Two years old, Helix sub-woofer for VW golf years 2010-2015. It’s a plug and play upgrade to the audio in non-SEL models. When installed it sits in the spare tire well. Plenty of YT videos on installation. It probably works in other models but I haven’t looked into it.
I replaced my Golf SE with an SEL and decided not to try to modify the wiring even though I think it’s a better sub than the one VW/Fender use in my car.
Comes with programming dongle interface.
