Well our car is now 6 years old. I think that my husband has finally blown one of the speakers in it. I can hear a ratling when I turn the radio up a little bit. I have no idea how he was able to do that by playing country music...I guess I will have to go out and get a new set of marine speakers because that rattling noise is really going to drive me insane to have to listen to daily. I can see blowing a speaker playing my music but come on...country?
