my plan is to don't have many plans for the car. But one thing I will do in the beginning of the year is to change the factory speakers with aftermarkets one(after I changed my radio for an aftermarket I really discovered how bad the speakers are. Haven't decided on brand yet but have some in mind. Don't think I'll buy an amp, hopefully just changing speakers would make me happy. doesn't after extreme sound. Just something it's not irritating to listen at.
