this is the second set of PM 4.1s I've had. The first ones lasted 4 days and the amp was to hot to touch and the speakers sounded very staticy. They were replaced and I've had these ones about 7 weeks. About 2 weeks ago I started noticing a slight buzzing or staticy sound coming from the left front channel only on certain songs and only when the volumne is on the low side. Over the last 2 weeks it has started to get worse. You can hear it on more songs and it is slightly more pronounced. I tryed switching the speaker with another and it still shows up in the left front channel. I switched the front channel wires on the back of the amp and now it's in the right front channel so it's specific to the left front channel coming out of the amp. Before I contact Amy about this is there anything else I should try to isolate the problem? Any help would be great Thanks.
