I bought a set of new foam surrounds and put on my rear subs because they were rotted and falling apart. Installed new foam surrounds as per instructions and one speaker is great but the other one has a weird scratchy noise when the cone moves up and down. I assumed I didn't have that one surround centered very well so I removed it and got ready to re do another foam surround on it but I notice the scratchy sound is still there even before I attach the new foam surround. I guess I didn't notice it before I put the first one on. Anyway, I don't see any rips or damage anywhere under the cone or with the spider but it definitely has a scratchy feel and sound when moving the cone. Feels like it is in the very center and base of the spider. Anyone have any experience with these and have any suggestions?
Here is a quick video in which you can hear the scratchy sound.

 

Check to see if the voice coil has a tear, It's underneath the speaker cone.

 

I did the same thing in May. One speaker was not right after the repair. My local stereo guy said the coil was burned out. Ordered a pair of replacements from Amazon, twin coil, minor basket modification to fit a heavier magnet. Works great. I think about $65.

 

Johnny, do you have a link to the ones you bought?

 

Had to remove some rear area in the baskets with a dremel grinding disc. to get them in the basket. Then they slip right in the car. We have the Nav radio and once you take the time to set it up, they sound great. Still rockin with the top down. Amazon link: Pyle PLPW6D 6-Inch 600W Dual 4-Ohm Subwoofer
