Subwoofer with stock amp?

Hello!
I have a Pontiac Vibe 09 w/o moonson system. I was wanting to add a subwoofer to my current audio system in the car.
It still has the stock HU installed as I don't want to get rid of the on-star system. There is a stock amplifier underneath the driver's
seat. Is there anyway I could hook this up:

Or do I have to replace the current HU?
Or can I keep my stock HU and install a new amp?

Thanks!
