6x9 is the quick fix, you can then look to door the door speakers. But if you really want to improve it a amp bypass and components are needed. Fair bit of work and no guarantee you won't induce engine whine.
The premium have rear door speakers that's the difference. I bypassed the whole amp, stuck comps in the doors and tweeters in stock location and sub in the back. Depending on needs rear parcel and front door speakers with coaxial speakers would be ok imo? But I've not heard this setup myself
