Description
SEAT Leon Mk3 Sound System wiring loom for supported 2014–2020 vehicles. This wiring kit connects the Sound System subwoofer and centre dashboard speaker to a compatible infotainment system.
What is supplied?
- Subwoofer wiring loom
- Centre-speaker wiring loom
- Plug-and-play Quadlock adapter
The kit costs £180 excluding VAT. It is a new wiring kit, not a complete Sound System retrofit. The speakers and subwoofer are not included.
Installation and coding requirements
The loom is designed to avoid cutting, soldering or joining the factory wiring and allows a reversible installation on supported cars. Compatibility must be checked against the vehicle and infotainment system before purchase.
The infotainment needs suitable coding and the correct sound-system dataset. Coding, dataset configuration and workshop fitting are charged separately. Fitting takes approximately one hour where the vehicle and parts are suitable.
Need the complete retrofit?
See our SEAT Leon Mk3 Sound System retrofit for the complete parts, fitting and coding package at our Redditch workshop.
Confirm compatibility
Send your VIN and fault details and details of your infotainment system and the sound components you have. We will confirm suitability and any separately priced workshop work. See our workshop services for other retrofit options.
