Replacing a Subwoofer Amplifier

Tools Needed:

• #2 Philips Head Screwdriver
• Small Flat Blade Screwdriver

***Make sure amplifier is unplugged before proceeding!!!***

Allow the capacitors to discharge after unplugging the amp for 15 minutes before touching any internal amplifier components. 

1. Remove perimeter screws
   

   *Pictures provided are for example only; amplifier panel may vary slightly by model.

   
2. Once the screws are removed, give the amplifier panel a good tug to break the gum seal holding it in position
   
   
   Note: Feel free to use a small flat blade/tool to help you gently pry the amplifier panel away from the cabinet
   
   
3. Once the amplifier panel is removed from the cabinet, use a small flat blade screwdriver to release the wire clips holding the positive and negative terminals of the amplifier panel 
   
   
   
   • Note: These are push-on connectors. However, to detach, they may have a slight locking "clasp" in the middle of the connector. A small pair of pliers or pressing the tip of a small screwdriver into the middle of the connector should unlock this "clasp." Alternatively, these push-on connectors can be detached from the cone woofer

4. If the subwoofer has an LED indicator light on the front, a wire which runs to the LED will also be visible once the amplifier panel is removed
   
   
   Note: This should be a "clip-on" connector. There may be a small tab that you will need to push on in order to release the connection.

5. Remove the LED wire and plug it in the exact same position on the replacement amplifier panel

6. You will also now need to use the two wires that lead to the cone woofer and plug those in on the replacement amplifier panel. They should go in the exact same position that they were in on the previous amplifier panel

7. Once all wires are in place, screw the replacement amplifier panel back into the subwoofer cabinet to conclude the replacement process
