INSTALLATION CONSIDERATIONS
• Installation requires appropriate tools and
safety equipment. Professional installation
is recommended.
• This product is water-resistant.
Do not submerge or subject to
high-pressure water spray.
• Before installation, turn off the audio
system and disconnect the battery
system from the audio system.
• When possible, install in a dry, well-ventilated
location that does not interfere with factory-
installed systems. If a dry environment
is not available, a location that is not
exposed to heavy splashing may be used.
• Do not install in the engine compartment,
any areas of extreme heat or where it will
be directly exposed to the elements.
• Before cutting or drilling, check for potential
obstacles behind mounting surfaces.
• Carefully route all system wiring away moving
parts and sharp edges; secure with cable ties
or wire clamps and use grommets and loom
where appropriate to protect from sharp edges.
SAFETY CONSIDERATIONS
• Only use this product with 12 volt, negative-
ground electrical systems. This product is
not certified or approved for use in aircraft.
• Mount this product securely to prevent
damage or injury in severe conditions.
• An appropriate fuse (or circuit breaker) at
the main power wire is vital for vehicle/vessel
safety and must be installed within 18 inches
(45 cm) of the positive battery connection.
• For ABYC and NMEA applications,
circuit protection is required within 7
inches (18 cm) of the battery, unless the
cable is in an enclosure or conduit.
• Listen to your audio system at
levels appropriate for operating
conditions and hearing safety.
