I've heard there is a 1200w upgrade harmon system which was an option, my speakers say harmon on them but not sure what else i can check to see what option if any i have or whether i have the basic speaker system? any help will be great I've googled with not much luck

The upgraded system says HD in the Harman Kardon badge and the square around the bottom speaker in the front door has a silver border.

If you think yours sounds rubbish, turn the logic 7 bit off.... Made a world of difference to mine.

I now have some volume!
