You may be talking about phreddy's upgrade prehaps?
It allows you to hook up amplifiers using rca's.
Berlina and calais are six stacker systems but it uses the same upgrade as the single disc as far as i know.
See this thread here for more info
in the calais, statesman, caprice, and hsv models they had what was called the premium system which just had a subwoofer and amp and more power output than stock, it was an option on all other models too
