Incar Audio Systems

Ok, I have a 1987 Porche 924S and am looking to improve the sound system. I don’t want to spend too much and am not looking into getting anything to extravagant. What I want is to improve the sound quality at the level it’s already at as well as give me the ability to crank up the sound without fear of braking anything. I was thinking of a couple of tweeters, woofers and probably a 10′ sub, but I’m not sure on anything from brand to size and would atleast like to have an idea of what I’m looking for before getting jipped at any audio stores.
