Let’s simplify it by using an everyday example: the humble bicycle. As they say in computer programming, “garbage in, garbage out”. As a result, the noise cancelling circuitry has the wrong reference. The problem is that as the RCA cable runs from the rear of the car to the head unit, the noise changes. Some manufacturers use the amplifier ground as a reference, instead of the head unit. In most vehicles, the amplifier is located in the back of the car.

There are additional problems that pop up when you install an audio signal in a car. This creates noise in the signal after it’s already gone through the noise cancelling circuit. This creates what’s called a “ground loop”, where some voltage flows from the chassis ground to the RCA ground. A cheaply-manufactured amplifier – or one with a defect – might not fully isolate the grounds. First off, the audio cable’s ground needs to be completely isolated from the amplifier’s internal chassis ground. However, there are a few things that can go wrong with this. The difference between the signals is then amplified, which eliminates the noise.Īt least, this is true in theory. The signal is then compared to the signal on the RCA’s shield, which is called a “reference” in electrical jargon. These circuits work by measuring the signal from the RCA cable’s center conductor. Manufacturers have known this for years, and install a noise cancelling circuit on the audio input circuit.

Because stereo systems are full of electronic components, noise is actually inevitable. The first thing you need to understand is that noise is caused by an interference in the electrical signal. But the same principles apply in a home stereo system. So, what causes static when you plug into an aux jack? For our purposes, we’ll be talking primarily about automotive stereo systems.

Which one is the best of the bunch? Let’s take a closer look, and find out. This is a mid-sized device, with a long, 3.3-foot cord. Finally, we’ll check out the Mpow Ground Loop Noise Isolator. This is a very compact device, and sports a 24-inch cord. The next one we’ll look at is the AUKEY Ground Loop Noise Isolator. This is a robust, beefy noise isolator, with a short, 8.5-inch cable. The first option on our list is the BESIGN Ground Loop Noise Isolator. We’ll look at all of their features, and see how they stack up to each other. Today, we’re going to review three of the best ground loop noise isolators on the market. But as with most electronic equipment, not all ground loop noise isolators are not created equal. You can also use them to connect your headphones, or anything that connects via 3.5mm aux.

You can also use them with your home stereo system, to get a better signal on your Bluetooth speaker. Ground loop noise isolators aren’t just for cars, either. Suddenly, all the signal noise is gone, as if by magic.

You plug your Bluetooth aux adapter into it, and plug the isolator into your car’s 3.5mm jack. Depending on your vehicle, you might experience some hissing or static when listening.Ī ground loop noise isolator is one solution to this problem. However, the sound isn’t always good quality. This is way better than the tape decks and CD players we all grew up with. Better yet, you can plug a phone, tablet, or MP3 player into your speakers, or connect via Bluetooth. Thankfully, you don’t have to spend extra money to get a car radio today. Back then, you could get an AM radio added to your car for $130, roughly $1,500 in today’s money. Inspect the serpentine system at 60K miles and replace worn components by 90K miles or as advised by the manufacturer.Car radios have been in existence since 1930. The best way to prevent belt failure is to Be System Smart and think I60 & R90. A squealing belt can be a sign that the belt tensioner is failing and causing belt misalignment. While the belt is off for replacement, give the belt tensioner pulley a spin and listen for bearing noises. A Gates belt wear gauge is included with the purchase of this belt. If you see these, it is time to replace the belt. You should check the serpentine belt at every oil change for cracks and chunks missing out of it and general wear.
