need help for my speakers

Can you please provide some more information on what you mean by "stopped hitting" is there sound coming out of the 6x9s at all. Do they sound blown almost like a rattling sound from the cone portion of the 6x9? or is nothing happening at all? If you have no sound at all they might very well be blown. Do you have a amp hooked up to your highs? Also do you have micro farad caps aka Bass Knockers on all your highs speakers? I would get some of at least 120hz as the lowest frequency they can play. See the picture below. I have 6 of them in my car. One to each speaker including them tweets. Not the exact one but similar.
