Im looking to add an amp and sub in my 2006 Chevy TrailBlazer. Im looking to keep my factory radio. I do have a bose system. I know I need a line out converter. Wat I need to know is where I could get at the speaker wires to get a signal from to hook up to the line out converter. And wat colors they are going to be.
Also where would be a easy place to get the switched 12+ volts from for the remote wire.
