I want to connect some aux. speakers on my deck to the system using a seperate amplifier for the outside speakers.

I don't see any Audio output.

Can I just cut the front right and left speaker wires and then parallel the wires into a Aux Input at the amp.
Or is there another way. I know the Aux input at the amp use coxial cables with the ground wire connected to the outside of the coxial connection and the insulated wire is connected to the inside connections of the coxial connection. So can I do this?
