Okay, I'll bite. When I got my NSX, the passanger speaker was starting to go out. When it wasn't working the system sounded like crap. When it was working, it sounded okay. Not great, not bad, but okay. It was something I could live with, but not something I wanted to live with. I ended up with an Alpine 7996 DVD player, an Alpine TME-M760 6.5" LCD in the Honda OEM navigation pod, Diamond Audio S6.0s 6.5" separates in the doors, an Alpine MRV-F450 5 channel amp. My sub is a custom fiberglass enclusure that bolts in the stock sub location with no loss of space. It is not completely installed yet, but currently being installed. I still have some work to do on the fiber glass enclosure. Once I have that done and I know exactly how much volume the enclosure has I will choose the right subwoofer. How does it sound in the NSX? I'm not quite sure yet as I only did a rough test with no real tuning, however, I had similar systems installed in my Acura Legend Coupe and it sounded great. IMHO.
