I realize this is a very old thread, but I recently got a 2004 Ford Explorer, and I installed my aftermarket Pioneer deck.
Currently, I'm about to install an aftermarket sub and amp to the system, which I know how to do...but I was wondering how if any of y'all know how I would be able to install the 8inch sub/amp that was stock with the car into my deck as well? Right now the wiring harness for the stock sub/amp is just hanging loose behind the deck.
Will I need to wire it into the RCA cables for my aftermarket sub/amp before plugging in to the deck?
TIA!
