I have an E30, and I had to replace the head unit just so I could listen to CD's, and the amp in the car blows so much. It can barely go loud at all, then it sounds like my speakers are popping, when really, the speakers are fine, the amp just sucks so much. AND I get this loud and high frequency like radio sound contantly, and it goes louder when I give it more gas and get higher RPMs, so if you get a new head set, you gotta get this ignition stuff to take out this weird sound, and its such a bitch to replace head sets in BMW's. There is so much wireshit you have to do..took us many hours...and there are like duplicate wires for each speaker. its complicated and a neusence.
