Hi everyone. I've been trying to run a speaker level signal wire from the rear subwoofer in my HK system to an amplifier the past few days but none of the shops I took it to was able to figure it out without taking apart the entire rear dashboard which would take 4+ hours.

Anyone have any ideas to how I can run a simple signal wire to the amp from either the rear speakers or the factory amp or anywhere else?

Thanks
