    Hard to find unless online.

    This Noise Suppressor works. If you do not know how it works, because it lacks instructions, you may have to experiment to resolve your interference issue. Before the amp or after the receiver head, mmm that's the question. I installed this product in a 1978 Chevy Corvette with the main problem with engine noise. Let's see, 1978? The year of the Cat?

    Serves its Purpose.

    I purchased two of these filters (one for front, one for rear) after getting an annoying squeal that fluctuated with acceleration input through my Kenwood receiver. I noticed this was primarily coming out of my left-rear speaker. After installing these filters, the squeal has been reduced to barely noticeable levels (albeit not entirely eliminated). Installation was a breeze, as I simply unplugged my RCA cables from the factory amp into the radio and plugged the filter to run in series between the radio and the cables (it is even simpler than it sounds). For my installation, I didn't need to hook up the brown ground wires, it just worsened things if they were connected. Overall, good product and I recommend them if you are experiencing similar issues.

    Fixed feedback buzz in PC to Stereo Connection

    Great little device. before tearing your computer down to see where it's not grounded properly (because it probably is) do s simple check. Are your Stereo and your PC on the same power circuit? If yes you might get that annoying 50Hz to 60Hz buzz from your speakers. This fixes the issue because it was designed to do so. It isolates and traps the ground loop feedback and - magically - no more buzz. It's a 2 minute fix that the stereo folks have know about for decades (because it's an analog issue not a digital one). If you have it though the audio inputs it's easy. They make ones for 1/8in plugs as well but this one fit my need perfectly.
