ULTRA CLASSIC, ELECTRA GLIDE, STREET GLIDE AND TRI GLIDE INSTALLATIONS
Please go to page 3 for Road Glide and Road Glide Ultra installation.
First Step - Remove the Fairing
A- Remove the top bolts on the bottom of the windshield. After the bolts are
removed, carefully remove the windshield.
B- Remove the screws on the bottom sides of the fairing. This will allow the
fairing to be removed.
C- Pull the fairing forward and up slightly, the harness connecting the headlight
will need to be removed to completely pull the fairing away from the bike.
a. Be careful to not bump the fairing against the signal lights or other
installed lights connected to the front fork. A sock or other fabric can
be used to protect the side lights during fairing removal.
Second Step - Remove Existing Speakers
A- Pull the speaker wire connectors from the speakers, take care to pull them
from the plastic connector and not the wires so that the stock wire harness
is not damaged.
B- Use a Torx driver to loosen the 4 screws holding on the stock speakers.
C- Keep track of which wires go to the clutch and brake side speakers.
D- The speaker grill assembly needs to be removed from the stock speaker,
make sure to keep it in a safe place or remember its orientation. This will be
important for mounting the new speakers in place.
Clutch Brake

Third Step - Mount the New Speakers
A- Take the new speaker and place the speaker ring on the front. This correctly
spaces this high performance speaker so that it performs to maximum
potential.
B- Orient the new speaker into position as seen in the below image to
ensure the terminals are in the easiest position to connect the speaker
wires.
C- Retighten the speaker screws until the speaker is held tightly against
the fairing.
Fourth Step - Route the Power Wire (2 People Recommended)
A- Run the wire harness along the factory harness.
B- Loosen the front two gas tank bolts using a T40 Torx driver.
C- Loosen the rear gas tank bolt using a T40 Torx driver.
D- Lift the gas tank up enough to pop open the plastic wire channel on the
Brake side. Take care to not pull out fuel lines.
E- Run the wire down though the wire channel and then snap the top of the wire
channel back in place.
F- The gas tank can be lowered back into place and the mounting bolts can be
put back and tightened in place.
G- Attach the power and negative wires to the battery.
Fifth Step - Connecting the Amp and Speakers (Ultra Classic Electra Glide, Street
Glide, Tri Glide)
A- Connect the MTX wire harness to the factory speaker wiring, making sure
the clutch side and brake side are connected to the correct input wires. The
wires are marked with a tag on each end. Plug the MTX harness connectors
into the corresponding factory connectors. Please ensure the connections
are secure so they do not come loose when riding.
B- Connect the speaker output wires to the new speakers mounted to the
bike. Also make sure to keep the clutch side and brake connectors
directed to the correct side. The speaker output wires are marked with a
tag indicating clutch or brake and have female fastons on each end that
will connect to the new speaker.

C- Unplug the stock wire connected to the center of the cigarette lighter. Then
plug in the blue wire from the MTX wire harness into the cigarette lighter, and
then plug the stock cigarette lighter wire connector into the extra connector
on the MTX wire harness.
D- If the MUD amp included with your kit has a High Level switch, move the
switch to Low Level. The MTX harness converts the signal to low level to
correctly work with the MUD amplifier.
E- Turn the gain to max and switch the filter to high pass.
F- Place Hook and loop fastener on bottom of the amplifier, and the top of the
radio.
a. If the radio does not have any modules on the top place the amplifier
with the wire harness pointing towards the brake side and make sure
the amp is pushed as far back on the radio as possible.
b. If the radio does have a module on the top place the Hook and loop fastener on the
open side of the radio. Place the amplier with the wire harness
pointing forward. The amp should be pushed back as far as possible
to keep it from interfering with the outer fairing.
G- Connect the amplier connectors to the MTX wire harness. There are 3
connections 1 large rectangular connector, and 2 bullet power connectors. Take
care to keep the power wire polarity correct. Red to Red, Black to Black.
a. Make sure the connections are securely snapped together.
H- Open fuse holder and place the 15 amp fuse in the holder.
I- Turn the bike to ACC and test to make sure the amplier and speakers power
up. If all works reverse the process to put the fairing back in place.
