So when I bought my new car, the rear speakers were blown. Apparently the guy who owned it before me liked loud music but not paying for quality equipment. Anyways, since I'm too poor to actually buy the speakers, amps, etc I'd want right now, I bought some Infinity's off of eBay. And they're all fine except for one, which has a crack running through part of the speaker cone. I know I'll never get it perfect, but I was wondering if there was any way you guys can recommend to fix it up. Maybe some sort of epoxy or silicon glue? Some glue over a tape or fabric backing? I dunno. Any ideas? Any experience? Thanks in advance.
