I have the Genesis G6030 and inorder to turn on all the speakers, you must use one of the DSP settings, like rock, church, pop, hall, or jazz. jall and rock use all the speakers, church pop and jazz use variants of the center, left and right, and the sides. all settings use the subwoofer. the only problem i have with the system is the mute button, intermitantly when i try to unmute the system, it will unmute, and instantly mute again, then flip mute/unmute really fast. i have to pull the remote batteries out to make it stop. then i have to turn the volume all the way up from 00. anyone have this problem?
