How do you install two 12" subwoofers into a jeep cherokee?

I have completely no experience with car audio but just came across 2 12" kenwood kfc w3012s with a kenwood kac 8105d mono block amp. The deck in my jeep cherokee is a clarion DXZ635MP. i just wanted to know if this setup is possible and if it is, if you could supply directions or a link to a good website that could provide instructions. thanks!
