HOW TO WIRE / FUSE YOUR
SUBZERO TO AN AMPLIFIER
The Subzero subwoofer
comes equipped with 2
voice coils (dual 2x4
ohms), it can be used in
2 , 4 a n d 8 o h m
configurations. The
terminal comes equipped
with fused jumpers, the
voice coil can be easily
configured in series or in
parallel to match the
amplifier in use. It is just a
simple flip of a fuse,
here’s how it works.

The diagram -on the left side- shows
the PSP terminal in a 2-ohm parallel
configuration (both voice coils are
connected in parallel). Simply place
the 2 fuses in the outer positions in
the fuse placement area. Insert the
negative speaker wire to the far left
insert and one positive to the far right
insert.
This diagram shows the PSP terminal
in a 4-ohm configuration (the two
voice coils are separated). No fuses
are used in this configuration,the voice
coils are powered up separately.
The diagram - on the right side-displays
the PSP in an 8-ohm mode. You will
notice that there is only one fuse in
the center of the fuse placement area.
The voice coils are wired in series.
Insert the negative speaker wire to the
far left insert and one positive to the
far right insert.
