Stereo in my car sucks...is this one okay?

-I drive a Mitsubishi Lancer, and my current stereo is terrible. My dad pulled me one from a car on his lot (owns a towing company, he has like 54867 cars). It's an Aiwa. It has a CD drive like my old one, but also an MP3 plug-in. I know next to nothing about this particular brand. Any good?no way to know if it is good but the main question is did you get new speakers? that's a big part of any system and probably what you should replace
