WBA 400.2R 400 Watt 2 Channel Amplifier

WBA 400.2R 400 Watt 2 Channel Amplifier

  • New smaller physical size now allows for up to 3 amps to fit inside the fairing (can build up to 1200 watts total)
  • New "DC Sensing" eliminates requirement for remote turn on lead
  • 100% Plug and play wiring is included
  • Supplied wiring and mounting plates allows easy addition of a 2nd WBA 400.2R amplifer
  • Hogtunes FLH Side Plate-RM and FLTR Side Plate-RM allow a 3rd WBA 400.2R to be added
  • 3 Year warranty
  • Drag Specialties part # 4405-0653


Note: The WBA 400.2R amplifier is a Class D design. It should be understood that ALL Class D amplifiers, regardless of brand, cause a reduction in FM reception. The WBA 400.2R features a proprietary circuit design called R.E.M.I.T. (Reduced Electro Magnetic InterferenceTechnology) that Hogtunes believes gives the BEST FM reception available for any Class D Amplifier designed for a motorcycle.If you add a 2nd or 3rd model amplifier to your system, reduction of FM reception is increased and is considered normal.


Hogtunes understands that some riders prefer the cosmetics of in-fairing antennas, however it should be noted that NOTHING works as well as the factory antenna. If FM is an important part of your riding experience, we strongly advise against the use of any in fairing type antenna!
