One question to the experienced audio experts: I would like to bring some sound to my A4 B5. It doesn’t have to blow your ears out, but it should be enough for everyday life. Best for the original sizes: 13cm compo for front and 16.5cm coax for back. Also, of course, a suitable amplifier. For everything together I would have a budget of roundabout 500€. Since I am relatively new in the audio area and my internet searches have only turned out nonsense I ask here for some Hil Thank you in advance
