There's probably a new thread on this topic every day. Search for speaker upgrade and you'll get a lot of hits.
If you just want speakers and an amp just get what your budget allows. 6.5" will fit in the front and soundbar with plenty of depth in both locations.
With a 2DR wrangler you can fit approximately 10x10" amps under the front seats.
That being said, getting rid of some of the road noise will probably improve the sound you get inside the Jeep more than just tossing in some low end speakers and an amp. It's hard for anything to overcome the 94db of road noise inside a hardtop Rubicon. Up to you though.
But, if I wanted to do things on the cheap and easy, I'd pull the carpets put down a layer of good dampening like second skin and a layer of luxury liner, then put the carpet back in and call it a day. Then look at where I needed to go with the speakers.
