I'm so happy, my friend and I finally got it right.
i wanted my bose sub to shut off whenever i put my system on, so instead of my previous 2 switches (1 for bose, 2nd for amp)i got a heated seats switch so now the middle position shuts both subs off,and 1 side turns the amp and the system on, and the other side turns the stock bose sub on.
and it fits perfectly into the provided slot on the bottom left of the steering wheel. finally looks neet.
just wanted to share the joy.
peace

 

please explain to me waht u did to your system? I have a Bose system too and I would like to add a additional Sub in the trunk. please lemme know what you did. the idea with the switch is great!

 

well, the audio shops usually hook systems up right to the back of the radio, me and my friend did a separate switch for the amp,
i dont' really know much , he did all the work, i just ran the wires through the car.
peace
