Models
For model fitment information, see the P&A retail catalog or the Parts and Accessories section of www.harley-davidson.com (English only).
NOTE
For vehicles equipped with a Telematic Control Unit (TCU), use kit 76000278A in conjunction with this instruction.
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 your year/model motorcycle is required for this installation. One is available from a Harley-Davidson dealer.
Electrical Overload
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)
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 a Harley-Davidson dealer does not install this kit, this special equalization software is available without charge from any dealer through Digital Technician II. Dealer labor rates could apply for the upgrade procedure.
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)
This amplifier requires up to 8 amps more current from the electrical system.

NOTE
  • FLHX models: If this installation adds an amplifier to previously installed speakers, see the "Upgrade" section for wire harness connection instructions.
  • If this amplifier is used with a secondary amplifier to enable six or eight speakers, see connection details for [162] and [313] in Table 1 , Table 2 and kit 76000280. FLHX(S) [162] (F) a 4-way Molex rear channel output from radio. Used for speaker output without amp. See Figure 8. Unused with primary amp, used for secondary amp INPUT. See Figure 10. FLHTC/FLHTK/TRIKE [162] (R) a 16-way Molex rear channel output from radio. Contains all rear speaker pod wiring. Install 69200714 to use with amplifiers (see Step 7). Fairing Amp [313] a 4-way Molex rear channel output of the primary amplifier, can be used for saddlebag speakers, rear pods or fairing lowers. Reserved for fairing lowers when used on six or eight speaker configuration.
