Myself (InTune Customs) and Jon Cain (ATA KC) teamed up to design a brand-new OEM Integration Harness that makes audio installs plug-and-play on Yamaha Jet Boats.
Yamaha Cabin Amplifier Harness – $150
Additional Yamaha Applications
These harnesses are designed to save time, avoid cutting into factory wiring, and give you a clean, OEM-style upgrade path. Whether you’re adding power now or planning a full system overhaul later, this harness supports both.
DM me here or reach out directly to @InTune Customs or 724-884-6120 for ordering and details.




- New dual-function design – use the same harness to add an amp OR replace your factory amp
- Includes both input & output harnesses
- Built for HTX 4/6 DSP OE Amplifiers
- Two configurations:
• Add-On Mode – Keep your stock amp and expand your system
• Replacement Mode – Fully replace your stock amp; plugs directly into the factory speaker wire harness for a clean install

- New AR Boats (Silver Amps) – Harnesses/packages available for amp replacement
- Yamaha with Hertz Amps – Supported as well, though these setups aren’t fully standardized (please inquire)
