LOWER SPEAKERS
Step #1: Remove the seat, and both wires (+ and -) from the battery.
Step #2: Remove the outer fairing/headlamp assembly. Refer to a service manual
if you need help with this. Note: A towel on the front fender can help
prevent scratches or “dings” from dropped tools or fasteners etc.
Expletives will also be kept to a minimum.
Step #3: Locate the bag with 3 separate harnesses. It has the amps power har-
ness (red, black, and orange wires with a 3 pin green plug), input
harness (ending in an 8 pin white plug), and a front out harness (4 pin
black plug with blue/black, and brown/black wires). Put the 4 pin black
plug from this bag aside. It will not be used in this installation. Plug the
power harness into the amp, and make sure to secure the screws to
prevent the harness from backing out while riding. Plug the input harness
into the amp where it says “Audio Input/Exp. Port”. There is another
harness bag marked “lowers”. At one end of that harness is a black plug
with 4 wires. Plug that into “Amplified Output” on the amp.
Step #4a: Mounting the amp For Standards, Street Glide, EG Classic, and Ultra
Classic If this is the only amp in the system, the amplifier gets mounted
to the top of the factory radio using the supplied “hook and loop” adhe-
sive, and must sit so you can read the text on top of the amplifier as in
diagram 1.1 .The amplifier needs to
mount as far back on the radio as pos-
sible so the fairing can go back on. The
minimum distance from the back of the
radio to the most forward edge of the
amplifier is 5/8” (15mm). On pre-2006
model bikes, it is a tight fit--but will go.
2006+ (Advanced Audio) radios have
a “bump” on top of the radio that runs
from front to back down the center of the
radio. Cut the adhesive in half and apply
each piece on either side of this bump.
The amp will then mount flush. Most
adhesives work best at room tempera-
ture or higher. Note: 2006 and newer
Ultras have the CB module on top of the
radio. The amp will adhere on top of the
CB module so it is “half on/half off this
module as shown in Diagram 1.2. The
supplied adhesive is plenty strong for
this! The amp can adhere on top of CB
and XM modules without issue.

If this is the 2nd amp in the system, mount the amp to the
Hogtunes 2CHSP and install in your bike.
Step #4b: Mounting the amp For Road Glide or Road Glide Ultra – The amp will
mount to the plate and the plate will mount to the bike as per the plates
instructions. NOTE: Use the harnesses that come in this kit and NOT
the harnesses that come as part of your RG adaptor kit.
WIRING THE AMPLIFIER
Step #1a: If this is the only amp in the bike. On the audio input harness, locate
the yellow/black pair of wires with the male connectors. Un plug the
factory speaker wires on the clutch side of the bike and plug the yel-
low/black wires in to those. They will only go in one way. Also on the
audio input harness, locate the green/black pair of wires with the male
connectors. Un plug the factory speaker wires on the brake side of the
bike and plug the green/black wires in to those. Locate the Blue plug
with red/black, and white/black wires on it, and plug this into the “ex-
pansion port” which is the empty (also blue) plug on the input harness.
Take the white/black wires on the expansion port plug, and plug them
directly to the clutch side front speaker. Take the red/black wires on
the expansion port plug, and plug them directly to the brake side front
speaker.
Step #1b: If this is the 2nd amp in the bike and the “1st” amp is a Hogtunes NCA
40.4. Locate the Blue plug with red/black, and white/black wires on
it, and plug this into the “bypass out” (also a blue plug) on the side of
the NCA 40.4. Take the white/black wires on the bypass plug, and
plug them into the yellow/black wires on the input harness of the NCA
70.2. Take the red/black wires on the bypass plug, and plug them into
the green/black wires on the input harness of the NCA 70.2.
Step #1c: If this is the 2nd amp in the bike and the “1st” amp is also a Hogtunes
NCA 70.2. Locate the Blue plug with red/black, and white/black wires
on it, and plug this into the expansion port (also a blue plug) located
on the input harness of the “1st” NCA 70.2. Take the white/black wires
on the bypass plug, and plug them into the yellow/black wires on the
input harness of the NCA 70.2 your now installing. Take the red/black
wires on the bypass plug, and plug them into the green/black wires on
the input harness of the NCA 70.2 your now installing.
