The advice I have received in the past has been very helpful, so I turn to you guys once again. I have an Onkyo TX-RZ 820, and a Yamaha AS 801. I use the Onkyo AV receiver for movies, and the Yamaha for 2 channel music listening. I have one set of towers connected to the Onkyo, and another set of towers connected to the Yamaha. I have just purchased 2 subs, and I am wondering how I can connect both subs to both amplifiers, and listen to 2 subs when I have the Onkyo on, and listen to 2 subs when I have the Yamaha on. Is this possible? Next issue is about storage. I received another Yamaha AS 801 as a gift, so I put it away after I listened to it only twice. Do I need to be worried if it sits in my closet? I eagerly await some help here. Thanks.
