have this new Rw-10D ,, the entire system was installed by a dealer,, the RW-10D keeps cutting out. I called the dealer and they think it may be a connection, well that was checked and it did the same thing with a new cable. I use a Sony STR-500 A/V reciever and have the input run to the L input on the subwoofer, although it does the cutting out whether it is in the L or the R input on the subwoofer. Electrical is checked, no problems there, the display and all works when it is not putting out sound. What could be causing this, the dealer says if this is a bad subwoofer from Klipsch it will be the first they have ever seen. Is there something i am not trying?
