Hello, not long picked up my new 5 series, what a lovely machine. I came from a Golf R. This is so refined and the ride is sublime. Every extra ticked apart from the sound system. Many reviews said to install the Eton sound system. I got the gear, the rears are installed and what a difference. The front can easily be done. But I need tweeter covers. BMW and ebay etc... are near 90 quid plus for 2 plastic covers. Is there anywhere else I can look? I have the actual tweeters, and it worried if these are bare covers or the HK covers etc... I have the foam that is required here. Any help appreciated would be great. Cheers.
