the celica stereo is not "crap"
If you have a GT, hold down the treble/bass push in button for 15 seconds to "unlock" the midrange control, and the sound will open RIGHT up at 2-4 MID
If you are getting an 03 stereo, be careful of the type you need. Starting in 03, the GT could be bought with the same stereo as the GTS, and will not work in an 00-02 GT. you need to get the basic stereo if you have an 00-02 GT
