Starting a little project inspired by @JohnnyType2 and his aftermarket sound system -    The sound system in my Scala SEL is actually quite good, delivering a fair amount of punch and body to most music.  However it is not overly crisp or clean in anyway, and above 50% volume starts to distort quite rapidly, and above 60% it full on crackles.  It doesn't have the digital sound package as mentioned by others in Octys and Superbs, and the head unit isn't automatically doing a bass roll-
