I have to agree that the only way for decent sounds is to go aftermarket.
The OEM iPOD dock is a waste of time and money.
The OEM speakers can all be bought for less than £50, so imagine how cheap and nasty they are to actually make

The OEM head units specifically have VW sound processing to reduce the sound at certain volumes and frequencies as they know the stock speakers can't handle them
This is why an aftermarket head unit will sound better until the volume is wound up.
Even cheap aftermarket speakers are leagues better than the MKV OEM speakers.
The MKVI dynaudio system speakers are much better, but would cost you more than a decent aftermarket set-up.
