I had the same non-ML speakers which were terrible and have replaced the dash and front door speaker. The dash was pretty straight forward but the 8 inch front door speakers required some work due to the way they protrude out. Cutting out some MDF and a good ream of sound deadening material got in sitting nicely with enough room for the window to wind down behind. Overall a vast improvement in the sound quality which is great. For some reason the web page doesn't want to upload the new door speaker images so unable to share that one, but you can see the 8 inch old version here that was taken out
