HRS-RK-624.4 NEO Immersive System for Road King

The HRS-RK-624.4 NEO Immersive System for Road King combines Aquatic AV’s GP1 Bluetooth head unit, Havoc’s exclusive 3.5" handlebar speaker system, and 480W NEO 6.5" highway bar speakers, all tied together with a 600W Aquatic AV amplifier in the saddlebag.

Four speakers, two zones, one brutally capable Road King front stage.

• 600W Aquatic AV amplifier in the saddlebag driving the NEO highway bar speakers properly
• All wiring and hardware included – engineered specifically for the Road King platform
• No fairing, no giant bagger build-out—your Road King still looks like a Road King
• Ideal for loud exhausts, fast riding, and riders who actually use the right-hand grip

System Components

Aquatic AV GP1 in a billet housing

• Bluetooth® audio streaming from your phone or device, plus AM/FM, USB playback, and Sirius/XM Satellite Radio using the app on your phone
• Simple, glove-friendly controls so you’re not hunting tiny buttons
• Designed for the motorcycle environment: weather-resistant and built for vibration

Exclusive 3.5" Handlebar Speaker System

• Waterproof speakers built by Aquatic AV exclusively for Havoc Motorcycles, driven directly off the GP1’s internal 288W amplifier
• The biggest magnet that will fit on a 3.5" speaker for real output in a tiny package
• Full aluminum basket resists flex and stays solid under vibration
• Billet housings that echo the “spear” lines of the nacelle for a factory-integrated look

6.5" Highway Bar Speakers in Billet HRS Pods – NEO Upgrade

Saddlebag Amplifier Mounting & Hardware

• Havoc’s engineered Roadlock saddlebag bracket locates the amp securely inside the saddlebag
• Keeps the amplifier protected, out of sight, and out of the weather
• Leaves usable luggage space while giving the amp the airflow it needs

Complete Wiring & Hardware Package

• Power and ground wiring sized correctly for the load and length on a Road King
• Speaker harnesses, connectors, terminals, AM/FM antenna, and stainless hardware
• Inline storage on/off switch so your existing accessory wiring under the seat and nacelle toggle can remain available for your existing accessories

Fitment & Compatibility

• Designed specifically for Harley-Davidson Road King models, with fitments for 1998–2013 and 2014–present
• Available in chrome or black billet highway bar pods to match your bike’s theme
• Handlebar speakers work with bars that use the factory clamp (not compatible with t-bars)
• Highway bar pods are designed to clamp to OEM-style engine/highway bar configurations
• No front fairing required—the system is built around the Road King’s naked front end so your Road King keeps looking like a Road King
