First did you switch the amps and did the static go to the other speaker?? If so, it is in the amp, if not... keep switching IC and PC, if it never switches, call the electrician.
Drtmth58, as for rage I must differ, I have found as each new cordless phone comes out touting better range the range actually diminishes. My older 900 mHz phone would work fine on the beach from my condo, when I 'upgraded' to a 2.4 GHz, it no longer worked on the beach. When I bought my house (sorry to lose the beachfront but..) I got a 5.8GHz phone, damn thing doesn't work in the driveway!!!
