1998 A4 Bose Tweeter rattling
 

Hello, The left front tweeter in my 1998.5 A4, with the Bose system, is rattleing badly so I think that it is probably blown. Overall I like the sounds sytem and would like to spend as little as possible to fix the problem. What should I replace it with? 1 new Bose/Audi tweeter, replace both tweeters, replace tweeters with aftermarket? If I do go down the aftermarket road what specs to I have to look for? thank you for your advice.

The tweeters aren't Bose they're just the standard Nokia tweeters
 

They are 1" units and you can replace them with anything, the spec is so feeble anything aftermarket will be superior. Just ensure they have an inline capacitor rather than needing a proper crossover.
