Two 12s is alot of bass for an old guy! I have no idea what that truck takes for speakers, but I put Polk DB651s in my doors on my Duramax. Good sound for the money, I believe they were $60 a pair and they are marine grade. I have an 8" JL sub with their amp and the sound is awesome for that small of a sub. Wont shake your doors off, but just a really "full" sound that you can feel when you turn it up.
Like said above I would go through crutchfield, their site is super easy to use and tells you what will and wont fit, plus they have great customer service. Lots of good review as well. Powered woofers are nice for trucks, they save alot of space.
Every single person is gonna recommend something different so I would find something with really good reviews in the sizes you want and pull the trigger. I dont think you can go wrong that way.
