Review on 🔇 Enhance Audio Quality with PAC CSS12 Passive Noise Filter - 12 Amp, Choke and Capacitor Design by Leslie Harris

can i give zero stars? Mine may be defective. I use it for noise cancellation on a '96 Cherokee. I have a backup wire from the taillight as a trigger to the SPST relay. Run CSS12 on the bottom of the relay and as soon as I turn on the ignition the whole car dies. I have red for 12V direct from the battery, blue for camera power and black for ground. When I remove it the machine is fine and everything works fine just a few lines on the rear camera. So what the hell?
