Ordered an amplifier with a plug and play harness from Enfig and I couldn't be more satisfied with the results after installation. Shipment was fast and helpful instructions were included from the owner. I definitely recommend this company!

I found Enfig Car Stereo through a YouTube video explaining the exact system that was going into my wife’s car. I reached out and found out not only did he produce a custom harness so I could hook up the amp with no wire splicing, simply plug and play but he also went above and beyond on the install. He made custom 3D printed mounting rings for all 4 door speakers and tweeters! He tuned my kicker key amp, set gains and all. Everything fits and works perfectly and I couldn’t be happier. I’m coming back for my sub install. Can’t recommend him enough.

Enfig has the wire adapter that the other major car stereo place does not offer. I emailed my needs and got a nice detailed list of everything I need with links. The wiring harness is literally plug and play without any wire splicing. The adapter kit is much nicer too and blends in nicely with the factory trims.

I received this item for my e46. Shipping was crazy fast super easy install. Couldn’t be more stoked on the results. I ran into one issue but their tech support solved it right away over the phone. 10/10 recommend.

Never heard of the company before but they made a high quality Aud/VW quadlock T-harness. Delivered super fast.

Ordered some car audio parts from these guys. Amazing service, kept me informed of the status of my order the whole way through the back order process. Super quick international shipping. I will definitely deal with them again, and highly recommend them.
