Why Car Speakers Cut Out At Low Volume?

Imagine you’re driving your car and enjoying your music and suddenly your speakers cut out at low volume. It can be incredibly frustrating at that moment. Car speakers tend to wear out, and even break, over time. This is especially true with the kind of lower-quality original equipment (OE) speakers that most cars and trucks come equipped with. Internal components wear out or come loose through regular use.

If you’ve come looking out for the reasons and solutions to this issue then, there is no need to panic, you’re at the right place! In this article, we’ll discuss some common causes of speaker cuts off in between.

What Are The Causes Of Car Speakers Cut Out At Low Volume?

There are a few common reasons why your car speakers might be cutting out. Below are some of the most likely culprits:

1. Wiring Issue:-

A common problem that can cause speakers to cut out randomly is a wiring issue. Wires can become loose or corroded, which can disrupt the sound signal. If it’s an issue with the power cable, the speaker and the head unit will turn off and on simultaneously.

2. Defective Amplifier:-

A defective amplifier can also cause problems with the sound signal and lead to speaker cuts. If the amplifier is not sending enough power to the speakers and will lead the speakers cut out at low volume. If you suspect that your amplifier might be at fault, you can test it by bypassing it completely.

3. Defective Speaker:-

If the speaker still cuts out when the amplifier is bypassed, then it’s likely that the problem is with the speakers and you’ll need to replace it. A defective speaker can also cause problems with the sound signal. If one of your car speakers isn’t working properly, it could disrupt the sound signal and lead to pops and cutting out.

How To Know Whether The Car Speakers Are Blown Out?

It’s pretty easy to tell when car speakers blow out if you’re there when it happens because you’ll immediately notice that they stop working or no longer sound normal. If it happens when you’re not around, and the guilty party isn’t willing to fess up, verifying blown speakers takes a little work.

The surest way to test the speakers is to disconnect the speaker and check for continuity. If there isn’t any continuity between the speaker terminals, that usually means it’s blown.

How To Fix The Issue Of Defective Car Speakers?

If you’re experiencing car speakers cut out at low volume, there are a few things you can do to try and fix the problem:

Step 1:- Check The Ground Connection

A loose ground connection is one of the most common causes of speaker problems. If the ground wire is not properly connected, it can cause all sorts of sound issues. To check the ground connection, first, get a voltmeter that can read ohm. Then, connect one probe to the negative battery terminal and the other probe to the ground connection of the component.

If the reading is below 5 ohms, the ground is good to go. If that’s not the case, make sure the ground wire is properly connected to a bare metal surface of the car.

Step 2:- Remove Interference

If you’re using an aftermarket radio, it’s possible that the problem is caused by interference from the engine. To fix this, you can try to reroute the power and ground wires away from engine components. You can also use shielded RCA cables to reduce interference.

Step 3:- Connect Loose Wires

To fix this issue, you’ll need to inspect all of the wirings and make sure that everything is properly connected. You might also try using electrical tape or wire ties to keep everything in place.

Step 4:- Clean Connectors

Corroded connectors can also lead to speaker cuts out. If the connectors are not clean and free of corrosion, they won’t be able to transmit a clear sound signal. To clean the connectors, use a small brush or Q-tip to remove any debris or corrosion. Then, apply a layer of contact cleaner to help protect them from future corrosion.

Step 5:- Replace Bad Cables And Connectors

If the problem is with the RCA cables or connectors, you’ll need to replace them. You can buy new RCA cables and connectors at most electronics stores.

Step 6:- Replace Defective Parts

If you’ve tried all of the tips above and your speaker is still cutting out, then it’s likely that there’s something wrong with the component itself. In this case, you’ll need to replace the defective parts.
