Motorcycle Audio New Zealand

Tunex Audio provides premium motorcycle audio upgrades in New Zealand, specialising in Harley touring models and high-output sound systems built for real riding conditions. If you want clean volume on the motorway, strong midbass without harshness, and bass you can actually feel, our motorcycle-specific systems are designed to deliver refined sound at speed while keeping reliability and factory integration front and centre.

Harley Touring Audio Upgrades Built for Modern Models

Harley touring motorcycles have changed dramatically in recent years, especially 2023.5 and newer models with factory Rockford amplifiers and the latest infotainment systems. Tunex Audio has experience with 2025-plus Harley touring models and understands how the factory audio behaves across different configurations, including CVO, Trike, bikes with a Tour-Pak, and bikes without one. We work with both GT and GTS factory radios and can upgrade every level of factory system while maintaining correct signal structure, proper tuning, and stable performance.

Saddlebag Subwoofers and Lid Speaker Upgrades

If you are chasing stronger low end without sacrificing clarity, saddlebag subwoofers are one of the most effective upgrades for touring bikes. We design and install systems that add subwoofers to the saddlebags and can also fit 6x9 speakers into the saddlebag lids for higher output and wider coverage. The result is fuller sound, improved projection, and a system that stays musical even when you turn it up.

High-End Motorcycle Audio Brands from the USA

Tunex Audio gives New Zealand riders access to high-quality motorcycle audio brands commonly used in top-level builds overseas. We source and install proven products and integration solutions from leading brands including Cicada Audio, Hertz, Soundigital USA, Ground Zero, NVS Audio, A2B Interfaces, and custom bass knobs. This gives you better reliability, stronger output, and cleaner signal control compared to generic upgrades.

Factory Integration and Expert DSP Tuning

Modern Harley audio upgrades require more than installing louder speakers. The factory processing, factory amplifier behaviour, and integration points all affect final sound quality. Tunex Audio provides expert advice and professional installation with DSP-based tuning where required. Our approach focuses on clean signal, correct crossover strategy, safe gain structure, and real-world tuning for wind noise, riding speed, and exhaust volume.

If you run an aftermarket exhaust, you know how quickly it can mask midbass and lower vocals at highway speeds. A properly designed system with high-powered amplification, DSP tuning, and appropriate electrical support can maintain clarity and output so your music stays dominant even when the bike is loud.

Battery and Electrical Upgrades for Reliable Output

High-output motorcycle audio systems demand stable voltage and proper current support. Where needed, we provide stronger battery upgrade options and electrical recommendations to ensure your system performs consistently and safely. This improves reliability, reduces distortion at high volume, and helps protect your equipment long-term.

MECP Certified Installation and Industry-Level Training

Tunex Audio’s lead installer, Vasu Berry, is an MECP Certified Installer and has been trained by Carlos Ramirez of NVS Audio USA, one of the industry’s most respected installers. This training and hands-on experience gives you confidence that your Harley audio upgrade is approached with correct methods, professional workmanship, and the tuning knowledge required to make the system sound refined, not just loud.

Motorcycle Audio That Sounds Clean Parked or Cruising

Some systems sound impressive in a parking lot but fall apart on the road. Tunex Audio designs motorcycle audio upgrades to perform in both environments. Whether you are parked up with friends or cruising on the motorway, our goal is clean, refined sound with strong presence, controlled bass, and high clarity at real riding speeds.
