Stock stereo replacing with Infinity head
 

So I have on 09' JK with the stock head unit (non-infinity). Living in Utah, everyone is pimpin out their city slicker jeeps and I have found some great deals on the infinity head unit, amp and sub from sahara and rubi models. Was wondering if I could do a clean swap to replace the stock head unit I have now. Not looking to spend a lot of money and figured this would be a good upgrade for cheap. Will this work? Kind of a newb when it comes to stereo upgrades and wiring. Will it be much more work than i am thinking? Any thoughts help
