JL audio a4300 hookup

My friend just aquired 2 kicker comp 10s(Not my favorite) along with the JL amp mentioned in title. I dont have any experience hooking up 2 subs to a 4 channel. He is wanting me to wire it up for him. Saw that it gives 220w at 4 ohms x2. Just wondering how i would go about wiring this thing up for him. Probably gonna go with 6 ga power/ground and 16/14(Idk which would be better)prolly 14. He isnt looking to ball out just get some bump going. He got the setup for 100 with a radio so im just trying to help a brother out. Any info would be great thank you all

Also the car is a 2015 Hyundai accent if that helps. Think the headunit puts out @ 4 ohm
