Installation Considerations

The following is a list of tools needed for installation:

This section focuses on some of the vehicle considerations for installing 

your direct fit subwoofer. For the purpose of this manual, the vehicle shown 

as reference is a 2014 BMW X1. Other vehicles may differ depending on 

model, year and options. Consult your vehicle’s service manual for model 

specific information.

Under Seat Subwoofer Replacement

• Ratchets

• Torx screwdriver / bits

• #2 Phillips Screw Driver

• Pick or small blade screwdriver

Step 1 - Seat Removal

Remove the bolts that hold the seat track to the floor.

Once all of the bolts are removed, tilt the seat back to provide access to 

the subwoofer.

Do not unplug the wires under the seat. Doing 

so could generate a WARNING light on the dash 

of the car and require a trip to the dealership to 

get cleared.

Step 2 - Subwoofer Cover Removal

Remove cover to expose subwoofer.

Step 3 - Subwoofer Removal

Remove the screws that hold the subwoofer in place. Lift the subwoofer out 

of floor pocket and unplug the factory harness.

Step 4 - Subwoofer Installation

Plug factory harness into the new Rockford subwoofer. Place the new 

subwoofer into floor pocket and use the factory screws to mount subwoofer.

Step 5 - Reinstall Subwoofer Cover

Once you have the subwoofer plugged in and mounted securely, reattach 

the subwoofer cover using the factory screws.

Step 6 - Reinstall Seat

After you have the subwoofer cover installed and secure, place the seat 

back down onto the floor. Tighten the factory bolts to manufacturer’s specs.
