So I have a 98 cherokee sport, it has aftermarket speakers and I just installed a subwoofer not too long ago. When I listen to music that has mid base noise in it, not deep enough for the subwoofer but it is comming from the speakers and I hear a rattle in the front left somewhere, near the control pannel and windshield or where the air vent is near the door. It only happens on the front left side. It gets kind of anoying, I have tried pressing down on the control pannel and around the vents but I still can't figure out what it is.

I don't think I have heard the rattling till a few weeks ago, something may have just began to loosen in it. Because the speakers have been in there for a while.

Maybe someone else could know what is loose or what the problem is.

Thanks
