Well it's weird because it's only the passenger side that keeps doing it. That's why I was thinking maybe it had something to do with the sub since it's installed on that side. I'm taking it back on Saturday and they're going to take everything apart and try to figure it out.
They thought it might have something to do when the tapped into the oem system to get a channel for the amp that something is getting distorted to that speaker. I admittedly know really nothing about the stereo/wiring stuff so I'm trusting them to figure it out. The speaker is definitely blown, sounds just like it did when it happened to the other one. I have everything faded to the front for now because it sounds horrible otherwise.
