1.  Disconnect all external cables; lay the subwoofer on a padded surface so the grille is facing 

upwards.  Remove grille. 

2.  Remove the (4 each) #8 x ¾” woofer mounting screws to remove the woofers; the woofers may 

seem “stuck” to the cabinet.  Carefully pry each woofer rim away from the cabinet with a wide flat 
screwdriver, taking care not to mar the cabinet surface. 

3.  Unplug all speaker wire connectors from the woofers. 
4.  Turn the subwoofer cabinet around so that the amplifiers and controls are now facing upwards. 
5.  Remove all (12) #8 x 1” mounting screws from each amplifier heatsink. 
6.  When attempting removal, the amplifiers may seem “stuck” to the cabinet; if necessary carefully 

lever the heatsinks away from the cabinet with a medium-sized screwdriver blade, using a dowel 
or plastic screwdriver handle as a fulcrum.  Take care not to mar the cabinet surface.  See 
illustration. 

7.  Remove both amplifier assemblies partially out of the cabinet and rest them on the cabinet 

surface. 

8.  Pull the speaker wires up and out of the cabinet; these may be re-connected to the woofers or a 

4

Ω

 resistive load during testing, depending on preference. 

9.  No additional connectors need to be removed and amplifiers can remain connected as-is, this 

should be sufficient for most servicing. 

10. After completion of service, thread the speaker wires back into the cabinet *, insert the amplifiers 

back into their cavities and replace all screws; re-insert, re-connect and and fasten both woofers.  
Replace grille. 

11. Test  unit. 
 

 

 
 

 
*  When re-connecting speaker wires, it’s not critical that a certain pair of wires connect to a certain woofer 
(since both black wires and both white wires are in parallel); however, there is one longer set of wires that 
should be matched up with the woofer that is furthest from the connection point.
