Routing Wires
Location and Mounting
The XA amplifiers compact design allows
greater flexibility in mounting. It can be
mounted under a seat or in the trunk.
When selecting a location, remember that
amplifiers generate heat. Select a location
where air can circulate around the amplifier.
Do not cover the amplifier with carpets or
enclose it behind interior trim panels. Do not
mount the amplifier in an inverted or upside
down configuration. Every installation will be
a bit different based upon vehicle design.
Check all locations and placements carefully
before making any cuts or connections.
Important
Allow air circulation around the amplifier.
Important
If wiring connections are made wrong, the unit
will not operate properly and it could be
damaged. Follow the installation instructions
carefully, or have the installation handled by
an experienced technician.
