I just got the logitech 5.1 Z640 speakers. They are great, love them...BUT...the sub makes a hissing. It doesnt have to be on, or music playing, it just has to have power; be plugged in. Any suggestions?
i have the same speakers sounds like a bad connection in one of the wires. wiggle the connectors to see if one is going bad or posibly something in side on the amp is going bad. if they are still under warranty i would call and get it repalces luckly i havent had any problems with mine also check for any thing near that might cause an interference
Open the speakers and check for snakes ! Be carefull not to get bit or strangled ! I am not responsible for your death !
