I have a 92' Mazda Protege, it does what it needs to do, I have no complaints and would have no reason to get a new car, especially because it has good gas mileage. But it has a really bad stereo!! its horrible!! i cant even stand it... I want to get a decent stereo system and speakers, but im scared its gonna get stolen. all the doors lock, but there is no alarm system or anything. but i REAALLY really want a decent stereo in it. what should i do.. thank you so much
