if using the rear outputs from the
source unit
• Connect the rear outputs of the
source unit to the rear inputs of
the crossover. Slide the parallel
input switch to the “OUT”
position.
if using the subwoofer outputs from
the source unit
• Connect the subwoofer outputs of
the source unit to the sub inputs of
the crossover. Slide the parallel
input switch to the “OUT”
position.
AUDIO OUTPUT AND POWER CONNECTIONS
• Connect the high pass and subwoofer outputs of the XM series
crossovers to the inputs of their respective amplifiers.
• Connect the crossovers’ B+ terminals to the positive terminal of the vehicle’s
battery. Cut the supplied fuse loop (so there are now two separate wires
that attach to each end of the fuse holder). Install the fuse holder 18" from
the battery on the power wire that runs through firewall or sheet metal to
protect the battery, the vehicle and more importantly, you.
• Connect the GND terminal of the XM series crossover to the vehicle
chassis. For better conductivity, if necessary, scrape paint off of the
chassis to reveal bare metal at the contact point.
• Connect the REM terminal of the crossover to the remote output
terminal of the source unit to establish crossover remote power on/off
via the source unit. If the source unit does not provide a remote output,
connect to its power antenna terminal.
• Double check all the previous installation steps. If everything is in
order, complete the installation by reconnecting the battery ground to
the vehicle chassis.

WIRING
Caution: Routing audio cables and power cables together would invariably
cause radiated engine noise in your audio system. If possible, run audio
cables on one side of your car and power cables on the other. Never route
these wires underneath the vehicle body.
• It is best to route all wires of the audio system along with the existing
electrical wires of the vehicle through this would call for the dismounting
of kick panels, door sills, etc. Where possible, the cleanest and safest
route is under the carpet or behind the side panels.
• If you need to dismantle any part of the vehicle during installation,
make notes of the dismantling process to ensure that you would be
able to reassemble those parts afterwards. All the hardware, for example,
screws, dismantled from the vehicle should be kept in a container to
make reassembly easier.
• Run the various wires accordingly while avoiding sharp edges and
door jams.
• Grommets should be used to protect the wires when they are routed
through bare metal holes. For best protection, we recommend using
automotive flexible plastic tubing, and for ease of handling, use plastic
tie-wraps.
• All wires and cables should be “stress relieved” at various points on
both the input and output side of the crossovers. Cable clamps should
be used to reduce stress on the terminals.
Note: The battery ground should remain DISCONNECTED at all stages
of installation.
AUDIO INPUT CONNECTIONS
• Connect the front outputs of the
source unit to the front inputs of
the crossover. If using the XM2’s
speaker level input connection,
use the appropriate speaker wires
from the source unit.
• If using the XM4 with source unit
that does not have additional rear
and sub line level outputs, slide
each parallel input switch to the
“IN” position and skip the next
two steps.
