2012 CVO speaker problem

[Street Glide]

My 2012 Street Glide CVO has a total of 8 speakers, the rear right side saddle bag speaker gives off a high pitch crackling sound, the rest of the speakers are fine.

    Question, do you think the speaker is faulty or could it be the wiring to the speaker is shorting out?

    Thanks in Advance.

May be the amp.
Swap the rear output from left to right and see if the defect follows the output or stays with the speaker
