🚗 12V Car EMI Noise Ground Loop Isolator Power Filter for Auto Stereo Audio Radios Amplifiers Speakers Equalizers Subwoofers Review

After adding a secondary stereo from the speakers, the engine began to make a lot of noise. It worked, there was no more engine noise in my speakers.

This product was added to my stereo due to static electricity being generated when the off-road lights are turned on. This is a decent looking item. Doesn't really help and doesn't do anything.

Just what you need without sacrificing sound quality. Tons of people say it doesn't work. This worked fine for me. If it doesn't work, it most likely means there is a bad ground somewhere in your power system. That's a fair price for the end result.

It successfully filtered out 100Hz noise on my 12V power rail. The build quality is pretty rough and they only use a 16V nominal capacitor. Quite disappointing because I'd order more of these if they were rated at 35V. The board isn't even connected to the chassis so it just hangs there with the component leads rubbing against an insulator glued to the bottom of the metal case .

Some of these mufflers are rubbish but not this one! For the price the quality is great and I laughed at the sheer amount of extra insulation around the wires. Turns off all sounds on my '88 Lincoln. On older vehicles, this annoying noise is more likely to occur due to the simplicity of the ignition system and the discharge of high voltage from the ignition coil. This small detail completely removes the damaged sound from the radio/stereo.

I have very few negative reviews compared to the amount of positive ones. However, the thing doesn't work. I didn't get any noise reduction upon installation. I can see where some have had decent results. That may mean I just got a bad block. The build quality isn't that great when I looked inside. Wire gauge is also deceptive. It looks like an 8 gauge in the photo, but it's actually closer to a 14 gauge. Current carrying capacity is limited. I would choose something else or order parts and…
