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

available I have a Pioneer W4660NEX head unit in my Porsche Cayman. Everything I did for this device and the previous Pumpkin Android device resulted in a strong generator hum. I've been working on this off and on for two years! I spent $600 on a new main unit to have it repaired. I've tried rare magnets, extra ground wires, rewiring, rerouting power and ground from speakers, swapping RCA connectors, and isolating it all. No dice. I cut the red + power wire on the radio side ISO harness. Place the red line to the car and the blue line to the radio. The black one was screwed to an obvious ground point on the Pioneer head unit case near the fan. Howling noise has been completely eliminated. No qualms about this generator hum elimination product.
