Install as shown in the diagram here. Use the

supplied mounting clips unless the factory holes

already feature threaded inserts. Hand-tighten the

screws evenly to avoid bending the speaker frame!

INSTALLING YOUR TR400-CXi

COAXIALS IN CUSTOM 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.

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” (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,

hole saw or nibbler, 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 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 in the diagram at the

bottom of this page.

Hand-tighten the screws evenly to avoid

bending the speaker frame!

Break off small pieces of the supplied butyl

adhesive putty and place them on the inside of each

grille tray. This adhesive will hold the grille in place

firmly and prevent rattling. Then insert the metal

grille into the grille tray, squeezing gently around its

edge until it seats firmly into the tray.

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 car,

many cars are not symmetrical!

• Always wear protective eyewear.

INSTALLING YOUR TR400-CXi

COAXIALS IN FACTORY 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 TR400-CXi. You may also

choose to run new speaker wires...refer to the

custom installation section for details. 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.

Your new speakers have been designed to install,

without modifications, into most vehicles that accept

a 4-inch (100 mm) or 4 x 6-inch oval speaker

(adaptor plates are supplied for the latter). Most

factory 4-inch speakers use four mounting screws

which will line up with the mounting holes on your

TR400-CXi speakers. In some vehicles, only two

mounting holes are used and there is insufficient

clearance for the two extra mounting tabs. If this is

the case, bend the redundant tabs back and forth

until they break off (all four tabs on the TR400-CXi

are perforated for this purpose). After breaking off

the unwanted tabs, please handle the speaker

carefully, as the broken edges may be sharp.
