In practice, the speakers are underpowered, the bass is thin, and road noise competes with everything above 60km\/h.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSystem One addresses the fundamentals without touching the factory head unit or disrupting anything that already works. A compact underseat subwoofer fills the low-frequency range the standard system can't reach. Sound deadening across the front doors — and rear doors where applicable — reduces road noise and gives each speaker a properly sealed environment to work in. In the EV6, EV9, and Tasman, where the cabin character varies significantly by variant, the difference is immediately audible.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFor Kias on the standard 6-speaker configuration – which covers the majority of models and trims – a two-channel amplifier driving the factory speakers adds power and control before the signal even reaches the subwoofer. The result is a system that feels significantly more capable without looking or behaving any differently.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSYSTEM ONE INCLUDES:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCompact underseat subwoofer\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSound deadening — front doors (all four doors where applicable)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTwo-channel amplifier\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePower kit, cables and minor parts\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInstallation and calibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePricing depends on your model and configuration — contact us for a quote specific to your Kia.\u003c\/p\u003e","brand":"rapid-radio","offers":[{"title":"Default Title","offer_id":45034376200400,"sku":null,"price":0.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/3351\/3168\/files\/KiaSYSTEMONE.png?v=1780884808","url":"https:\/\/www.rapidradio.co.nz\/products\/kia-audio-upgrade-system-one","provider":"rapid-radio","version":"1.0","type":"link"}
