Want a better system?
The Cicada Audio 14FLXCX-4X2 delivers 500W, cleaner highway-speed output, and a purpose-matched amp and speaker combination for Street Glide (2014–2023) — more headroom, less compromise than this package.

The Wild Boar WBASG-KIT.2R is a complete plug-and-play front-stage audio upgrade for 2014–2024 Harley-Davidson® Street Glide, Ultra Limited, Ultra Classic, and Tri Glide Ultra models. The kit pairs a WBA 400.2R 2-channel Class-D amplifier with WBC 1654 6.5″ front speakers, with everything required for installation included — amplifier, speakers, mounting plate, and wiring harness — and no wire cutting required.
Who This Is For
Street Glide, Ultra, and Tri Glide riders on 2014–2024 models who want a meaningful step up from factory audio without a complex multi-amp installation. The WBASG-KIT.2R is a self-contained 2-speaker front-stage system — strong, FM-friendly, and straightforward to install. The kit includes a mounting plate and harness for a second amplifier when you're ready to expand, and a third amp is possible with the optional FLH Side Plate-RM. For a complete front-and-rear 4-speaker upgrade from the start, see the WBA RETRO 800.4SG.
What This Is Best For
- FM radio listeners — The WBA 400.2R uses Wild Boar's proprietary R.E.M.I.T. (Reduced Electro Magnetic Interference Technology) to minimise the FM reception degradation that all Class-D motorcycle amplifiers produce. If FM is a regular part of your ride, R.E.M.I.T. is a genuine real-world advantage over standard Class-D designs.
- Clean plug-and-play installation — The kit uses a 100% plug-and-play wiring harness with factory-fit Harley connectors. No wire cutting, no splicing. The amplifier mounts on the supplied plate inside the batwing fairing without relocating any factory components.
- Broad model compatibility — One kit fits Street Glide, Ultra Limited, Ultra Classic, Tri Glide Ultra, and Street Glide Standard across the 2014–2024 model range — a single SKU covering the full batwing fairing platform.
- Expandable system architecture — The kit ships ready to accept a second WBA 400.2R amplifier. A third amplifier can be added using the optional FLH Side Plate-RM mounting plate, allowing the system to grow to over 1,200 watts without relocating hardware out of the fairing.
Considering a Cicada system instead?
If you're weighing this kit against the Cicada Audio front-stage range, read our full head-to-head comparison: Cicada Audio vs Wild Boar Audio: Harley Touring Sound Compared. It covers power ratings, expandability, impedance, FM reception, and the real cost of going from 2 to 4 speakers with each system.
The Bottom Line
A well-built, FM-friendly plug-and-play front stage for batwing fairing riders who want strong performance and a clean installation. The R.E.M.I.T. amplifier is the standout feature — if FM reception matters to you, it's the most important difference between this and standard Class-D motorcycle amps.

Radio Flash — Required Before Installation
A TechnoResearch or Harley-Davidson® dealer radio software re-flash is required before installing this system. Factory Harley Infotainment firmware applies EQ curves, dynamic compression, and output limiting designed around stock speakers — these remain active after an amplifier is installed and will significantly reduce the performance of the WBASG-KIT.2R. The flash takes approximately 30 minutes. See your local dealer or TechnoResearch for pricing.
R.E.M.I.T. Technology
All Class-D amplifiers generate electromagnetic interference that reduces FM radio reception — this applies to every brand and every Class-D design. Wild Boar's R.E.M.I.T. (Reduced Electro Magnetic Interference Technology) is a proprietary circuit included in the WBA 400.2R that minimises this interference, delivering better FM performance than standard motorcycle Class-D amplifiers. Adding a second or third amplifier to the system will increase FM interference — this is normal and expected with any multi-amp configuration. For best FM performance, retain the factory external antenna rather than using an in-fairing antenna.
