Recently purchased a 2010 LX570 and used all the valuable insights here to help guide my decision. Now I'll try to pay it back/forward by contributing when appropriate. My first order of biz is to replace the blown rear subwoofer without "investing" $600-800+ for the whole assembly (new). I've spent several hours on here and elsewhere trying to determine the best course and not sure yet what I'll do. Here's wishing y'all a Happy and Prosperous New Year full of laughter and joy?
