Yamaha Owners – New Plug-and-Play Audio Harness
Hey everyone,
Just wanted to share something new we’ve been working on that should make life a lot easier for anyone upgrading their audio system in a Yamaha Jet Boat. Myself (InTune Customs) and Jon Cain (ATA KC) teamed up to design a brand-new OEM Integration Harness that takes the hassle out of DIY installs.
Cabin Amplifier Harness – Intro Pricing $150
Other Yamaha Applications
The goal with these harnesses is simple:

- Dual-function design → one harness can do both:
• Add-On Mode – keep your stock amp and expand your system
• Replacement Mode – fully replace your stock amp while still using the factory speaker harness - Packaged with both input & output harnesses
- Designed for HTX 4/6 DSP OE Amplifiers
- 100% plug-and-play – no cutting or splicing into factory wiring

- New AR Boats (Silver Amps) – We make harnesses/packages to support these newer setups
- Yamaha with Hertz Amps – Supported as well (though not as standardized, so reach out with details before ordering)

- Make installs cleaner
- Keep your factory wiring intact
- Give you the flexibility to upgrade in stages (add power now, replace later)
