-Microphone Bracket Installation-
A metal clip is provided for mounting the microphone. Choose a
location convenient to the operator and away from any air bag
deployment areas. Using the mounting clip as a template, mark the
two holes to be drilled. Using a 1/8” drill bit, drill the two mounting
holes. Install the two #6 screws provided with the bracket.
WIRING:
WARNING! All customer supplied wires connecting to the
positive terminal of the battery must be sized to supply at least
125% of the maximum operating current and FUSED at the
battery to carry that load.
Ensure the amplier / relay unit is mounted in dry, protected
environment.

WARNING
!
Do not install this product or route its wires in
the air bag deployment area.
Doing so may cause damage to or reduce
effectiveness of the air bag, or create projectile
that could cause serious injury or death.
To determine air bag deployment area refer to
vehicle manufacturer's manual.
MOUNTING
-Amplier Installation-
Before drilling holes, check for clearance to prevent
damage. Check both sides of the mounting surface
before drilling and the be aware of any vehicle
components or other vital parts that may be damaged
during drilling.
Install grommets in any wire passage holes.
1. Slide ¼” hex head bolts into amplier t-slots.
2. Place mounting brackets over bolts.
3. Thread ¼” lock nuts onto bolts and tighten down.
4. Use mounting bracket holes to secure amplier
5. Install amplier with clearance from other objects
for improved ventilation.
