Add more Boom! to your bike. This kit permits the addition of a third or fourth pair of speakers to your Boom! Audio-equipped Touring bike. Choose a combination of Boom! Audio Fairing Lower Speakers and/or Rear Speaker Pods (sold separately) to build a sound system custom-designed to your audio demands. System also provides speaker fade capabilities between fairing and non-fairing mounted speakers for highway riding, when it's needed most. Kit includes 75-watt/channel (300-watts total) saddlebag-mounted amplifier, amplifier cover, mounting bracket and the required installation hardware and wiring harness. Note: The use of the Boom! Audio Amplifier turns off the radio's internal amplifier.
