Take a 1.5 -volt battery (AA, C, or D) and using a small gauge wire, attach the positive terminal of the battery to the positive terminal of the speaker, and then attach a wire to the negative terminal of the battery and then tap the wire to the negative terminal of the speaker. Each tap should push the cone out and you'll hear it make a soft pop sound. Reversing the wires during this test will pull the cone in and give you the same pop sound. Don't use a 9-volt battery during this test or you could damage the speaker. If the speaker makes the pop noise, there's probably nothing wrong with it.
However, you mention replacing a harness. Can you elaborate on replacing this harness?
My guess is something to do with the harness change is the cause of the problem.

Actually did tap the cone while it was all apart and seemed fine, but the harness I meant was a schroth racing harness so nothing to do with the speakers other than needing to pull a bunch of panels around that speaker to install it.
