Can i hook up my subwoofers with this radio?

I have a 2011 scion tc, an enclosed box with 2-12in jl audio w-1s, 1200 watt visonik amp , the radio that came with the car was a scion navigation system 200. I went to a car/audio place and they are trying to charge me like 100 bucks for installation if my radion doesnt have some sort of port in the back. If anyone knows if this radio is compatible let me know because i hate getting ripped off by those guys who dont think i know anything about audio
