Installation for 500€ what is recommended

Hello together, after I separate myself from my current Golf IV and therefore also from my system (was free but I knew that I would have got much better components for the money if I had inquired before but no matter what I do better this time) So my next car will be a C-Class and I would spend about 500€ on boxes v/h, end socket etc (must not be so much can also cost less). Irm and Navi want to have that of course can also cost more (max 1500€). Please make suggestions what you would recommend I actually hear almost everything (Pop,Hipp Hopp, House etc) preferably with lots of bass greetings Thorsten
