Havoc Roar Stereo HRS-ST-624.4 Softail 4-Speaker Immersive System
4 Speaker, 3.5" Bars + 6.5" Neo 480W / 624W System
There’s a moment on every ride when the world goes quiet in your helmet and it’s just you, the bike, and the song that came on at exactly the right time.
This system is built for that moment—over and over again.
The HRS-ST-624.4 takes everything people love about a 4-speaker Softail setup and turns it up a notch. Compact 3.5" billet handlebar pods put the vocals and detail right in front of you, while a pair of 6.5" highway bar pods loaded with Aquatic AV HS.116 480W Neo speakers do the heavy lifting down low. A 600W Aquatic AV amplifier hidden in your saddlebag on a custom Havoc Roadlock Softail bracket gives the whole system real headroom, so when you roll on the volume, it doesn’t flinch—it just gets bigger.
High-efficiency Neo drivers, proper power, and real tuning mean this isn’t just “loud.” It’s strong, controlled sound at real Softail speeds—clean mids, crisp highs, and enough punch to make the miles disappear.
The Head Unit Front and Center
This isn’t a hideaway ‘mystery box’ buried in a saddlebag where you hope everything is working.
The Aquatic AV gauge stereo sits right on your handlebar clamp, in a billet pod that looks like it belongs there. You can glance down and see your station, track, and volume. You’ve got a real display, real buttons, and a volume control you can reach with gloves on.
You get AM/FM radio, Bluetooth® audio streaming, USB playback, and app-based SiriusXM® in a package that looks like a factory gauge upgrade—not an afterthought. All the brains are in front of you, where they should be, so you’re in control of the soundtrack, not guessing what a hidden module is doing.
On the Road
Out on an empty stretch, the 3.5" pods carry the vocal right to you—clear, centered, and easy to hear over the wind. The 6.5" Neos on the highway bar fill in everything underneath: drums, bass, guitars that sound like they’re out in front of the bike instead of trapped in a fairing you don’t have.
Roll into traffic, roll back out onto the open road, ride into the evening—this system just stays with you. Turn it up for a long highway pull and it doesn’t go harsh or fall apart. The Neo drivers and 600W of power keep it composed, like a good motor that still feels smooth when you twist the throttle.
