The stock speakers in the non Bose system are terrible. The best bang for the buck is swapping those out. I added Infinity Reference to the doors and Kenwood Excelon to the dash, nothing fancy the whole set was under $300 on Crutchfield. I’ve also added the kicker sub and amp, it does make everything sound a bit better and add quite a bit at the low end. I don’t know if I’d buy the kicker kit if I installed the speakers before ordering. Start with speakers, then look at the kicker kit if you want to limit modifications to the truck.
