Well i have just fitted the new back boxes and i must admit i was worred that it would sound to loud with the GRUPPE M aswell.
I am so pleased to say that it sounds fantastic and also when at cruising speed there is no droning.
Really really pleased and the finish is fantastic. Def worth the money and i personnaly think looks great too.
I took a photo of one side fitted to show the difference.
