It really depends how much work you want to do and how much money you want to spend.
The Sony has an amp under the console for all the speakers. Do you more power, clearer sound or what?
I would start out by replacing the factory speakers and the sub first. Then move to the next step if you aren't happy.
The next step would be new amps.
