upgrading the factory sounds

[acrbill]

Any advice on how I can upgrade the sound of the stock radio? I really don't like aftermarket radios but the factory stuff just doesn't sound great. Without adding sub or super expensive speakers what can I do?

When I installed my power locks I noticed that the door speakers where junk. They barely weighed anything since the magnet so so small.

If I upgrade the speakers should I upgrade the wiring? I don't want to add a ton of weight to the car either.

what size speakers? Are they all 6.5"? On crutchfield they have "component systems" that come with little tweeter looking speakers. Is that something I should look into? Or should I just replace what I currently have?
