I'm thinking about buying new speaker's for my C230K and I was wondering what is the best brand to by for a MB instead of BOISE. If possible can you guys post some links to the sites were some speakers are avaliable. What are the size and dimesions i should buy.

 

You can't go wrong with ADS or MB Quart car audio products (very high end products available either). As for sizes, call any dealer as they should have installation data including replacement speaker sizes. Hope this helps.
