10. After 10 minutes, unlock the vehicle.
11. Turn the ignition On.
12. Test to ensure audio is playing.

NOTE During testing, with the back of the seat removed, you may hear slight rattling-the vents on the back wall cause it. The change in air pressure will make the vent flaps move, mimicking a rattle. With the seat installed, this rattle will not be evident.

Reassembly

After successfully testing the system, you can begin reassembling the truck’s back seat. Depending on your truck’s model, you may need to modify the rear seat to allow its reinstallation in the vehicle. Look over the instructions below to determine which steps to follow to reinstall the rear seat.

Back Seat With In-Seat Storage

TIP If you have a seat back that opens to the storage compartments, you can remove the foam from the back seat, and the inverter can be mounted to the amp board without requiring any additional modification.

Back Seat Without In-Seat Storage

If your truck has a rear seat without in-seat storage:

1. Cut the foam on the back of the seat to accommodate the amp board installed on the back wall. The area to cut is highlighted below.
2. Cut and test fit so that you only remove what actually needs to be removed.

3. Once you have cut enough foam to ensure the seat clears the amps on the amp board, you can install the seat back into the vehicle.

NOTE If you have a Back Seat with in-seat storage, you can mount the inverter on the amp board and install the seat.

WARNING If you have the Back Seat without In-Seat Storage, you cannot mount the inverter to the amp board. You will need to find a location behind the seat to store it. There is room on the driver’s side, and the factory wiring is long enough to accommodate the move there.

4. The white weather stripping can be removed, trimmed to length, and reinstalled onto the modified seat foam.
5. Reinstall the (4) 10 mm bolts to secure the back seat.

6. Move the seat belt anchor plate and buckle into place. Using a T-50 Torx screwdriver, screw the retractor plate back into place and connect the electrical connector.

7. Install the (6) headrest mounts back in place, and install the headrests.

8. Reinstall the trim pieces on the passenger side, including the B-pillar and front passenger door.
9. Reinstall the vehicle jack under the rear passenger seat.
