Hey, just wondering if anyone sells head units here? I own a 90 integra, and its stock head unit/speakers are *cough*... I dont want an awesome unit head unit or anything, just something decent... Also I want to get sum 6x9's, but my mate who is into stereo said if I want to get some 6x9's in my car and then I got a sub it could distort n stuff, is that true?
