It's not easy to get the tune of f8.9 bit right...

There is a downloadable configuration tune file on the Audison website, but it is pre-configured for a hi-fi system only.

I downloaded it and did VO Code on my car to Hi-Fi system (SA 676).

At first I noticed that it was working fine. ok, but it didn't turn on my external subwoofer APBX 10AS (channel 9).
I entered the configuration and noticed that in this setup there was no channel 9 pre. And then the madness started... Because the output channels cannot be reconfigured after the setup wizard is finished.
I did a lot of testing and compared the configuration binary files (in hex format) and that's when I was able to redirect the rear subwoofers from the original configuration to the front/underseat subwoofers and add the rear subwoofer on channel 9 pre.

This took about 2 hours or so. But now I have something very satisfying.

is final tune attached.
