IMPORTANT: 

Make sure the 

subwoofer amplifier is turned OFF before 
setting the SSI switch. Do not change the 
switch position while the subwoofer 
amplifier is operating. Doing so could 
damage the amplifier.

CONNECTING THE 
AMPLIFIER

The subwoofer connectors are compatible 
with bare or tinned wires. The 
recommended wire gauge is between 
14AWG and 8AWG, depending on the length 
of the wire run between the amplifier and 
woofer. Heavier gauge wire is preferred 
for runs over 6' (2m).

1.Use a 2.5 mm hex driver to open the 
connectors
2.Insert the wire ends into the connector 
openings
NOTE: If using untinned bare wire, be sure that 
no stray “+” and “–” strands touch each other. 
Touching strands can cause a short-circuit, 
which can damage your amplifier.
3.Use the hex driver to secure the wires in the 
connectors, as shown in the illustration
to the left

1. Use hex wrench to open connectors
