this has happened since i hooked up the new headunit. its in a2008 nissan maxima with bose. does it on heavy bass songs more with my ipod and cd/dvd then anything else. seems to happen at higher volumes and it seems to happen when its on neutral with balance and fade. now it goes away if i fade it to the rear more . and i also have replaced the factory speakers with new ones. going to replace bose amp.
