AUX cable quality.playing music from my iPhone in the car?

I currently have an AUX cable that I bought for $2.It's made in China, and it's probably not the best AUX cable you can find. I use it in my BMW, and the music doesn't really sound that great. My question is whether a cable of better quality can make the music sound better or whether the problem is within the BMW's system.
