Hey everyone I just got a Mazda3 as a graduation present but the stock speakers suck! Anyone able to confirm the front speaker size of a 2010 Mazda3 GX non boss version. Ive been to a couple sites and they all give me different sizes. I need to know the exact size, friend can get me a deal on new speakers but there will be no returns.

Thanks

pull the door panel off and pop a speaker out so you can measure for the largest replacement you can fit. I can say 5x7" but different manufacturers have some different hole, height, depth measurements. This has a plastic mounting ring too, so that effects the dimentions too.
remember to put the window down to see what clearance you have to work with.
