Installation Requirements
Prior or concurrent installation of a fairing-mounted amplifier is required for proper installation of this kit. See the P&A retail catalog or the Parts and Accessories section of (English only) for Audio Amplifier Kit part numbers and fitments.
In these instructions: the Harman-Kardon® amplifier (fairing mount) is considered the "primary" amplifier. The saddlebag-mounted amplifier is referred to as the "secondary" amplifier.
FLHTKSE and FLTRUSE models require separate purchase of 69200714.
This kit is not compatible with premium bag liners. Fitted saddlebag linings require trimming to accommodate amplifier mount and harness cover.
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)
This instruction sheet references service manual information. A service manual for this year/model motorcycle is required for this installation and is available from a Harley-Davidson dealer.
The purchase of this kit entitles you to a specially developed sound equalization software that is used in conjunction 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.
Electrical Overload
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)
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)
The amplifier installed with this Amplifier Expansion Kit requires up to 8 amps additional current from the electrical system.
