Honestly I wish this were something dealers offered instead of some of the other markups they put on a car. I have added an aftermarket amp/sub to my last two Genesises (Genesii?) and took it to professional audio installers each time (Fry's Audio on one occasion and Best Buy on the other); it ended up being an all-day affair for each and neither had ever touched a Genesis before. It turned out okay in the end, but both commented that there was something unexpected that they ran into, and if my memory isn't failing me, I believe it was the same issue the OP's installer ran into: finding a good output signal.
You are correct. Finding the output IS the key. It only SOLID way is with the manual to find the right wires on the amp connector. That's how I did mine and got it in one.
Could you please post some pics of your new sub woofers??? Thanks in advance
Will installing an after market sub void the warranty ? if you have a warranty .

My setup:
Sub: JL Audio CP110LG-TW1
Amp: Memphis Audio 16-SRX1.250

Fantastic bass (clean, precise but weighty, VERY space efficient (lots of trunk space left). I tried a 10" Pioneer box but it did not sound very good but it was tiny (it was a sealed enclosure). I tried a custom built box with a Memphis sub but is was massive in size so I had my installer pull it. I tried an 8" version of the JBL and it sounded good but struggled a tad to push through all the seals and sound dampening Hyundai put in the trunk (very compact though).
My installer was awesome in letting me try all these setups and was pretty on point with telling me that I needed a ported enclosure to get good fill from the trunk and that the box needed to fire to the back of the trunk. He moved it around so I could hear the difference and it was significant.
Quick update on my situation, turns out the installer mistakenly connected to the mid signal instead of the bass so that is why there was so much less bass than I was used to. He corrected it and all is good without have to hassle with anything else.
