So I bought this: New Silver HiFi 2 0 Stereo Output Digital Power Amplifier TPA3116 50WX2 | eBay Cheap I know, but I noticed a few things... If there is no audio going thru it, there will be some static/electronic noise coming thru the speakers. Also when playing, I noticed that the audio ( the song being played ) will have a weird alteration to it. Its hard to describe, but Im thinking its something maybe to do with heat? I dont see how though as it runs pretty cool. Maybe this is a common problem on both account above? thanks!
