what sizes are all the factory speakers in a 2.3?

 

umm 6x9 in the back, and im pretty sure 6.5 in the front, and also i think theyre are tweeters above the dash, but i may be wrong, they are in the corner

 

Yeah, It's 6x9's on the rear deck, 6 1/2's in the door, and tweets in the dash. You could just get a 6 1/2 component set.

 

I went with a 6.5" Component set with matched silk tweeters and 6x9's for the back, just watch the mounting depths for the 6x9's mine were WAY too big for my back deck. I tried all kinda spacers, and ended up having to make custom spacers out of mdf. Here's a little write-up on what I did so far. Have to use spacers for my 6.5" too
