    It WORKS!

    Posted by Patrick Marshall on Jan 11, 2026

    I tried 3 other brands before trying this one, none of them worked. This filter did not reduce the noise 100% but greatly reduced it. Nobody thinks of the looks except D4S, it will be visible so looks really matter to me. This matches my JP amps and my DSP. I only put it on 1 or my 3 rca's. I just bought 2 more. Great product as always. Highly recommend

    I was amazed by the clarity this little noise filter provides. Super clean signal out of the filter. Great product!
