How to add two subwoofer's to factory G37 Coupe radio

[Drizzydrake1]

I'm kind of new to car audio so I was just wondering what connections or converters I would need to install two Rockford P2's in my car as I already have the subs, box and amp. I have a stock Bose system in the car, which is an 08 Infiniti G37 Coupe...if you could give specific brands or even links to products that would be much appreciated.

You can use a decent loc(line output convetor)and use the rear woofer signal to the loc. I didnt touch my g37 to much hassel..
