Panasonic SC PT860 Manuals The above link is the owner's manual - it may help. Here are some other ideas: Try to find out if the crackling sound is coming from all speakers or just one - you may just have one bad speaker. If the crackling happens at high volume settings, you may be overdriving the system - you'll just have to turn it down! Try turning down the bass or the subwoofer level. Is the crackling present with all sources (TV, cable, DVD, bluetooth)?
