Grand Cherokee L silence
"It is so nice I was able to 'easily' by-pass the junky ANC in my 2021 Grand Cherokee Long. The ANC did not create silence as one would expect, there was alway constant feedback in the stock sub and stock McIntsh system that made talking to people in the back seat difficult. With the T-Harness, once you get your hands dug into the quarter panel and installed, the minimal road noise you can here is much better than the weird feedback from the sub. I have not even added an additional compents for a stereo system. This was in my first order of parts after purchasing the vehicle, the other was the 4D Auto Stop/Start by-pass."
