I have a 2000 ford mustang and the stereo inside it is just awful. There's still a cassette and when i have the cassete-ipod adapter in, half of the time it doesn't work. I am starting to save up for a new sound sytem and i want it to have a good bass and be loud. Any suggestions on good brands, certain types, and where to find them? (I'm not worried about prices yet) Thanks so much!
