GETTING STARTED

• 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.

SPEAKER PLACEMENT CONSIDERATIONS

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.

SPEAKER INSTALLATION

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

Factory Location: Run speaker wire to the desired mounting locations. 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. Wires should then be covered with a protective, flexible PVC sleeve and then run 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.

Your new speakers have been designed to install, without modifications, into most vehicles that accept a 5x7-inch(125 x 180 mm) speaker. Most factory5x7-inchspeakers use four mounting screws which will line up with the mounting holes on your speakers.

A spacer gasket has been included to fine-tunespeaker fitment. This gasket can be mounted on the front of the mounting flange, the back of the mounting flange or simply not be used in the installation.

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 air does not leak around the mounting flange. Air leaks will cause a severe degradation in sound quality. Seal any air leaks with an automotive-gradesealant material.

Connect the speaker wires to both sets of terminals on each speaker, observing correct polarity and making sure that the tweeter and woofer wires correspond to the correct terminals on both the speaker and the crossover.

Secure the speaker and spacer gasket (if applicable) to the panel by evenly tightening by hand mounting screws. Use the supplied mounting clips and the the provided #8 x 1.25 inch (32 mm) mounting screws unless the factory holes already feature threaded inserts.

Custom Location: Run speaker wire to the desired mounting locations. 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. Wires should then be covered with a protective, flexible PVC sleeve and then run 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.

!! WARNING

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

Select an even surface. Tightening a speaker onto an uneven surface can damage it. 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 on your interior panels, 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, make the circular cut out for the speaker. File any rough edges. Insert the mounting clips with the flat side towards the speaker as shown in Diagrams B/C (Page 5).

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 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.

A spacer gasket has been included to fine-tunespeaker fitment. This gasket can be mounted on the front of the mounting flange, the back of the mounting flange or simply not be used in the installation.
