Review on 🔌 Enhance Your Volkswagen Audio Experience with 4 Pack Speaker Wire Harness Adapter Replacement - VW Jetta GLI GTI Beetle Golf Passat Polo Speaker Connector Harness Adapter by Justin Gore

These adapters connect to a 2017 Jetta SE with basic audio. However, the polarity is reversed. Simple solution. Drag the pins and flip them over. Warning for people with limited car audio knowledge. It is important to note the polarity. Proper phasing gives your system a fuller sound. Reverse polarity will cause your speakers to move in the opposite direction when powered on. In a very simple 4-speaker system, it doesn't matter. However, if your system is expanded, perhaps with a subwoofer or additional speakers, polarity does matter. In general, you want your system to be the same in every way. Audiophiles may disagree with that statement, but I don't talk to them. This is for all the people who just want to rejuvenate this crappy sounding factory system a bit lol. These adapters are perfect for replacing factory VW speakers with aftermarket speakers. But you have to exchange contacts.
