For JBL-equipped models, this is where the nine-speaker hardware finally gets what it needs. For standard models, this is where the Hilux stops sounding like a work vehicle and starts sounding like a proper listening environment.\u003c\/p\u003e\n\u003cp\u003eOn most Hilux models up to and including the 2024 generation, we may recommend a head unit replacement as part of the System Two build — it gives us a cleaner signal chain and a better overall result. On 2025 facelift and new-generation models, the DSP connects directly to the factory signal chain. Either way the outcome is the same — complete independent control over every speaker in the vehicle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSYSTEM TWO INCLUDES:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e- Compact underseat subwoofer\u003cbr\u003e- High-fidelity tweeter and crossover upgrade\u003cbr\u003e- Multichannel DSP amplifier\u003cbr\u003e- Full individual speaker timing, phase and EQ calibration\u003cbr\u003e- Sound deadening — front doors\u003cbr\u003e- Power kit, cables and minor parts\u003cbr\u003e- Installation and calibration\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHOW THIS SYSTEM WORKS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe multichannel DSP amplifier is the heart of System Two. It takes the signal from the factory head unit and processes it independently for every speaker in the vehicle — correcting timing, phase, and equalisation channel by channel. This addresses the acoustic problems that every vehicle cabin creates and that no factory EQ can fix. In a Hilux cab, where road noise and panel resonance already compromise the listening environment, independent per-speaker control makes a significant audible difference.\u003c\/p\u003e\n\u003cp\u003eThe DSP also cleans the signal. The Hilux factory head unit provides a speaker-level output rather than a clean line-level signal — the DSP processor corrects this before it reaches the amplified channels, resulting in significantly lower distortion and better dynamic range across the full volume range.\u003c\/p\u003e\n\u003cp\u003eFor JBL-equipped models, the nine-speaker system is capable of significantly better performance than the factory amplification allows. Independent EQ control over the tweeters, door speakers, and subwoofer separately — rather than the blunt bass and treble controls in the head unit — transforms what the JBL hardware actually sounds like.\u003c\/p\u003e\n\u003cp\u003eThe system is calibrated using professional, specialist software — precise independent control over every parameter. Once set, the factory head unit's bass and treble controls still allow smaller on-the-fly adjustments. Wired remote controls are available for most of our DSP amplifiers and subwoofers.\u003c\/p\u003e\n\u003cp\u003eSuitable for all Hilux grades and generations but particularly recommended for JBL-equipped models.\u003c\/p\u003e\n\u003cp\u003ePrices vary based on model year, factory audio configuration, and component choices — contact us for a quote.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45026478915792,"sku":null,"price":0.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/3351\/3168\/files\/HILUX_Audio_System_TWO.png?v=1779926297","url":"https:\/\/www.rapidradio.co.nz\/products\/toyota-hilux-audio-upgrade-system-two","provider":"rapid-radio","version":"1.0","type":"link"}
