2016 Hyundai Gene Sedan Sub install Help

[Tbone2299]

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.

I have not added an aftermarket subwoofer myself to my 2015, but have considered just unplugging the rear deck sub and tapping its signal to a high wattage input line out convertor so that I can add an aftermarket digital amp and subwoofer in future. In theory it should work.

I would use a line convertor similar to this or better that can handle high wattage input from a factory amp. However, we will need a convertor that also creates a remote amp turn signal for the aftermarket amp.
