Audio help for a beginner?

OP: Getting top-of-the-line components (other than speakers) is a waste in a 370Z (and most other cars) nowadays. Even some of the low-end stuff has good-enough-for-a-small-car specs. No matter what you put in a 370, it's not going to be hi-fi. But then, few people actually like true hi-fi - some like a little more treble and many like more bass. Since you can't get hi-fi (and probably don't want it), why spend the extra bucks for something you won't be able (or want) to hear?

Get some mid-line electronics (features will be more important than audio specs) and some good speakers (speakers/placement will make the most difference in any audio system). Equalize to your taste. Enjoy.
