The speaker grills are attached to one big piece that comes off in the center under where your key slot is. You can lift up using both hands and gently pull up on the left and right side on the key slot from underneath. It comes up easily just be gentle. Then the 2 sides of the speaker grills you simply pull forward on the upper corners gently. The whole assembly will then be loose. You can't take it back too far because your tweeters are still plugged in so be careful how far back you pull it. You won't need to unhook the tweeters to just get the grills cleaned off, there is plenty of room to get your hand in there. It will keep happening however......
