Trying to add bass to factory system

[Glen Livet]

I have a 2015 with factory sound system. No subwoofers. I want to keep the factory head unit and audio controls in steering wheel.
I am thinking of adding 2-10” or 3 8” subs into the factory sound system. What’s the best way to add the subs to the factory system?

Audio Control LC2i Pro, and amp/sub combination of your choice. You connect the LC2i to the rear speakers and get power from the amp's power. It will provide a remote turn on signal for the amplier and correct any bass attenuation set by the radio's manufacturer.
