I have searched here and anywhere else I can find. Does anyone have the exact procedure to install an aftermarket sub/amp into the 2016 Genesis with the ultimate package? Looking to connect into the stock amp. I would be very appreciative of any support. Sorry if I missed an obvious thread with this but everything seems to have every option but my year and from what I am reading, it seems that there are several options that need to be considered when jacking into the stock amp. Thank you in advance.
