Hi guys I'm about to buy speakers this week to replace them in my corsa c from 2004 as front speakers start to crack. I would want to get something similar to volkswagen B6 speakers that my dad has. I know they are stock speakers that came with car but not sure how much would I need to spend on speakers to get the same audio quality or better (I have to admit they sound quiet good, although I can hear them failing as at higher volumes base slightly farts?) Any recommendations? I'm going to put some dampening materials to doors as well.
