GROM Amplinq amplifier retrofit kit for factory JBL stereos of select Audi 2009-2017 without Navigation
Amplinq kit is the simplest way to upgrade your vehicle’s factory “Premium” audio system—without sacrificing any OEM functionality.
Modern premium systems already have speakers placed in the right locations, but they often lack the power and clarity needed for truly great sound. Amplinq solves this by allowing you to replace the factory amplifier with a more powerful aftermarket solution—while keeping everything else exactly as it was.
With our plug-and-play design, installation is seamless. All factory features remain fully functional through your original head unit, including chimes, navigation prompts, phone calls, and audio controls. No reprogramming, no rewiring, no compromises.
Once installed, Amplinq kit lets you:
All connections: speakers, subwoofers, tweeters, and power — remain intact using vehicle-specific matching plugs and harnesses.
Reusing factory locations and connectors makes sure you do not need custom fabrication. No visible modifications. No extra batteries or complex rewiring. Your interior stays 100% factory, just with dramatically improved sound.
Amplinq kit provides 7 channels ( 2 x front tweeters, 2x front woofers, 2 x rear woofers, 1 x subwoofer) of clean, fully tuned audio signal directly from your factory stereo to the speakers. It eliminates the need for LOCs, signal summing, or additional processing — preserving sound quality from start to finish.
Get a predictable installation procedure, controlled costs, and a system that looks stock, but sounds to your taste.
The connection diagram is shown below. Simple, affordable, and providing an exclusive sound you dreamed of.
