Ticking noise from speaker

Hey all, just made a 13hr trip to go back to work, and on the road trip there i noticed a ticking, finally pinpointed it to the passenger left dash speaker. It seems to the tick is directly correlated to tire speed, slow tick when going slow, almost like a rock in the tire, and fast when I accelerate. When I turn off the radio it goes away. This issue just happened on this road trip, I have no idea what it could be, I have an aftermarket radio but I've the truck almost a year now and this just happened. Wondering if it could be a blown speaker or a wire is grounding out. Any help or ideas are appreciated

 

I had this in my 38 Oldsmobile. It’s linked to the “spark” in your electrical system and an aftermarket radio. Try a filter if they still sell such things. On my vehicle it only softened the tick

 

Sounds like a grounding issue to me

 

It doesn't do it when the truck is stopped, in any gear, even when I rev the engine

 

I unplugged the speaker in question so ill see if that fixes it, if it does ill trace down the short
