If you still need assistance, please consider a professional
installation by your motorcycle dealer.
Thank you for choosing the Hogtunes REV 225-AA Amplifier for 1998-2013
Bikes. Since positive word of mouth is the best way to grow our business, we
want your new system to work as well as it was designed to. If you have any
questions or concerns, we are here to help.
To help protect your bike’s electrical system and battery, the amp has a built
in feature where it will turn itself off if it sees less than 10.5 volts, whether
the bike is running or not. If you’re listening to your stereo while not riding,
this feature can help protect your battery so the bike can still start. If you’re
riding and the amp shuts off, this could be showing a potential issue with your
charging system. If this feature is activated and the amp shuts off, it will turn
the amp back on again if the voltage exceeds the 10.5 volt threshold.
REV 225-AA is rated for 112.5 watts per channel @ 2 ohms. Although this
amplifier makes its highest power with 2 ohm speakers, if Hogtunes 5.75
ohm speakers or 4 ohm car speakers are used there will still be a noticeable
improvement in volume and sound quality.
The REV 225-AA amplifier is a Class D design. It should be
understood that ALL Class D amplifiers, REGARDLESS OF BRAND, cause
a reduction in FM reception. The REV 225-AA features a proprietary
circuit design called R.E.M.I.T. (Reduced Electro Magnetic Interference
Technology) that Hogtunes believes gives the BEST FM reception
available for any Class D Amplifier designed for a motorcycle.
If you add a 2nd or 3rd model amplifier to your system, reduction
of FM reception is increased and is considered normal.
Hogtunes understands that some riders prefer the cosmetics of
in fairing antennas, however it should be noted that NOTHING
works as well as the factory antenna. If FM is an important part of
your riding experience, we strongly advise against the use of
any in fairing type antenna!

MOUNTING CONSIDERATIONS/
REQUIRED ADAPTOR KITS
Depending on the model of bike or what is already installed in the bike, a
Hogtunes amplifier adaptor kit may be required.
If you have a Standard, EG Classic, Street Glide or Ultra and this is the only
Hogtunes amp in the system, the amp will adhere to the top of the radio using the
supplied “hook and loop” adhesive. No adaptor needed.
If you have a Standard, EG Classic, Street Glide, or Ultra and this will be the
2nd amp in the system, Hogtunes “2CHSP” (Drag Specialties Part # 4405-0234)
is required. This kit bolts into your fairing and locates the REV 225-AA between the
radio and brake side speaker. Please do not continue the install until you have the
required parts. 2CHSP can also be used if you prefer not having an amplifier sit
on top of the radio.
If you have a Road Glide or Road Glide Ultra, Hogtunes has two different RG
adaptor kits available. If you don’t have the required adaptor kit, please do not
continue the install until you have the required parts.
1) If this is the only amp in the system or if you already have a Hogtunes NCA
450-AA or NCA 40.4 and are adding to the system, you will need Hogtunes
RG2CH-AA ( Drag Specialties Part # 4405-0486) which bolts the amp to the
main studs that attach the inner fairing to the frame of your bike.
2) If there is a REV 225-AA in the bike, it should be mounted to a plate
attached to the main studs that hold the inner fairing to the frame of the bike.
The second amp will bolt in using Hogtunes RG4CH-AA (Drag Specialties Part
# 4405-0405). This will locate the second amp off to the extreme brake side
of the inner fairing.
If you do not have the required adaptor, please consult your retail dealer.

GETTING STARTED
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 main power harness and plug it into the matching connector
on the amplifier. Locate the 8 pin harness and plug it into “Audio Input”
on the side of the amp. If using this amplifier to power front speakers
(and tweeter pod if present) locate the 4 pin harness ending in a black
plug and plug it into the black 4 pin connector on the amp. Make sure
to plug this into the black plug and NOT the blue plug on the 8 pin input
connector. NOTE: If using this amplifier to power Hogtunes 692.2/
Lids 6x9”speaker lid kit, FL-7W 7” Fairing lower woofer kit or speakers
as part of Hogtunes rear speaker pod kit, the speaker wire harness that
comes in those kits will now plug into the 4 pin black plug on the side of
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” adhesive and must
sit so if in front of the bike looking down, the
power connector is on your left and the
amplified output 4 pin black “pigtail” is on
your right. The amplifier needs to mount as
far back on the radio as possible so the
fairing can go back on. On 1998-2005
model bikes, it is a tight fit--but will go.
2006-2013 (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 one
piece on either side of this bump. The amp
will then mount flush as shown in Fig 1.1.
Most adhesives work best at room
temperature or higher.
NOTE: 2006- 2013 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 plate 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 plate’s
instructions. NOTE: Use the harnesses that comes in this kit and NOT
the harnesses that came as part of the selected Hogtunes adaptor kit
for RG.
Wiring the aMplifier
Step #1a: Follow this step 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.
Unplug the factory speaker wires on the clutch side of the bike and plug
the yellow/black wires into 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. Unplug the factory speaker wires on the brake side of
the bike and plug the green/black wires in to those. NOTE: The blue
4 pin plug with black wires on the input harness is an “expansion port”
which is used to send music to a second amp or is used to send radio
power to run other speakers on the bike. You can see how the
expansion port can be used further on in this manual.
Step #1b: Follow this step if this is the second amp in the bike and the first amp
is a Hogtunes NCA 450-AA or 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 450-AA or 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 REV 225-AA. Take the
red/black wires on the bypass plug and plug them into the green/black
wires on the input harness of the REV 225-AA.
Step #1c: Follow this step if this is the second amp in the bike and the first amp is
also a Hogtunes REV 225-AA, REV 200-AA or 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
“First” REV 200-AA. Take the white/black wires on the bypass plug
and plug them into the yellow/black wires on the input harness of the
REV 225-AA being installed. Take the red/black wires on the bypass
plug and plug them into the green/black wires on the input harness of
the REV 225-AA being installing.

Step #2: Earlier in the install, you located the black 4 pin plug with the
blue/black and brown/black wires on it and plugged it into the
“amplified output” on the amp. The blue/black wires will plug directly
to the speaker on the brake side of the bike. The brown/black wires will
plug directly to the speaker on the clutch side of the bike. Please double
check that this harness is plugged into the BLACK pigtail plug on the
amp and not the blue 4 pin plug on the input harness
Step #3: Routing the power harness - For Standards, Street Glide,
EG Classic, and Ultra Classic - For 98-06 bikes, the power harness
will pass under the inner fairing where the throttle and idle cables pass
through on the brake side of the bike. The harness is designed to be
routed between the frame backbone and gas tank on the brake side of
the bike and come out just behind the gas tank. You MAY need to undo
the back bolt of the gas tank and pivot the tank up to allow the harness
to pass through at the back of the gas tank. Be sure to re-install this bolt
and torque to factory specs! For 2007-2013 bikes, the balance of the
main wire harness will pass under the inner fairing where the main wire
harness passes through on the brake side of the bike. Loosen the tank
console and run wires up and over the gas tank, but under the tank
console. There is a provision on the front of the tank console for wires to
pass. Secure the amplifiers harness to the bike’s factory harness using
zip ties. When correctly installed, the power and ground wires are the
right length to connect onto the battery.
NOTE: although not necessary, the power harness can run along the
back bone of the frame if you choose to remove and reinstall the bikes
fuel tank. Attach the red wire to the positive (+) battery terminal and the
black wire to the negative (-) battery terminal. The factory battery wires
are also re-installed at this point. Turn the ignition of the bike to the “on”
position and play the stereo at low volume to verify the system is
working fine.
Step #4: Now is a good time to “clean up” and secure any wiring inside your
fairing using supplied zip ties. For best possible FM reception, DO NOT
attach any of the amplifiers wiring to any factory antenna wires. Doing
so will hurt your radios ability to receive FM signals!
IMPORTANT: With all wires secured, turn the front
wheel to each extreme side, making sure that any
wires cannot bind or impede the steering of the
motorcycle. Failure to do so can cause an accident
resulting in serious injury or death!
Please see you can easily add on to your system if you want over the
next 3 pages. We strongly suggest you read the “Adjusting Your System”
section on page 10.

systeM upgrade #1
This system is an easy way to add rear speakers to the bike if it has a King
Tour-Pak®. Hogtunes rear speaker pods come with a wire harness set up for quick
detach Tour Paks that will plug right into the expansion port on the amp.
IMPORTANT: Since the RADIO power will be used to power the rear speakers,
you must use rear speakers specific to your year of bike!
Use expansion port to send
radio’s built in power to a
second set of speakers
(rears on Non-Ultra Models)
Optional HF-1
Tweeter Pod

systeM upgrade #2
This system has the incredible power of 2 REV 225-AA Amplifiers to your bike!
The first amp will run the 5.25” fairing speakers and HF-1 Tweeter Pod (if present).
The second amplifier is used to power a set of 692.2/Lids, FL-7W Fairing lower
woofers or rear Tour Pak speakers.
For all Standard/Classic/Ultra/Street Glide models, the purchase of Hogtunes
2CHSP adaptor kit is required! The metal plate in that kit is used to bolt the
second amplifier into the fairing
Optional HF-1
Tweeter Pod
Use supplied blue
plug to send signal
from expansion port
of rst amp to input of

systeM upgrade #3
This system adds a Hogtunes 4-channel amp; 2 of its channels would power the
front speakers (and tweeter pod if present) and the other 2 channels would power
rear speakers or fairing lower woofers. The original 2-channel amp would power
692.2/lids or lower speakers. You can literally build the system the way you want
based on the body work you have on your bike. This can be done at any time, all
bolt in, all plug and play! Hogtunes 2CHSP mounting plate is required to bolt the
REV 225-AA into the fairing.

adjusting your systeM-please read!
In order to make this new system perform as well as it was designed, please
take a minute to understand and follow these tips:
1) Set this “Automatic Volume Control” (AVC) to 3 bars. After extensive
on-road testing, we found that this AVC position works and sounds best.
This new amplier has been specically set-up for this radio setting.
2) This Hogtunes system is designed specically for a motorcycle at speed.
Exhaust noise and wind noise have been taken into careful consideration
in how your system performs. How this new system sounds in a driveway
or garage is radically different from how it will sound at highway speeds.
Although your system was set-up with a factory radio, with its bass and
treble controls in the middle position, if you feel the need to make
adjustments please do so (carefully) at your normal cruising speed.
3) If there is an aftermarket car radio on your bike, its functions will work
ne. Please remember that car radios are designed to work in an
environment with little or no exhaust or wind noise. Many car radios
have features such as equalizers, loudness contours, surround effects, etc.
These are all designed for a quiet environment and all of which will hurt
the ability to hear your motorcycle system at speed if left on. Please take
a minute and turn as much of these features off. With a car radio in
your bike, the only adjustments you should be able to access for best
performance are volume, bass, treble, balance and fader.
4) If using an external device to supply music through the radios AUX port,
we have an article on our website that can help make your
peripheral audio device sound as good as possible. The article is at:
