FLUSH-MOUNT INSTALLATION

1)  Detach the preinstalled surface-mount fixture 

by inserting a small flat screwdriver into the 
slots behind the tweeter flange and carefully 
pry open to release.

2)  Remove the vehicle panel and check the 

desired mounting location to ensure that 
there is adequate

 

clearance behind the 

panel for the tweeter’s magnet structure and 
mounting hardware.

3)  Carefully cut a 1-3/4-inch (44 mm) diameter 

hole in the vehicle panel. This will achieve a 
snug fit and allow the tweeter flange to conceal 
the cut line.

4)  Select a suitable length stud bolt for your 

panel’s thickness and screw its short end into 

the rear of the tweeter using the fixed M4 nut 
to tighten.

5)  Insert the tweeter from the front of the panel 

(do not attach the spring clip at this time).

6)  Attach the spring clip from behind the 

panel using the supplied

 

M5 nut and 

tighten by hand until the tweeter is tight 
on the panel. Do not overtighten.

8)  Connect the tweeter’s wires to the supplied 

harness with the in-line high-pass filter, 
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).

Stud bolts are provided in two lengths to accommodate different panel thicknesses.

10 mm length

25 mm length
