    Some of these vehicles have an amplifier under the center console if your vehicle is equipped with one. The radio, amp., and wiring through the door jamb is the only thing that two speakers have in common. If you do plowing with your truck you may have corrosion in the connectors at the door speakers if these are the two not working.
