Add sub to factory Lexicon system

[takenotes]

I have a 2012 with the technology package and honestly I really like the factory Lexicon system (by far the best factory system I have had yet), but sometimes I really miss having deep bass as most of my cars have always had at least a single 12 inch installed. I have a buddy that has always installed and tuned my systems for me so install shouldn't be much of an issue. My question is mainly what would I need to do in order to add a single 12 and amp to the factory system to extend the bass capabilities? Also, I have always went with Kicker CVR's or similar in the past, but I don't want to completely drown out everything with bass, didn't know if anybody had any recommendations as to decent subs that won't be too overkill for the factory speakers. Any advice and/or input would be appreciated.

I believe many people have done this by simply splicing into the factory sub wires and run a high level signal to the additional subwoofer amplifier. The battery being in the trunk makes the power situation quite easy. I have also read that the stock sub amplifier sends a very healthy (even maybe down to 20hz) signal so taping into this signal from the stock sub is a great option.
The Genesis is quite sealed up so I would say a nice 10 or 12inch sub would be plenty to add the needed thump to the stock system. Much more than that and you would simply have to keep it turned way down

I have a 2011 Genesis Prada. I added 2 kicker comp r's in a dual ported box powered by a RF amp amd it sounds absolutely amazing. The lexicon 17 speaker system is more than adequate for my mids and highs. Definitely a great addition...cheers.
