I must be a dog (nobody can hear the buzz)

Help me please I think I’m a dog..... I was looking but couldn’t find anything. I have a 15 limited cm trd with jbl facrory no mods and I hear the rpms or buzz of motor though the passenger side speakers have taken it back to the dealer multiple time but they say that they “can’t duplicate” it so nothing is wrong. Driving me nuts. I don’t really want to replace the system that’s way I got the up grade but kinda disappointed in sound of the jbl’s...

 

Mine was doing it and it turned out to be a blown speaker.

Mine was the center dash

This was a brand new install though and JL speakers.

 

Blower motor?

 

Typically when you get a noise like that, it's a loose or bad ground. Good luck

 

Do you hear it when playing from all sources or just from a certain one? I had a similar issue when charging my phone and listening through the AUX port. If it is constant regardless of source I would begin by disconnecting the speaker in the door and see if it goes away. If it does, try a different speaker at that location, if the noise goes away you know it is the speaker, if it is present with both the original and a new speaker it could be a damaged wire going to that speaker. As others have said that noise is often a bad/loose ground.
