Hello - <BR>I have a 2.4T with Premium Package. This has the HU-613 Radio package, 8 speakers. I do not care for the sound. I have read much of the information, and it appears that I can upgrade to the Volvo 200 Watt AMP, and this should improve the sound significantly. Has anyone had success with this? Do I need to upgrade the speakers as well (I hope not!).<BR>Any help and information is greatly appreciated.
