Review on 🔊 Enhance Audio Quality with Universal 10 Amp Inline Power Noise Suppressor Filter Eliminator Isolator by Jose Morrison

This filter worked great with my Jeep CB radio. I was able to make a detachable track harness to also provide the GMRS radio which I installed at the same time. The CB suffered from some ignition noise - quite annoying - but the ANL switch on the radio brought it down to an acceptable level. However, once I add this filter, the ignition noise is completely GONE, even with ANL off! probably has no condition. I connected RED to +12 volts and BLUE powers the radio. BLACK of course goes to practical ground and should be grounded directly to the chassis using as short a wire as possible - I actually used a braid to connect the ground.
