Hello Since I don’t like the sound of the original speakers I would like to install new speakers. I already read a lot about insulation but at the moment the money is missing. So I’m just looking for new speakers for front and it shouldn’t require too many conversion measures. Budget is about 70€ (but can also post “P/L scratcher” up to 100€ if you think it’s worth it) So radio I own a Kenwood KDC-164UR. To the car : Skoda Octavia 2002 Facelift
