Whenever I turn up my volume my speakers sound muffled and are rattling as well as the sound not being as clear or loud as it should be. What could be the cause of this?
If the sound is muffled and/or producing a 'rattling noise', this could be result of speakers that need to be replaced. Replacement speakers can be purchased here.
