Remote Subwoofer Control Not Working [What to Do?]

Music without bass doesn’t give the right feel to it. A subwoofer’s job is to provide that bass to make your listening time more wholesome.

But what if it suddenly fails to work? The sound quality drops tremendously to the point the song doesn’t even sound the same.

So what to do if your remote subwoofer control not working?

Your remote subwoofer can fail due to various reasons. There’s a possibility that the amplifier is running on little to no power. Checking the voltage would discover the issue. Mismatched input ports or a faulty remote controller can also be a reason. If it’s none of these, check the inner circuit.

Need more details on these processes? We can definitely provide you with that. Just follow us along until the end.

Let’s begin!

Remote Subwoofer Troubleshooting

Your remote subwoofer can start malfunctioning due to various reasons. First, you need to pinpoint where the problem is. Then you can go for the solution.

If you’re in need to figure out the problem then you’re in the right place. We’ll discuss the possible reasons why your remote subwoofer isn’t working. 


We’ll also talk about how to fix a subwoofer with no sound. Ready for the ride? Let’s start.

Inspect The Amplifier Power 

Marantz amplifier remote also faces this problem. So it’s only natural that amplifier power is messing up the subwoofer and it’s remote. If your subwoofer is not getting any power connection then naturally it wouldn’t work. Because it’s an electric device. The voltage in the amplifier is what keeps it going.

So, if your subwoofer control is not working check the amplifier’s voltage power. A common issue with subwoofers is that they sometimes run on low voltage.

If it runs on low voltage power it’ll stop functioning. Because in low voltage subs can’t receive signals. So, you should check the voltage power level in the amplifier.

Use a voltmeter to calculate the voltage in both negative and positive terminals. The reading of the terminals should be between 12 to 14. If you see a result lower than 12, the amp is running on low voltage.

You should check the power and ground wires located in the fuse block. Also check the grounding bolt, battery connection, or any other adjacent point. All the connection wires should be affixed properly.

Sometimes, the fuse is the reason for messed-up voltage. The blown subwoofer fuse fails to deliver the right voltage at the amplifier terminals.

Fixing a blown subwoofer is quite a hassle. It’s better to go for subwoofer fuse replacement. Make sure to get the subwoofer fuse size right while replacing it. Also, mind the amp size of different subwoofers

Mismatched Input-Output in the Amplifier 

If the subwoofer has power but is still not working then check the input-output ports. The input port should be connected to the head unit with an RCA cable

In case you have more than one RCA output port, test on them as well. See if you can get any response from the sub. These RCA cables supply the signals to the amp. 

So they must be connected to the right port. Otherwise, it won’t work. But if the cable is connected fine then the problem is within the head unit. 

If the head unit is the problem you’d have to step up your game. Better would be to leave for the professional hands.

Check the Remote Wires

there‘s a big possibility that the problem lies with the remote controller. Have you checked its condition? If not, do check it now. Especially the wires.

The wires that are used in the remote advance from the radio. Subwoofer remote bass control wire has a very important role in the sound system. 

In case they are damaged, connected incorrectly, or become faulty, problems will arise. The wires will fail to supply the correct output to the remote subwoofer control

That’ll result in the failure of the control unit. So make sure the wires are in proper condition. While you’re at it do a primary check on the remote circuit as well.

Here are some subwoofer remote control that you can get for great value:

Subwoofer Short-Circuited?

Subwoofer short circuit is quite a common issue for speakers and subwoofers. It happens if the positive and negative rods at the terminal touch anything metallic.

It’ll result in an instant short circuit. It’s also hard to discover this issue. You can only detect it when you power up the amp. There’ll be no sound coming out of the subwoofer.

In this case, connect the subwoofer with a different amp. See if you can hear any sound from the sub. If there’s no response from it then probably the wires got burned.

As a result, no electric signal is being passed to the sub. So the control unit isn’t working. 


Faulty Electromagnetic Coil & Cone Seal

Do you see the amp has power but no sound from the subwoofer? Then the problem could be in the cone seal and electromagnetic coil.

To be sure that your suspicion is legit you’d have to do a comprehensive test. To do that you’d have to open the sub first. 

Get to the inner components and check the cone connection in the rear end. Also, check whether the sub low pass filter is turned on. 

The cone is in charge of supplying the last audio output. So it is supposed to move forward and backward to push and pull air. With a broken seal it won’t move as it’s supposed to. 

As a result, you won’t hear sounds. Similarly, if the subwoofer’s electromagnetic coil gets burned it’ll fail to produce sound. So, this is another potential cause that you could be looking for.

So which one was your issue? Figured it out yet?


Before we wrap up, here’s a little more information you may find a use of-

How to fix the subwoofer low volume problem?

Press the plus button from the volume section of the remote controller of your subwoofer. Set off the night mode if it’s on. Now do a demo music test on the subwoofer. To find the process look in the user manual. Different models have different setting systems.

How to tell if the subwoofer fuse is blown?

Subwoofer fuses get blown when it receives too much-distorted signal or high power. To detect a blown fuse lookout for the movement and the sound of the sub. You can also use a multimeter to measure up the power supply.

What is the difference between passive and active subwoofers?

Active subwoofers have a built-in power source and amplifier in them. So, they only require audio sources. But passive subwoofers need an extra amplifier or receiver as a power source.

Final Words

So, have you figured out yet why your remote subwoofer control not working?

Always check up the wires and connection settings if the subwoofer isn’t working right. At least, then you’d have an initial idea of what’s gone wrong with it.

That’s it for today. See you next time!
