The basic system sound is (to be frank) rubbish.
The soundpack is (to be honest) adequate.
The soundpack could be made better by putting in component aftermarket speakers up front and in the rear. The bass isn't bad, but it isn't "beefy" enough.
At higher volumes both systems degrade quickly with too much "noise".
If you haven't heard something like the Harmon Kardon in the BMW, or Bose in the Audi or a fairly cheap decent aftermarket install, then you would be happy with the Soundpack.
For comparison - the wife has a 1.2 punto :embarassed: which has a better sound system in it from the factory than the basic system in the VW and sounds as good as the soundpack set up.
