BEFORE STARTING

MTX recommends that you have your new speakers installed by an authorized MTX retailer, prefer­ably MECP certifi ed. If you do decide to do it yourself, make sure you have read the instructions
carefully and that you have the following tools:

• Electric drill

• Phillips bit or screwdriver

• 1/8” bit

• Door panel puller

• Wire cutters/crimpers

• Metal cutting tool

• Safety glasses

• 2mm hex wrench

• X-acto knife

Throughout installation, keep in mind the ultimate objective of creating an ideal soundstage and ex­ceptional imaging. This refers to the experience you get when you sit in your seat with your head up
and shoulders straight, close your eyes, and listen. Where does the music seem to be coming from?
In an ideal world, you would hear all music from front and center, meaning it sounds like a band is
performing on your hood. Raising the soundstage is a very important process and every option should
be considered in order to have your sound as up and in front as possible.

Removing the Door Panel

Please be aware that today’s cars have door panels that are not designed to come apart easily; they
are designed by the factory to sit tight against the door and not rattle. It is important to note that if the
proper procedures are not followed, the door panels can easily become damaged and make them fi t
improperly when you’re trying to reinstall them.

Use a door panel puller to remove the door panel, and be aware there are often hidden screws that,
if overlooked, can cause the panel to crack or break when force is applied to remove door panel. It
might be a good idea to do some research on your specifi c car to be sure they are all removed before
continuing. Even new car owner needs to be aware of this potential issue. Buying a new door panel
is an expensive process so please take note of the potential for damage.

With the door panel off, it is a perfect time to add sound dampener. The main goal of sound dampen­ers is to add mass to the metal in the door, causing less rattle and “ring” which will help to improve
the overall sound of your new speakers. It also helps prevent against outside noise by adding insula­tion. Sound dampening material can be purchased from your local retailer and is available in many
different forms, and kits, for many different applications. Please make sure you purchase the correct
type for your specifi c project.

Note: Before cutting anything, please use common sense and make sure that no wires or glass will
interfere with cutting tools. ALWAYS WEAR PROPER SAFETY GLASSES. Be sure all wires are clear of
moving parts such as window crank mechanisms and trunk hinges. Use rubber grommets when run­ning wires through sharp edged metal holes, which may wear through the wire’s insulation.

Do not mount speakers where they could come in contact with:

• The door’s window glass

• The window crank handle or gear assembly when rotated

• The trunk springs, shock towers, or trunk lid

• The gas tank or fuel lines

INTRODUCTION

Thank you for choosing MTX to help reach your ultimate goal with your vehicle. Adding MTX TXC
High-end Component speakers and a matching MTX amplifi er with StreetWires connections will put
you in a better position to hear, feel, and experience all of the music the artist intended.

TXC series component speakers are the best in the MTX offering of full-range speakers. They offer
many added features that are designed for the distinguished listener. Five levels of tweeter attenua­tion, three positions of Off-axis adjustments, and Bi-amp inputs are just some of the features that will
help reproduce the music with exceptional dynamics and detail regardless on mounting location and
position within the vehicle. The TXC series also offers an add-on midbass driver and/or tweeter that
further defi ne the musical experience. The TXC6.0 is an additional woofer that can change this 2-way
system into a true 3-way system, while the TXC.1 is an additional tweeter that adds a new dimension
to the imaging. Call 1-800-CALL-MTX for more information.

TWEETER MOUNTING

When positioning the tweeter for the best imaging, aim the passenger side tweeter toward where
the driver’s head will be. The same process should also be completed on the driver’s side tweeter but
this time you’ll aim the tweeter toward where the passenger’s head will be. Positioning the tweeters
in this manner will help to set up a very solid soundstage.

MIDRANGE MOUNTING

To get the best possible music reproduction, it is important to isolate the sound that is produced from
the rear of the speaker from the sound that is produced from the front of the speaker. To isolate the
front from the back wave, make sure the speaker is mounted in a baffl e or plate, so that the back of
the speaker is in a sealed chamber.

Surface Mounting

• Select mounting location. Mark wire hole and screw locations using the surface cup as a template.

• Drill holes for tweeter wires and mounting screws

• Using the supplied screws, attach the surface cup to surface

• Run tweeter wires through the hole and twist the tweeter into the cup

• Connect the tweeter wires to the supplied crossover

Flush and Angle Mounting

• Select mounting location and mark a 1-7/8” diameter hole with supplied template

• Cut out the 1-7/8” hole (a hole saw is recommended for metal and hard plastic surfaces;
an X-acto knife for any other surface)

• Place the supplied bevel headed screws through the fl ush/angle cup and thread into the
mounting clip, but do not tighten

• Take the assembled fl ush/angle cup and mounting clip and place them into the 1-7/8” diameter
hole, making sure the mounting clip goes completely through the hole

• Tighten the screw in the base of the fl ush cup until the cup is completely tight

• Split tweeter wires and run through the holes and twist the tweeter into the cup

Mounting

• Select the mounting location (door panels, rear side panels, rear deck, etc...)

• Using the supplied templates, mark the mounting holes on the door panel or rear deck

• Drill or cut the required holes as needed

• Install the units as illustrated in the diagrams

*Note: The TXC6.1 and TXC6.0 are supplied with plastic mounting adapters. The adapters are used
to convert the smaller basket sizes needed for European models to the larger domestic sizes. The
plates will allow a tight and accurate fi t, decreasing the need to fabricate adapters out of MDF or
plastic.

For answers to further questions, please call 1-800-call-MTX

Three Way System

While the TXC sound quality is the best in the market, the addition of the TXC6.0 woofer can create an
even better musical experience with more precise reproduction. The TXC6.0 has a separate cross­over, and the 2-way system can become a true 3-way system where it splits the lower frequencies
between the original midrange and this additional woofer. This makes each speaker responsible for
fewer frequencies and allows clearer, more accurate reproduction.

CROSSOVER MOUNTING

When choosing the mounting location of the crossover, accessibility is important. Adjustments to
the on-/off-axis setting and tweeter attenuation are to be made after the components have been
installed, so convenient positioning of the crossover is crucial. Also, the crossover has electronic
components that must be mounted so it does not come in contact with moisture.

WIRING

When installing these separates consider the age of the factory wiring and gauge (size) of wire. If
the vehicle is an older model or was pre-wired with small wire (18 gauge or less), running new high
performance wire (http://www.streetwires.com/products/speakerCable/microUltraCable.cfm) will be
necessary. The speaker wire should run from the amplifi er’s output terminals, under the carpet and
through the factory rubber boot (loom) that protects the wires in the inner door jam. If the factory
boot cannot be used, take other measures to protect these wires as best you can. Sometimes the
door has to be completely removed to use the factory boot. If this is something that you do not feel
comfortable doing, please ask a professional to help you. The wires should originate from the ampli­fi er and attach to the crossover inputs.

CROSSOVER CONNECTIONS

Included with each TXC component system is a 2-way 18dB (tweeter)/12dB (midrange) octave
separate crossover network. The crossover networks allow each driver within the component system
to independently recreate frequencies within a precisely-designed range so that the speakers do
not become distorted by trying to reproduce frequencies that they are not physically able to. This
network ensures that the tweeter does not receive low bass notes and the mid-bass driver does
not receive high frequencies. The 18dB (tweeter)/12dB (mid) octave design complements both the
tweeter and mid and provides greater musical detail.

Note: Pay close attention to the markings on the crossover to be certain the correct speakers are in
the correct outlet. If a tweeter is accidentally asked to play the frequencies reserved for a mid-bass
driver, it will be damaged.

BI-AMP CONFIGURATION

These crossovers feature Bi-amp connections so that the components can be wired to drive the
tweeter and midrange independently using two amplifi ers. When using the components in the Bi­Amp confi guration you are going to need two stereo amps or one four channel amp to run a pair of
components. You will need to remove the Bi-amp jumpers from the input connection points of the
crossover. Connect the desired amp or channels to the tweeter input. The second amplifi er, or third
and fourth channels of the 4-channel amplifi er, will be connected to the woofer input on the cross­over. When the crossover is set up in this confi guration, the fi nal load will be 4 ohms.

Note: It is important to make sure the gain of each amplifi er is matched. Final gain level adjustments
should be made using the crossover settings.

TWEETER ATTENUATION ADJUSTMENT

When setting the attenuation of your tweeter, you are going to want to adjust this level by the dis­tance from tweeter to listener as well as personal preferences. The attenuation has fi ve levels that
range from 0dB to –6dB. Generally, this would be set up with 0dB being further away, and –6dB being
closer, to the listener’s ear. If you have the attenuation set at 0dB and the speakers seem too bright,
adjust the jumper downward until it matches your personal taste. If the speakers seem too dim or
quiet, adjust the tweeter upward.

Note: The tweeter adjustments will also dramatically affect the balance between your tweeter and
the 0, 30, and 60 degree setting of your midrange. After setting the tweeter to a comfortable level,
you may need to readjust your midrange off-axis adjustment to achieve the optimum balance.

THREE LEVEL OFF-AXIS ADJUSTMENT

MTX designed the TXC components to compensate for undesirable factory mounting locations within
the vehicles by including a three level on-/off-axis adjustment feature. Since you cannot move the
factory speaker mounting locations within the vehicle, these adjustments will help to deliver sound
that is clear, deep, and positioned like it is coming from directly in front of you. The music will have
a sense of depth where it sounds like it is not confi ned by the windshield but rather coming from the
road in front of you.

There are three settings on the crossover for Off-axis adjustments- 0˚, 30˚, and 60˚. These positions
will compensate for the speaker placement and will use your vehicle’s unique environment to create
the best sounding system possible.

Note: For applications greater than 60˚, the 60˚ position setting is recommended

Once the speakers are installed in their fi nal locations, do the “sit in the seat and close your eyes
test.” The vocals should be jump out at you, be cleanly defi ned, and move from side to side while the
instrumentation should be full and distinct layers. If you don’t hear your music in this fashion, select
a different jumper position and repeat the “sit in the seat and close your eyes test” (The jumper
settings listed below are our recommended starting points). Take time to listen to the components in
each of the jumper settings in detail to determine which sound is best for your application.
