[quote=paramount]I wouldn’t consider a car an ideal medium for audiophiles at all.

At any rate, the BMW HiFi system sounds great, even at high db levels.

The Green Manalishi (With the Two Prong Crown) sounds absolutely awesome.

Sonic quality is exceptional in my 328i, which in a high end car one would expect.[/quote]
You’re right, it’s not ideal, but you have to work with what you have. I always bring my Eagle’s CD to demo stereo. Hotel California is one of the best song to test the capability of the stereo. A lot of the 30k+ cars’ stereo does decent, but the highs are not as crisp as I would like and the lows are definitely not as deep and tight. The beginning drum part really test the lows and the guitar solo really test the mids and highs. If you can close your eyes and hear every string being pluck and it sounds as if the guitar is right next to you, then we’re getting some where. Somehow, I doubt a 8″ sub can reproduce notes below 80Hz well like a 10″ or 12″ sub can. When those low notes hit, with a good system, you’ll feel it in your chest, not just hear it. I haven’t seen any stock system that can do that, BMW include. I haven’t tried the latest one, so maybe they’ve improved, but somehow, I doubt it.
