"Supposed to sound" sounds like you were live in the room when they recorded it. Sounds like you're in the cottage, in the attic. Yes, the car can mold the sound, but that's the idea of SQL, to compensate for that and get it to sound as close to original master as possible.
As I said, quality is proper tuning of EQs, amps, crossovers, etc. for proper audio imaging. Not just "How much wattage can I cram into my Suburban?" Just because you can set off car alarms with your system doesn't make you an audiophile.
What do you mean it's not a live performace? Were they dead when they recorded it? It was live in the studio. No, it's not a live concert recording.
I don't know why it's so hard to accept that there's a such thing as sound quality when it comes to car audio.
I have plenty of vinyl, thanks. And I've even had turntables set up in my van and connected to my stereo, so I guess I had the highest-fidelity system possible, hm? (hardly)
