinox with the IOR radio. I bought an integration harness with an Audiocontrol LCQ-1 pre-wired. Once installed, I had no output from the LCQ-1. Weird thing is: My speaker voltages are between 0.2v - 1.1v which seems low. However, the radio works fine with this voltage but it just isn't enough to juice up the LCQ-1 to integrate an amp and such. The radio gets good and loudish with decent clarity. I truly don't think anything is broken., GM service information does say "...between 2-10 volts" but my radio works fine. I feel like it's suppose to be putting out this "low" voltage.
I've tried in line resisters and about 50 other things. It's worth noting that when I measure the voltage on a speaker output with the STOCK configuration, I get about 1.0v at 80% volume. When I measure the voltage on a speaker output with the integration harness in place, I get about 1.0v at 80% volume.
