The reason?
The IS300 has one of the best stock stereos on the market, I'd say one of the best I've ever heard. It's better than the one my mother has in her LS400.
It might not be powerfull enough to wake the neighbors or rattle your teeth, but before you "plan" on changing anything, take a good long listen to it... u might be surprised.

- 2 tweeters, by side mirrors. (I think 1")
- 2 6.5" in front doors
- 2 2-way (they consider it to be "4 speakers") 6x9"
