Happy Holidays everyone.

I need to replace my blown speakers and I'm thinking of replacing the back speakers as well.
I already have an aftermarket sony radio, aftermarket 4 channel amp and a two channel amp for the sub in the truck.

Currently I can fit 5.25 speakers in the kick panel and 4" in the back.

here is what i like to do and I need your opinon.

For the front im getting Infinity Kappa 50.7cs 2 way.
Not sure whats best, two way or three way

For the back I removed the factory frame and I can fit a 5.25 or a 6.9(might be too much custom work).
Here is where I need the help.
what kind of speakers should I buy for the back?
2 way coaxial or component and any other ideas would be appreciated.

Thanks for your help.

You can buy adapters for the rear to fit 6x9's.
