I added this https://a.co/d/0dQW069r harnessfrom amazon. It connected to one of module behind glove box no splicing needed so you can remove it at any time if needed. After that you can add any amp you want with rca connector and remote wire. I added jbl monoblock with factory subwoofer in my 2021 model. I ordered factory oem subwoofer from Piazza VW of Langhorne for $282 back in 2024. Part number is 11A-035-621-A. They didn’t offer that woofer in NA region until MY2025 but fortunately they use same in audi e-tron. I go with oem subwoofer just because it fit perfectly and did’t use much space In fact it goes into charging cable compartment so no trunk space wasted. And for sound quality it definitely feels much better but don’t expect it to shake car windows with that oem woofer. I also changed adaptation to harman-kardon with odbeleven but it doesn’t really make any difference other than getting bit louder at higher volume.
