I want to add a amp and a sub to my truck. I dont want to lose my factory head unit. Can it be done. HOW???? I really dont want to change the look of the dash. Plus I have On-Star and dont want to lose its functionality.

Is there a way to tap into the head unit and get line level output for running a sub amp?

My sub amp has a built in low pass filter and sensitivity setting and accepts both left and right channel inputs, so I just need a clean line level signal from somewhere to feed it.

Since I have a crew cab, I'd rather not pull my signals from the speakers in the doors via speaker level -> line level adaptors.
