NOTE
DO NOT mix Stage I and Stage II speakers on the same vehicle.
NOTICE
Radio EQ MUST be updated by a Harley-Davidson dealer BEFORE operating the audio system. Operating the audio system prior to radio EQ update will IMMEDIATELY damage the speakers. (00645d)
Radio EQ update using the Digital Technician® II diagnostic tool is:
  • Recommended before speaker INSTALLATION
  • Required before audio system OPERATION.
  • Only available through authorized Harley-Davidson dealers.
WARNING
Rider and passenger safety depend upon the correct installation of this kit. Use the appropriate service manual procedures. If the procedure is not within your capabilities or you do not have the correct tools, have a Harley-Davidson dealer perform the installation. Improper installation of this kit could result in death or serious injury. (00333b)
NOTE
This instruction sheet refers to service manual information. A service manual for this year/model motorcycle is required for this installation. One is available from a Harley-Davidson dealer.
Electrical Overload
WARNING
When installing any electrical accessory, be certain not to exceed the maximum amperage rating of the fuse or circuit breaker protecting the affected circuit being modified. Exceeding the maximum amperage can lead to electrical failures, which could result in death or serious injury. (00310a)
NOTICE
It is possible to overload the vehicle's charging system by adding too many electrical accessories. If the combined electrical accessories operating at any one time consume more electrical current than the vehicle's charging system can produce, the electrical consumption can discharge the battery and cause damage to the vehicle's electrical system. (00211d)
This amplifier requires up to 8 amps more current from the electrical system.
The purchase of this kit entitles you to a specially developed sound equalization software that is used with the Advanced Audio System. This unique equalization was designed to optimize the performance and sound response of the BOOM! Audio fairing lower speakers. Even if this kit is not installed by a Harley-Davidson dealer, this special equalization software is available without charge from any dealer through Digital Technician II. Dealer labor rates may apply for the upgrade procedure.

Wiring Diagram Information
Wire Color Codes
For Solid Color Wires: See Connector/Wiring Diagram Symbols (Typical). The alpha code identifies wire color.
For Striped Wires: The code is written with a slash (/) between the solid color code and the stripe code. For example, a trace labeled GN/Y is a green wire with a yellow stripe.
Wiring Diagram Symbols
See Connector/Wiring Diagram Symbols (Typical). Brackets [ ] indicate connector numbers. The letter inside the brackets identifies whether the housing is a socket or pin housing.
A=Pin: The letter A and the pin symbol after a connector number identifies the pin side of the terminal connectors.
B=Socket: The letter B and the socket symbol after a connector number identifies the socket side of the terminal connectors. Other symbols found on the wiring diagrams include the following:
Diode: The diode allows current flow in one direction only in a circuit.
Wire break: The wire breaks are used to show option variances or page breaks.
No Connection: Two wires crossing over each other in a wiring diagram that are shown with no splice indicating they are not connected together.
Circuit to/from: This symbol indicates a complete circuit diagram on another page. The symbol is also identifying the direction of current flow.
Splice: Splices are where two or more wires are connected together along a wiring diagram. The indication of a splice only indicates that wires are spliced to that circuit. It is not the true location of the splice in the wiring harness.
Ground: Grounds can be classified as either clean or dirty grounds. Clean grounds are identified by a (BK/GN) wire and are normally used for sensors or modules.
NOTE
Clean grounds usually do not have electric motors, coils or anything that may cause electrical interference on the ground circuit.
Dirty grounds are identified by a (BK) wire and are used for components that are not as sensitive to electrical interference.
Twisted pair: This symbol indicates that the two wires are twisted together in the harness. This minimizes the circuit's electromagnetic interference from external sources. If repairs are necessary to these wires, they should remain as twisted wires.
