Touring speaker size?
 

Does anyone know what size speaker fit on the dash? It look very small but i can't firgure out it.

If you are looking to replace it, you can either get ripped off by mazda, see if someone has a used one, or buy a set of tweeters and keep one as a spare. The speaker is about 1 7/8 inch. The only aftermarket replacement would be a tweeter .
