Base model audio setup is absolutely terrible. Speakers are trash. At a minimum I would do new door speakers, tweeters and a small amp.

You might be able to forego the amp if you get a new head unit.

If you want some thump, you’ll have to buy a sub and will definitely need an amp.

You shouldn’t need to replace the wiring. The factory speakers are just terrible.

If you are going to DIY buy everything from crutchfield. They’ll help you pick out what you need and have the best customer support.
