Pffffffft 6 stacker, wow.. I reckon I could fit more songs on an mp3 cd then you could fit on your 6 discs. I have premo sound and theres nothing premo about it. If its so premo then why upgrade it?? For the price of a GOOD line level converter you could get a GOOD headunit, without the fuss... Then again its up to you, I also went through the 'I want it to look stock' phase, then my wonderful 6 stacker decided to sh*t itself, so I went out and bought myself an Alpine deck, to connect to the rest of my gear, and its gonna be DOOF DOOF all the way. My 2c.
