I have a 10' powered JBL sub and a Yamaha RX-V663 receiver, the reveiver shows that there is an LFE out but the sub does not turn on automatically. If I unplug the rca jack and plug it back into the sub everything if fine until I turn everything off and the sub goes back into standby, I have to repeat the same process over again to get it to work again. Is the problem the sub or the amp? Any help is appreciated!
