I bought S10 few years ago, and it worked fined for about one year.  Then all of a sudden, the sound started to fade in and out.  I still have a green light, but the S10 produces no sound. I switched subwoofer (another mirage sub) and it worked so I know it's not the receiver or the cable.   I am in the process of builiding a Home Theatre so I put this issue on hold.  What do I need to do here? 

 In addition, how can I use two subwoofers in my home theatre.  How do I wire them?  Thanks.

I bought Mirage S10 in 2005, but actually used it for about 1 year.  My amp is out according to MIRAGE.  Depending on the cost, I am going with HSU or SVS Subwoofer!  No more MIRAGE for me.
