Three cables need to be removed from 

the amplifi er assembly: (1) negative 

(yellow and black) cable, (2) positive 

(solid yellow) cable, and (3) led PCB 

cable.  Do not force cable removal or 

connection, although needle-nose pliers 

may aid in gently removing the woofer 

cables.  Notice their placement, as well 

(see following 3 pictures).

It may be easier to remove the amplifi er 

assembly if the cabinet is on its side.  Do 

not completely remove the amplifi er 

assembly yet, as the cables need to be 

removed fi rst.  

   

Caution:

 The amplifi er assembly is 

approximately 23 pounds, so please 

make sure to grasp it fi rmly.

The terminal for the negative (yellow and 

black) woofer cable is located towards 

the bottom of the amplifi er assembly, 

close to the transformer. The cable must 

be attached to the same terminal it was 

removed from. Failure to do so will result 

in greatly reduced power.

The terminal for the positive (solid yellow) 

woofer cable is located near the center 

of the amplifi er assembly, just above 

the four capacitors (dotted above). The 

cable must be attached to the same 

terminal it was removed from. Failure 

to do so will result in greatly reduced 

power.
