• Turn off the audio system. It is also advisable to disconnect the negative (–)terminal of your vehicle’s battery whenever performing installation work.

• Before cutting, drilling or inserting any screw, check clearances on both sides of the planned mounting surface. Also check for any potential obstacles, such as window tracks and motors, wiring harnesses, etc. Check both sides of the

vehicle, many vehicles are not symmetrical!

• Always wear protective eyewear.


In most cases, your speakers will be placed into factory speaker locations. If you have some speaker mounting flexibility, keep the following in mind:

Lower mounting locations, such as the lower front corner of a door or a kick-panelprovide the greatest path length distances for the sound emitted by the speakers. For this reason, they are generally more desirable than higher mounting locations. Higher mounting locations will usually result in extremenear-sidesoundstage bias which compromises the stereo listening experience.



The speaker should be installed in one of the following ways depending on location:

Bottom-Mount Locations: If you will be using the factory speaker wires, it may be necessary to change the terminations. This may be accomplished by using an adaptor plug or simply by cutting the factory connector off and using the supplied crimp connectors to terminate the speaker wires. The large connector is for the positive terminal and the small connector is for the negative terminal of each speaker. You may also choose to run new speaker wires. Whichever method you choose, observe correct polarity in your connections. If you are unsure about any of these issues, contact your

JL Audio dealer for installation assistance.


Double check the clearance for both speakers before proceeding. Many cars are different from one side to the other!

Your new speakers have been designed to install, without modifications, into most vehicles that accept a 6 x 9 inch speaker. Most factory 6 x 9 inch speakers use four mounting screws or bolts which will line up with the mounting holes on your C2-690txspeakers. The speaker should fit so that no air leaks around the mounting flange. Air leaks will cause a severe degradation in sound quality.

Seal any air leaks with silicone, rope caulk or similar sealant material. Install as shown in the diagram here, using the supplied bottom-mountspacer rings and the supplied screws and mounting clips.Hand-tightenthe screws evenly to avoid bending the speaker frame!

Top-Mount Locations: Run speaker wire to the desired mounting location. If you are running wires into a door, use existing factory wiring boots

whenever possible. If you are drilling new holes, file their edges and install rubber grommets into each hole. Then, cover the wires with a protective PVC sleeve and run them through the door jamb. Make sure that the wires will clear door hinges and other structures in the door. If you are unsure about any part of this process, please contact your JL AUDIO dealer for installation help.


Double check the clearance for both speakers before proceeding. Many cars are different from one side to the other!

If you are cutting mounting holes into a custom location, use the supplied template to mark the desired mounting location. Mark the center and the outline of the mounting hole as well as the mounting screw positions. Before drilling or cutting, use a utility knife to cut any fabric, vinyl or leather from hole locations. These materials can easily be snagged by a drill or a saw, causing damage to the panel and possible bodily injury.

Drill four 1/8-inch(3 mm) holes for the speaker’s mounting screws at the positions you have marked. Also drill a pilot hole in the center of the speaker mounting hole at this time. Then, using a saber saw, or nibbler make the ovalcut-outfor the speaker. File any rough edges.

Insert the mounting clips with the flat side towards the speaker as shown in the diagram.

It is absolutely vital that the speaker frame fits into the mounting hole cleanly. This must be checked prior to tightening the screws. Do not force the frame into a hole that is too small! Do not tighten the speaker onto an uneven surface! This will damage your speakers. The speaker should also fit so that no air leaks around the mounting flange. Air leaks will cause a severe

degradation in sound quality. Seal any air leaks with silicone, rope caulk or similar sealant material.

Connect the speaker wires, observing correct polarity, and install the speaker and grille tray as shown.
