Step 4: Working With The Factory Subwoofer Amplifier (If equipped)

Overview
Some Probe Premium Sound systems included a subwoofer and 50-watt subwoofer amplifier. The subwoofer amplifier is located behind the left side rear trim next to the rear seat (opposite the stereo amplifier). If your Probe has the factory subwoofer, you will need to either wire the subwoofer amplifier to make it compatible with your new stereo unit or bypass the amplifier completely.

Option 1: Using The Amplifier
If you plan on using the subwoofer with your new stereo unit, you will need to add a 12-volt signal to let the subwoofer amplifier know when to turn on. Without this signal, the amplifier will remain off and no audio will be sent to the subwoofer. If you chose to use your main factory amplifier as well (Option 1 on Step 3), then no additional wiring is needed. Otherwise, follow the following proceedure.

1. Find the red/green wire on the main radio connector.
2. Connect the red/green wire to the new stereo unit's amplifier trigger wire. If one is not available, connect it to the blue/white wire (main power).

Option 2: Bypassing The Amplifier

1. Remove the trunk cover.
2. Remove the four screws and two push tabs from the rear trunk trim. Pry the trim away from the body to disengage the retaining clips. Remove the rear trunk trim.
3. Fold down the left rear seat and remove the three push tabs from the front, two push tabs from the rear, and two screws from the left side trunk trim.

4. Remove the safety belt trim and remove the hidden push tab.

5. Pry the trim away from the body to disengage the retaining clips. Disconnect the trunk lamp and remove the right side trunk trim from the vehicle.
6. Remove the two push tabs from the quarter panel trim and pry the trim panel away from the body to disengage the retaining clips. Remove the right quarter panel trim.

7. Disconnect the electrical connectors from the amplifier and remove the three mounting nuts. Remove the amplifier from the vehicle.
8. Cut the connector end off both the wiring harnesses and connect the wires as shown below.

Wire Function	Receiver To Amplifier	Amplifier To Subwoofer
Positive	Green	Red/Black
Negative	Green/Black	Black/White

9. When the connections are complete, turn the radio on to test the subwoofer.
10. Reinstall the trim.
