Wild Boar – Dual 300W Amps + 4-Speaker Kit for Ultra Limited, Ultra Classic & Tri Glide Ultra (2014–2023)
The Wild Boar 300W x 4-Speaker Kit is a full front and rear audio upgrade for 2014–2023 Ultra Limited, Ultra Classic and Tri Glide Ultra models. Featuring two 300W Class D amplifiers, 200W front speakers, 150W rear speakers and a complete plug-and-play wiring system, this kit delivers strong, clean output with perfect OEM-style fitment.
Designed specifically to work with the Harley-Davidson® factory HD radio and charging system, this setup offers a big improvement in clarity and volume without requiring complex tuning or adjustments.
Who This Is For
- Riders on 2014–2023 Ultra Limited, Ultra Classic or Tri Glide Ultra models that already have factory rear speaker pods.
- Anyone wanting front and rear speakers plus amplification in one kit while keeping the factory HD radio.
- Riders who want a plug-and-play result with no gain, crossover or EQ adjustments to make.
- Bikes still running the original non-amplified factory 4-speaker profile, which need no radio re-flash.
- Riders who accept that Class D amplifiers reduce FM reception, with Harley’s external antenna giving the best FM performance.
Key Features
- Two 300W Class D amplifiers (600W total system power) with R.E.M.I.T. for improved FM reception.
- WBC 1654 6.5" front speakers engineered to blend perfectly with the Ultra batwing fairing.
- 150W rear speakers designed to fit precisely into OEM Harley rear speaker pods.
- No gain, crossover, or EQ adjustments – plug-and-play simplicity.
- Complete wiring harness with Harley-specific connectors.
- Amp mounting plate included for correct fairing installation.
- Expandable system – supports lower fairing speakers or saddlebag lid upgrades later.
- Components tuned for motorcycle acoustics to stay clear at highway speeds.
Why Riders Choose This Kit
- Dual-amp architecture provides strong, clean front and rear output.
- Factory-style integration with big audio performance.
- Perfect for Ultras already set up with factory rear pods.
- Simple installation – especially when the factory 4-speaker profile is still active.

Technical Notes
- No radio re-flash required if the bike still has the original non-amplified factory 4-speaker profile.
- Class D amplifiers naturally reduce FM reception – this is normal across all brands.
- R.E.M.I.T. circuitry provides the best FM performance available for motorcycle-specific Class D amps.
- Adding additional amplifiers will further reduce FM reception – this is expected.
- Harley’s external antenna always provides the best FM performance.
