 REAR 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 

harness (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 installa-

tion. 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 “rears”. At one end of that harness is 

a black plug with 4 wires and a blue plug with 4 wires. Plug the black 

one 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” ad-

hesive, 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  

temperature 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.
