Mine had the Bose subwoofer but no spare wheel.
Now with the Invidia, HFC's, and Takeda intakes, I dont tend to listen to music much any more.
I always had the bass turned right down when it was in, so now I have just turned it back up and its not missed.
I stripped out the 350z on occasion too but never trimmed it back up, just chucked a blanket on the bottom and put everything back once I had finished camping or whatever.
