I have a yamaha RX-V663 receiver. i would like to set up two speakers in the bathroom so that the girlfriend or i can listen to music in the shower. i dont know if i should have the settings on zone2, front b, or zone b. however, when i set it to front b, zone b, or presence, it says that its not available. the two speakers are connected and they are just small surround speakers. when i set it to zone2, it is available but i cannot get it to play. should i have front tower speakers or am i missing something else. thanks in advance for the help.
