I have spent many hours troubleshooting noise and subwoofer level issues in my 2 channel home audio system. I installed two of these (one for each channel due to the spacing between my monoblock amps - you only need one if you're dealing with a stereo amp). As others have pointed out, manufacturing with thin wires etc seems very flimsy, but they work!
