Sounds to me based off your description that the speakers are blown. Particularly if they get that sound at lower volume levels, meaning as soon as you roll into the volume (about halfway to loud in simplest terms).
I'd do speaker replacement, and sound deadening "while you are in there". Sounds like you already know the benefits of the deadening!
