Headunit Replacement??
 

Hi Everyone,

I have a 2004 Madza 3 GT Sedan. 6800KM on it. Has anyone heard of any problems replacing the stock headunit with an after market one??

In addition, what size of speaker sare in the doors? No information is the owner's manual. I would like some boston acoustic high for new front speaker not sure what would fit?

Thanks :bt:
