I honestly don't see how anything besides a defect or over excursion would cause something like this. Amps shouldn't matter.

Just making an observation. If the only two subwoofers that are showing these marks are connected to one amp and the other two are fine connected to the other amp, I am just making the connection. With that said if one amp's gain is set too high it could definitely cause the over-excursion that is probably the root of the problem. Fix the cause, the problem disappears.

On another note, is the box a common chamber or are they separate?

Get a wet towel and wipe that bish, to me that looks like it's just dirty or is rubbing against something.
