Wild Boar BIG-PIG-RG – 600W Amp + 4-Speaker Kit with 6×9" Saddlebag Lids for Road Glide 2015–2023
The complete plug-and-play 600W front and rear audio system for the 2015 to 2023 Road Glide
The Wild Boar BIG-PIG-RG is a complete four-speaker audio system for the 2015 to 2023 Harley-Davidson Road Glide®. It combines two 300W Class-D amplifiers, Road Glide-specific 6.5 inch front speakers, high-output 6x9 rear component separates, and genuine Hogtunes paint-ready saddlebag lids, all wired with a plug-and-play harness. It works with the factory Harley radio and needs no gain, crossover or EQ adjustment.
This is a whole system in one box, matched and tuned so you install rather than design. Everything is chosen to work together electrically and to fit the Road Glide, from the dual-amp plate behind the headlight to the crossovers under the lids.
Who This Is For
You ride a 2015 to 2023 Road Glide® and want a big, balanced front and rear upgrade that runs off the factory radio without tuning. The BIG-PIG-RG gives you 600W of matched amplification, four speakers and paint-ready lids as one integrated kit. If you want to build a system piece by piece around your own amplifier and speaker choices, the individual WBS 1694 rear speakers and lids are available separately.
What This Is Best For
- A complete Road Glide upgrade in one purchase. Front speakers, 6x9 rears, two amplifiers, saddlebag lids and harness are all included and matched, so there is no component research or compatibility risk.
- Factory-radio plug-and-play. The system runs from the factory HD radio with no gain, crossover or EQ setup, so it installs cleanly and works straight away.
- Balanced four-speaker staging. Road Glide-specific WBC 1654RG front speakers and 6x9 WBS 1694 rear separates give strong front and rear staging.
- Output within the factory charging system. Dual 300W amps with R.E.M.I.T. deliver big output without overloading the stock electrical system, and R.E.M.I.T. protects FM reception that Class-D amps can otherwise degrade.
Fitment and radio re-flash
The BIG-PIG-RG fits the 2015 to 2023 Road Glide FLTRX. It requires a Techno Research or OE dealer radio software re-flash to run correctly. A note on FM: Class-D amplifiers can reduce FM reception, and R.E.M.I.T. provides the best FM performance possible for motorcycle Class-D amps. A factory exterior antenna gives the strongest signal, and adding a third amplifier later increases FM interference, which is normal. Confirm your model and radio before ordering.
The Bottom Line
The Wild Boar BIG-PIG-RG is the complete, matched, plug-and-play way to transform a 2015 to 2023 Road Glide® with 600W of amplification, four speakers and paint-ready lids in one kit. Add it to cart above. For a bagger built around the same rear speakers on Hogtunes lids, the WBS 1694 speakers are also sold on their own.

How the system fits together
The kit runs two 300W Class-D amplifiers on a dual-amp plate that mounts behind the Road Glide headlight, feeding a Road Glide-specific 6.5 inch front pair and a 6x9 rear component set with crossovers under the lids. Because it is matched and pre-tuned, there is no gain or crossover setup. On the road: the front and rear stay balanced and the system plays clean at highway speed without any adjustment.
