Speaker problem on rear deck

Hi there,

As of recently I have noticed there is a shaking noise and not a proper sound coming from the rear left speaker on the rear deck so I popped off the cover and took a look

It seems that whenever I push down the cone slightly or hold the wire from two opposite ends (visible in the pic) - the shaking noise stops and sound comes out of the speaker properly.

I am hoping that this could either be repaired easily or covered by hertz warranty -what do you guys think?

Images to pics below - when you open the links right click on the image and open image in new tab as the google drive image viewer is stupid

Thanks!

Your picture shows that the speaker is mounted with only 2 of the 4 holes used.

This is likely the source of the problem - the speaker can vibrate because it's not properly mounted. When you touch the speaker, then you are anchoring the other side, and it doesn't vibrate.

Get a set of mounting rings (adapter for 4-hole to 3-hole) and mount them properly.

I think it has something to do with that metal wire - even if I move it around slightly then the speaker problem goes
