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 1-7/16-inch (37 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 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).
