Tweeter Installation
When flush or surface mounting tweeters, make sure the desired location can accommodate the hole sizes
and depth required. The tweeter can also be surface mounted atop the dash, door, or rear deck. Mount cup
using the provided hardware, flush mount illustration shown below. The flush mount bezel requires cutting a
1.75" (45mm) round opening. Be sure there is AT LEAST 1 INCH (25.4mm) behind the panel so the tweeter
has adequate clearance. Remember when using a hole saw the thickness of the saw teeth will add to the cut
diameter. Mount the surface cup at the desired angle with provided screws in the tweeter mounting kit. Route
speaker wires through tweeter cup, connect the tweeter to wires, and snap the tweeter into the cup by
aligning the notches in the tweeter cup with the notches in the tweeter base.. Be careful not to push on the
center of the tweeter grill.

Crossover Installation
Install in a well ventilated area whenever possible. If you must install the passive crossovers in the doors due
to the use of factory wiring. As you "feed" into the door cavity, ensure that the crossover is installed behind
the door panel instead of inside the door itself. This will offer the greatest capacity for avoiding any water
damage caused by rain or moisture. Also avoid placing it near factory wiring looms to ensure no radiated noise
problems. Connect the input side labeled "AMP" of each passive crossover to the amplifier's speaker output
terminals. Be sure to observe correct polarity for positive and negative terminals. Next, connect the middle
terminals labeled "MID" to the midrange speaker. Be sure that the wiring is protected all the way to the
terminal and that the wires are secure at both the speaker and passive crossover. Finally, connect the end
terminals on the far right hand side labeled "TWT" to the tweeter. Be careful to observe the correct polarity
when connecting the tweeter to its lead wires as these are smaller gauge and require care and patience to
connect correctly.
