GETTING STARTED
Please read the entire manual before starting. It
WILL
help and will familiarize you with all
the options of the amp.
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 scratch-
es or “dings” from dropped tools or fasteners etc.
Note: If this amplifier is being mounted in a FLTR “Road Glide”, Hogtunes Part
RG 40.4 Adaptor Kit is required. (Drag Specialties Part #4405-0232)
Step #3: Take the 2 wires off each front speaker by gently pulling one at a time. Let the
factory speaker wires hang for now. If installing on an Ultra, remove each rear
speaker and let the rear speaker wires hang for now.
Step #4: On the side of the amplifier is a 2ch/4ch switch that needs to be set for your
system. In the “2ch” position, all 4 channels are driven equally with no option
of a fader on the radio controlling the front/rear. This is ideal for “Non-Ultras”
where your installing fairing speakers, (and tweeter pod if present), and either
rear speakers on a tour-pak, or speakers in fairing lower glove boxes. If install-
ing fairing speakers, and lower speakers on an Ultra, the amp will go in “2ch”
mode and the 4 front speakers are controlled by the front portion of the fader.
The rear speakers get powered by the radio, and are controlled by the rear
portion of the Ultras fader. When the amp is in 2ch mode, the 3 position “gain”
switch on the amp becomes active. Whatever speakers are plugged into the
rear output of the amp can now be controlled by this gain switch. This acts as
a “set it and forget it” quasi fader and allows for better control of your system.
Tip: The front channels always have full power going to whatever speakers they
are powering. If your powering fairing speakers and speakers in fairing lower
glove boxes, and find your front speakers are too loud, you can plug the front
speakers into the rear channels on the amp, and lower speakers into the front
channels of the amp. The gain switch will now allow you to adjust the power
going to the front speakers. This gives you awesome adjustment of your system!
Please finish your install as per this manual before adjusting.
If installing in an Ultra Classic where the amp will power front speakers (and
tweeter pod if present), and rear speakers, the amp will go into “4ch” mode.
This allows the radios fader to control front/rear adjustment.
Step #5: The power harness has an 8 pin white plug with 3 red wires, 3 black wires,
and 1 orange wire. Locate this and plug it into the white socket on the amplifier
marked “power”. The input harness has a smaller black 8 pin plug with smaller
gauge wire. Plug this into the black socket on the amplifier marked “hi level
input”. Locate the 4 pin black plug with black/brown, and black/blue wires.
This will plug into the “front out” on the amp, which is a 4 pin black socket.

A) If installing on an Ultra where the amp will power fronts and rears: Locate the
long “rear speaker” harness with 8 black wires in it. One end has an 8 pin white
plug, the other end has two 4 pin connectors. One of the 4 pin connectors on this
long harness will plug into the empty 4 pin plug on the input harness. It will only
go on one way. The other 4 pin plug on the rear harness will plug into the “rear
out” which is a white socket on the other side of the amp. Remember to have the
“2ch/4ch” switch set to “4ch”.
B) If installing on a EG Classic, Street Glide or Road Glide where the amp will power
fronts and rears: Locate the long “rear speaker” harness with 8 black wires in it.
One end has a white 8 pin connector, the other end has two 4 pin connectors. One
4 pin plug on the rear harness will plug into the “rear out” which is a white socket
on the output side of the amp. The other white connector on the same end of this
harness is not used. Remember to have the “2ch/4ch” switch on “2ch”
C)
If installing where the amp will power fairing speakers, and fairing
lower glove box speakers:
Locate the wire harness with a white 4 pin white
plug on one end and a 4 pin black plug covered in heat shrink. Plug the white plug
on this harness into the rear output on the side of the amp. Remember to have the
“2ch/4ch” switch on “2ch”.
If adding rears to this configuration,
locate
the long “rear speaker” harness with 8 black wires in it. One end has a white 8
pin connector, the other end has two 4 pin connectors. One 4 pin plug on the rear
harness will plug into the “bypass out” which is the blue socket on the output side of
the amp. The other white connector on the same end of this harness is not used. Re-
member to have the “2ch/4ch” switch on “2ch”.
IMPORTANT:
The radios power
is diverted to this set of speakers, so the speakers ohms (
Ω
) used in this location
MUST
match the ohms the radio works with. For 2006-Current factory radios, 2
ohm speakers are required. For 1998-2005 factory radio’s, 4-8 ohm speakers are
required.
The amplifier is designed to mount on top of the radio inside the fairing so when installed,
the large factory wire harness that goes across the back of the speedometer and tachom-
eter will sit in the trough or “dish” cut into the top of the amplifier, as show in Diagram 1.1
below.
