SURFACE-MOUNT INSTALLATION
1)  Remove the vehicle panel and check to ensure that 

the mounting screws will have adequate clearance.

2)  Place the surface-mount fixture on the 

vehicle panel at the desired mounting location 
with the mounting screw holes positioned 
vertically, at twelve and six o’clock. 

3)  Mark the location of the two mounting screw 

holes and the approximate center of the 
right rectangular cutout (for the wires).

4)  Using a 1/16-inch (1.5 mm) drill bit, drill a pilot 

hole through the panel at the two screw locations.

5)  Using a 1/4-inch (6 mm) drill bit, drill 

the hole for the tweeter’s wires at the 
location you marked in step 3.

6)  Screw the surface-mount fixture to the  

vehicle panel using the supplied #6 
sheet metal screws (hand-tighten). 

 
7)  Feed the tweeter wires through the rectangular 

hole in the mounting fixture and the 1/4-inch hole 
you drilled in the panel. Then, snap the tweeter 
into the surface-mount fixture.

8)  Connect the tweeter’s wires to the wire leads from 

the crossover,  observing correct polarity. 

9)  Re-install the vehicle panel, taking care to 

route the new wiring so as not to interfere 
with any vehicle mechanisms (window 
mechanisms, for example).
