I'm planning on a Ford nav/stereo to replace the stock radio. I have the basic system, with only four door speakers. If I purchase and install the Ford nav unit, would I be ok with upgraded speakers, or would you suggest a woofer in the back and new amps? I'm not looking to blast the neighborhood. Just improve the sound quality, and add a reverse camera.
Thanks.....
