Audi A1 (2010 - 2026) Plug and Play 2-Channel Line Output Converter

Upgrade your factory audio system in your Audi A1 the right way with this vehicle-specific plug-and-play T-Harness. Designed for seamless integration, this harness allows you to add an aftermarket amplifier or DSP without cutting, splicing, or modifying your factory wiring loom. Installation is quicker, cleaner, and completely reversible — making it the perfect solution for professional-quality upgrades.

This harness is available with three premium line output converter options from Kicker and Wavtech, widely regarded as two of the most advanced and reliable LOC manufacturers in the industry.

Standard Option - Kicker KISLOC
The Kicker KISLOC is a speaker level to RCA converter with remote turn on wire. Unlike traditional LOCs, the KISLOC2 is designed without inductors to deliver a completely flat frequency response at all volume levels.

Premium Option – Wavtech LINK2
The premium option includes the Wavtech LINK2, a high-performance 2-channel line output converter with remote output. It delivers a clean, powerful signal to your aftermarket amplifier while maintaining exceptional sound quality and reliability. It also features adjustable gain control, allowing you to provide your amplifier with a strong, distortion-free signal — meaning the amplifier gain can be kept lower for cleaner overall performance and reduced noise.

Premium Plus Option – Wavtech LINKDQ
For the ultimate factory integration solution, choose the Wavtech LINKDQ. In addition to all the performance benefits of the LINK2, the LINKDQ features a built-in parametric EQ specifically designed to optimise low-frequency response.

This is especially beneficial when adding a subwoofer amplifier to a factory system. The parametric EQ allows you to:

• Select frequencies between 20Hz–80Hz

• Apply up to 12dB of bass boost

• Correct low-frequency roll-off commonly found in OEM audio systems

The result is deeper, more controlled bass and dramatically improved low-end performance.

Vehicle compatibility:

• Audi A1 2010 - 2014

• Audi A1 2015 - 2018

• Audi A1 2019 - 2026

• For basic audio systems only. Not compatible with Bose vehicles

Why Choose Our Harness Over Cheaper Alternatives?
There are other T-harness solutions on the market, but the difference comes down to the quality of the line output converter. Kicker & Wavtech products are engineered for superior sound quality, reliability, and installer-friendly features that many cheaper LOCs simply do not offer.

Key Wavtech Features:

• Variable gain adjustment with clip indicators

• Automatic turn-on via DC Offset or Signal Sense

• Built-in speaker load circuitry

• Differential balanced inputs

• Ultra-low impedance RCA outputs

• Professional-grade panel-mount RCA connections

• Compact aluminium chassis design

What Makes These Features Important?

Variable Gain Adjustment with Clip LEDs
Instead of relying solely on amplifier gain controls, which can often introduce unwanted noise, Wavtech LOCs allow you to properly set signal level at the source. The integrated clip LEDs make setup simple and accurate, helping achieve maximum clean output with minimal distortion.

Built-In Speaker Load Simulation
Many modern factory audio systems monitor speaker resistance. Removing factory speakers or integrating aftermarket equipment can sometimes cause audio muting or warning issues. Wavtech’s integrated loading circuitry prevents this by maintaining the correct load on the factory system.

Differential Balanced Inputs
Balanced inputs help reject electrical interference and noise, resulting in cleaner audio performance and improved signal integrity.

Low Impedance Outputs
With output impedance below 50Ω, Wavtech LOCs provide a strong, noise-resistant signal capable of driving aftermarket amplifiers to their full potential.

Professional Panel-Mount RCA Connections
Unlike basic PCB-mounted RCA sockets, panel-mount RCAs provide a tighter, stronger, and more reliable connection — ideal for long-term durability in automotive installations.

Compact Aluminium Chassis
The robust aluminium casing improves durability while keeping the unit compact enough for discreet installation behind radios.
