Inquiry (采购产品): speaker slots hello, i just bought 2 sets of new speakers for my car, one set of speakers is 6"x9" and the other is 4"x10", but if i installed the speakers right now the metal that my doors are made out of would send off annoying vibrations whenever i turn my volume up too loud, i was wondering if i should get completely new doors or if i could just get better, more solid metal that is firmer and isn't going to vibrate, welded onto my doors. if your company could help me out please e-mail me back **** Hidden Message ***** ryan jelinek 1235 tucker hill rd weaverville, CA 96093 USA Company: none Phone: 530-623-5192 E-mail: tighty_whitey_man@hotmail.com **** Hidden Message ***** tighty_whitey_man@hotmail.com
