TWEETER INSTALLATION

First, run speaker wires from the tweeter output of the crossover (see Wiring Diagram B on page 5) to the desired tweeter mounting locations, observing the same precautions as mentioned in the woofer installation section. Terminate the wires with the supplied 2.8 mm male crimpable connectors.

TWEETER FiXTURE INSTALLATION: The dome tweeters supplied with your 

C3-650 system have been designed for maximum mounting versatility in a component configuration. There are two primary methods by which the tweeters can be mounted in your vehicle:

Flush-Mount Installation

The dome tweeters supplied with your 

C3-650 system have been designed to integrate with your installation in a clean, unobtrusive manner using a flush-mount cup. This compact mounting fixture is installed using the method illustrated in Diagram K and requires a mounting hole with a diameter of 1.875 in. (47.6 mm).

At least 1.70-inch (43.2 mm) of clearance is required behind the mounting surface of the tweeter for the spring clips and 1-inch machine screws used in mounting the fixture. In limited depth applications, it may be necessary to cut down the length of the machine screw, or to use a shorter screw (not supplied). Hand-tighten the machine screw until the fixture is secure (See Diagram K).

Surface-Mount Installation

In this application, you will not need to cut large holes in your vehicle’s panels for the tweeters. You will only need to drill a hole for the wires and two smaller holes for the mounting screws. This application is useful when mounting the tweeters to a panel that has insufficient clearance behind it for the tweeter’s magnet structure.

Using the fixture as a template, mark the screw hole locations and a location in the center of the fixture for the wire hole. Remove the fixture and drill pilot holes for the screws and a 1/4-inch (6.4

mm)for the wires. Use the supplied #6 x 1.00-inch sheet metal screws to secure the fixture as shown in Diagram L. Next, route the tweeter’s positive (+) and negative (-) wire leads through the 1/4-inch center hole. The tweeter is secured to the fixture using a simple bayonet (twist and lock) mechanism. To attach the tweeter to the surface-mount fixture, observe the indented locking slots on the outer edge of the tweeter body and align these with the tabs visible on the inside walls of the fixture. The tweeter should slide into place easily and can then be locked by pushing down on the tweeter and giving it a small clockwise turn (See Diagram L).
