sorry, i have a pair of focal cv1;s amplified in my front doors. if they are turned up past a medium level, the doors start to shake rattle and roll. and i start to lose quality as the rattling overpowers the tightness of these expensive speakers. Sound deadener? does that cure the shaking? how does it work best?
sound deadedning is definatey the cure you need to get some dynamat or similar and apply as much as you can on your doors. also try putting some where the speaker mounts underneath the speaker around the metal of the door.
