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 and 8ohm

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.
