I have a 55 plate Mk 5 Golf GTi with what I assume is the standard sound system. Compared to my previous Mk 4 Golf 1.6 SE i have been really disappointed with the sound quality of the CD/radio. Is this something others are familiar with? Can anyone suggest a cost-effective way to improve it, please? I'm not an expert so not even sure if the issue related to the stereo or the speakers??? Any suggestions most welcome! Thanks. Robbie
