Hi All, I have just taken delivery the new MY11 Kluger Grande. I really like the stereo/map interface so I'm not looking to change/upgrade the head unit (other than adding an iPod unit), but the speakers could be better. If I replace just the speakers with better quality 3-way ones, but use the existing the head unit to power them, would I achieve much of a difference or better sound with them? I'm really just looking to get more clarity and volume out of them, not something resembling a full custom car audio installation or sub type set up. Cheers.
