A couple of things to check..
Are the subwoofer and AVR connected to the same
AC outlet circuit?
If YES, then the subwoofer when a heavy bass signal hits may be drawing down the AC line voltage. If the AC voltage to the AVR sags enough
just for a split second, then the AVR may go into Stand-By. This also could happen if the house has older electrical wiring, with lower current capability. Additionally if some other applinace or component is connected to the same AC line circuit this may cause the voltage to sag as well.
Just my $0.01..
