hi. I fg'd enclosures for xxx 6.5's in my doors. the driver side is great. the passenger side seems to have a rattling sound during bass. (A while ago, the spider was comming off in about a 1 inch section, but I glued it back on)The other day I pulled the speaker out, checked the spider which is still connected 360 degrees, and cannot find the reason for the rattling/vibration. It sounds like a buzzing rattle, but zippy. any help?!
