I just finished up a double din install in my 2002 Suburban Z71 put in a Pioneer AVIC-X930BT.

It had a non-Bose system with subwoofer and rear seat audio controls.

The dash bezel modifications went a little better than expected and I got everything working just fine.

Today, I decided to remove the slave cassette and replace it with the console pocket. With the cassette unplugged, I don't have sound through any of the speakers so I currently have it plugged in and hidden in the console.

It seems as though the cassette deck is acting as some kind of audio pass-through. Anyone know of a solution where I can take the cassette deck out?

I did not test the factory radio with the cassette unplugged. My tests have only been with the aftermarket radio and cassette plugged/unplugged. There are two 9-pin plugs in the radio compartment. The one originally connected to the factory radio is unplugged and the other plugs in near the original radio wiring harness. I did swap those to see if it had an effect. Nothing worked when swapped.
