Hello I have a panasonic radio, and the front 2 speakers at the doors I have to walk over the radio and the rear 2 and the sub over an amplifier. now the question if I want to change the balance, and I turn over to the right only the rear 2 speakers and front the left speaker, and if I turn the balance to the left only the sub and front the left speaker must do so? and if I change the fade then happens garnix
