Premium sound sounds like shit

I'll probably sell this head unit, buy 4 new coaxials and let that be it. I don't need much bass, but this all treble sounds like complete shit..

I have a full stock system for sale.

So I just bought a 89 325is with premium sound and it sounds like complete shit. My old e just had stock sound and the quality was 100% better. I have some JVC head unit which actually isn't bad, but the speakers can't handle shit. My old car had a pioneer something and 2 coaxial pioneers in the rear. I thought preium would sound better, lol...
