These are the speaker sizes for the SC400. The little upper grills are the tweeters. They're about 1" each. You might use a flat head screw driver to un-snap it and check for size. The front speakers are slightly smaller than 4". The rear speakers are 4.25". The sub is 10".

However, you can always upgrade to larger sizes by using the MDF wood templates for the front and rear. For the front, I checked before and there're no 4" aftermarket speakers that are as good and powerful as the stock speakers. Don't waste your money to replace the same size. You can go to 5.25" with template or keep the stock ones. I wasted my $$ for the same size on the front and decided to keep the stock ones. The stock ones have really huge magnets for their tiny size. For the rear, many people have succesfully replaced with 6.5" and 5.25" with templates. An aftermarket 10" sub might not fit perfectly in the stock location without some minor modifications.
