TWEETER MOUNTING
1. Check for proper clearance: The flush mount
kit is 7/8" (22.2mm) deep.
2. Mark the center of the spot and cut a
2" (50.8mm) diameter hole using a hole
saw, drill bit or razor knife.
3. Assemble the cup, clamp and machine
screw loosely as shown.
4. Route wires through the round opening in the
bottom of the cup.
5. Press the assembly into the 2" (50.8mm) diameter
hole until the clamp edge is below the mounting
surface, then tighten the screw. The legs of
the clamp can be bent outward by inserting
ascrewdriver through the holes in the cup
while still mounted.
6. Connect wires from the tweeter terminals of the
Crossover to the tweeter itself using the faston
connectors. Connect the red wire from the (+)
terminal of the Crossover tweeter output to
the red (+) wire from the tweeter.
7. Mount the tweeter by snapping it into the
mounting cup.
