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 quick-disconnect (not supplied) or
soldered connections. 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).

The wider terminal is the positive and the
narrower is negative (also indicated on the
terminal cover).
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.
