This harness connects to one of our radio specific T harnesses. In most cases it provides a speaker level input that germinates in RCA. Depending on your amplifier you might need a high to low converter. We recommend The Kicker KeyLoc because it has a built in bass restoration sound processor.

My wife got me a Atoto stereo for Xmas, I couldn’t find anywhere that done a harness that would allow me to use my steering wheel functions and stop battery drain.
Found Enfig and they were fantastic! Christian talked me through exactly what I needed and then ordered everything via their website, very comprehensive to put together and solved all my issues with their product!
10/10 service and product!
Highly recommend Enfig to all Golf GTI mk5 owners who are looking for a great product service!

I purchased the PNPAMP-EURO16 (Kicker Key 200.4 + plug and play harness) for my 2020 Passat and couldn't be happier. Made a huge difference in sound quality and clarity. The custom harness is truly plug and play and took no time and very little effort to install. I strongly recommend Enfig to anyone wanting a quality product, these guys are the best!

I purchased a Ram retro-fit microphone. Great item. Installed easily and fit as described. The video was helpful. Sound quality is also much better. Thank you.

This is the only place you should be going to in your R8 for a modern century radio/head unit. Amazing car, awful radio.
Christian is a true perfectionist and it shows in his work. Gorgeous job on my new Sony XAV-AX6000. It looks stock which was extremely important to me. Kept the factory backup camera and works perfectly. Christian even custom programmed the wheel buttons to my needs. It has the gauge read out via obd2 on the Somy screen which comes on with a button on the wheel, so cool.
It picks my phone up on Apple play before the car comes off idle. Incredibly fast radio start up. It also has buttons!! Estoy muy veijo. Yo me gusto buttons!
Christian get ready for my wife’s Accord. She wants the Sony in her car now.

The Enfig mic for my 2008 911 was just awesome! I watched the videos on the Enfig website abbnd a very simple install. My comparison calls with the mic that came with the head unit I had installed by someone and the new Enfig mic, no doubt the Enfig.mic in the stock factory position was much clearer and better volume reported on the other end. Definitely glad I made the switch for the hidden position and got better performance as well!

The kit I purchased was complete, well instructed, and resulted in a clean fit and appearance!

Christian is a thoughtful, careful, and all around high-quality stereo guy. He installed a new system in my 996 in no less than 1 day’s time. Would recommend!
