The F150 truck has been manufactured by Ford for over 60 years. In 2006, although Ford offered different trim levels, most F150s included a four speaker stereo system with in-dash CD player. Expanding the stereo system to include an amplifier will allow for the addition of a subwoofer or aftermarket speakers that are able to produce better sound. Installing an amplifier in a 2006 F150 is a relatively simple procedure due to the RCA pre-outs located on the back the factory stereo.

Determine the location where the amplifier will be mounted. Secure the amplifier in place using an electric screwdriver and the provided mounting hardware.
Remove the plastic trim piece surrounding the F150's stereo. The trim piece is held in place by metal clips. Gently pull the trim piece away from the dashboard to release it from the clips. Remove the four screws holding the stereo in place using an electric screwdriver. Slide the stereo away from the dashboard until you are able to see the wires. Do not disconnect any wires.
Locate the blue accessory wire coming from the rear of the stereo. Remove a small section of the wire's protective plastic coating using wire cutters. Wrap the bare end of the matching wire from an amplifier wiring kit around the bare section of the stereo's accessory wire. Wrap the connection in electrical tape covering all the bare wire. Run the blue wire through the dashboard and down one side of the F150 to the amplifier. Attach the wire to the accessory wire terminal of the amplifier using an electric screwdriver.
Attach the red power wire with the in-line fuse from the amplifier wiring kit to the F150's battery using the provided hardware and a crescent wrench. Make sure the in-line fuse is located next to the battery. Run the red wire through an existing hole in the F150's firewall, through the dashboard, and down the same side of the truck as the accessory wire to the amplifier. Connect the red wire to the power wire terminal of the amplifier using an electric screwdriver.
Connect the RCA cables from the amplifier wiring kit to the RCA pre-outs on the back of the truck's stereo by pushing them together. Run the RCA cables through the dashboard and down the opposite side of the truck than the power wire. Connect the RCA cables to the RCA plugs on the amplifier by pushing them into place.
Slide the stereo back into the dashboard. Secure the stereo using the screws removed earlier with an electric screwdriver. Press the plastic trim piece back into place. Reattach the negative battery cable using a crescent wrench. The amplifier is now installed.
