Installing Components
Mounting Speaker Horns
1. Select locations according to the requirements in "System
Mounting" on page 7. Place speakers so sound projects out,
toward students exiting the bus. For example:
• in the engine compartment - on the radiator frame, or just inside
the grille (mount as close as possible to openings)
•
in a cavity under the bus floor (e.g. behind the entrance door)
•
on the firewall, or frame-mounted (downward-facing)
2. Use the supplied drilling template (700-1145) to mark the 4 screw
holes on the mounting surface.
3. Drill the screw holes, then mount the bracket to the surface using
the 4 supplied #10 x 3/4" screws.
4. Place the speaker in the bracket so the holes line up, and insert the
2 bracket screws. Use the supplied washers, and thread the nuts
onto the screws.
5. If required, pivot the speaker horn toward an opening, then tighten
the speaker bracket assembly.
TIP: Avoid exterior mounting locations
To help prevent damage to speakers, we recommend against
mounting horns on exterior bus panels.

Center Cone
Drill Drainage Hole at
Cone's Lowest Point
NOTE: Water drainage
If the speaker is mounted low on the vehicle with the center
cone facing down, drill a hole to allow any accumulated
water to drain:
•
Drill a 1/8" hole at the lowest point in the center cone.
• The drainage hole is not required if the cone points
upward or sideways.
