You think you will go on a long drive with your family, friends, or girlfriend or alone one day. So you go with them or her and want to play music for enjoyment.
But you notice the Subwoofer is not working, but its amp has power. It won’t be charming for you, and you will not enjoy that moment. In this article, we will help you know why the Subwoofer is not working, but the amp has power.
This problem can be caused by many factors, including poorly set volume, cabling problems, incorrect ports or cabling, or a problem with the sub or speakers itself. Wiring is the most typical problem.
When you face these types of problems, at first, you will check your amps’ power. If the amp is ON, you will check your cable connection. If you see the Subwoofer not working, but the amp has power, you will follow the following things.
What To Do When Subwoofer Not Working, But The Amp Has Power
After turning on the amplifier and Subwoofer, double-check the volume knobs on both the amp and the Subwoofer. You may turn them up if they’re set too low.
Gain control enables us to alter the output levels and match the bass frequencies synthesized by the Subwoofer to the main speakers. It means that it has a direct impact, although it’s not the same as the volume control.
Also, double-check the bass knob, specifically if it’s a replacement, because not all bass knobs are compatible with all amps. When you have a similar problem, this should be the first thing that comes to mind.
It might seem self-evident, yet you’d be shocked how frequently this is the case. Many people overlook the volume and assume there must be a much bigger issue if the Subwoofer or amplifier isn’t working.
That is why many people fail to turn up the level and assume their problem is much more severe. The Subwoofer, but on the other hand, could be silenced. To test this, unmute the sub by hitting the mute button repeatedly.
If none of these D.I.Y. fixes work, don’t give up. Try replacing the inputs. If your Subwoofer or amplifier isn’t working, crank up the volume and listen to see if you can hear anything puts.
Analyze Your Inputs
The following primary source of signal loss in your audio setup is the inputs. If your amplifier functions right but your Subwoofer isn’t producing any sound, there might be an issue with the information. Here’s how you hook up a sub to an amp.
Check to see if the input cables are securely connected. Check the headphone jacks as well. Also, make sure that any unsecured wires are appropriately secured.
Unplug the input cable if it is already securely connected. Examine it after removing it from the head unit for any breaks, cuts, or loose parts.
Switch on both the amplifier and the Subwoofer after reinstalling the cord. After that, power on the system and adjust the volume again to see if the inputs are working correctly.
If this doesn’t work, try changing the cords. Moreover, it would be best to be confident that your input cords are the source of the problem before changing them.
Otherwise, keep an eye out for other potential culprits, such as faulty wiring.
Wire Checking
In addition to faulty inputs, faulty wiring is another factor that can cause subwoofers to fail, even though the amplifiers are turned on.
Power and speaker wires are the two types of wires that connect to a subwoofer. If the system is installed in a car, It will hide the wire beneath the dashboard, and any issues with the wiring will prevent the Subwoofer from working. As a result, if anything else fails, recheck the wiring.
Speaker Checking
Even if you’ve looked into all of the other issues, it’s time to look at the speakers. When the Subwoofer overheats, speaker cables frequently get loose. The speakers, on the other hand, are prone to be damaged.
Fixing other devices or perhaps even the wiring connection will not remedy the problem if the speakers aren’t working because they’ve been damaged.
When you feel your speakers have been damaged, the best option is to replace them with a similar model.
Start by looking at the speaker’s or subwoofer’s power level and other speaker characteristics like impedance.
It is significant because you’ll need to change your speakers to new ones with similar specs to satisfy your home receiver’s requirements.
Analyze The Subwoofer’s Fuse
The problem might even be the subwoofer fuse in rare circumstances. For example, when there is a power failure, the fuse usually blows. It breaks the circuit and protects the Subwoofer from serious harm.
You can hire an experienced sound specialist to investigate the problem because the wiring might sometimes be intricate, mainly for different subwoofer systems.
Check A/V Receiver
When you select a music sound field option, and the speakers are set to large, no sound goes to the Subwoofer. Check the A/V receiver settings and make sure that none of the speakers are set too big.
Check Audio Input And Output Cable To Connector
Tap the center of the opposite end of the audio cable with your finger after connecting one end of the audio input cable to the audio input connection. Ascertain that the Subwoofer is correctly powered, turned on, and volume adjusted.
When you touch the opposite end of the audio cable, you should hear a thumping sound. If the sound does not come out, the Subwoofer may need to be serviced, and you should contact your audio professional.
Connect the amplifier’s audio output port with the other end of the subwoofer cable. The rear of the receiver is where you’ll find this. Furthermore, specific amp models will have two outputs, allowing two subs to be connected and driven.
Check The Subwoofer L.E.D. Indicator Light
Make that the A/V receiver’s Subwoofer L.E.D indicator light is on. Depending on the source of music, the low-frequency effect signal may not always reach the Subwoofer.
However, when a motion is detected, the low-frequency effect indicator illuminates.
Many T.V. networks only broadcast in 2-channel audio; therefore, It may not receive this signal. As a result, change the sound field setting to A.F.D. auto or another promising area.
It can send a simulated L.F.E password to the sub if you have a Sonny receiver. Following that, the S.W. indicator illuminates.
Power Cord Checking
Verify that the Subwoofer’s power wire is correctly plugged into an operational A.C. port. Remember that if the A.C. outlet is defective or not working, the Subwoofer will not turn off if you don’t have a power cord or your sub doesn’t have one; it’s a passive sub. So you might need to buy an active subwoofer, or you could keep troubleshooting.
Frequency Adjustment
A cut-off frequency adjustment on your Subwoofer may be available. If that’s the situation, set it to the highest setting. It allows it to send all of the low frequencies to the Subwoofer. Moreover, check and turn off the snooze function if the sub has one.
If You Hear Hissing or Other Distortion
However, if you hear a hissing or other distortion, this may damage your home’s wiring. Repair the wiring as soon as possible to prevent an electrical fire. If you hear a hiss or other distortion and believe it is caused by something electrical, disconnect every piece of equipment in your home from the power supply and test each for voltage.
If there’s no voltage, the problem is likely with the wiring itself. Repair damaged areas as soon as possible to prevent fire.
If the Protect Mode Light Turns On
If the Protect Mode light turns on, your camera is in protect mode. In this mode, all settings are locked, and no photos or videos can be taken or recorded. To exit protect mode, press the shutter button halfway down to take a picture, then release it.
Additionally, this could indicate that the system is about to shut down. Check for any errors or issues before turning off the Computer. If you found the Protect Mode’s Light Turns On and there are No Errors or Issues, Turn off the Computer.
If Nothing Works, Consider Replacing Your Subwoofer
If nothing works to get the sound out of your subwoofer, it may be time to replace it. Test the woofer’s output by connecting a speaker cable and measuring the result with an audio meter. If there is no measurable signal from the woofer, you will need to purchase a new one.
If you have a sound system that includes an aux input, it may be possible to use this instead of a speaker cable. Connect the audio output of your stereo receiver to the auxiliary input on your subwoofer and then test the result. you will need to purchase a new one, if there is no measurable signal from the woofer.
Final Touch
Follow these things, and I hope your Subwoofer will work properly. However, if you do not have enough time to fix the issue, you may get help from experts. I hope now you know what to do when the Subwoofer not working, but the amp has power.
Frequently Asked Questions
1. What Causes A Subwoofer To Stop Working?
Ans: Speaker short-circuiting is the most prevalent cause of failure. The signal will never reach the Subwoofer if the signal lines are shorted. Likewise, the electrical current and password will not get the Subwoofer if the terminals are shorted.
2. Does A Subwoofer Have A Fuse?
Ans: yes, subwoofers have a fuse. It can find subwoofer fuses in line with the subwoofer cables within the speaker chamber, and if the Subwoofer has its amplifier, the fuse can also be located there. In-line fuses come in a variety of styles.
3. Can A Subwoofer Explode?
Ans: No, however, they can catch fire instead of blowing out. I’ve had two on fire, one of which went all the way out, and I enjoy having a good time with old subs that aren’t very good.
4. Do Blown Subs Still Work?
Ans: Sure, a blown subwoofer or a damaged component of one may be repaired, but it’s not easy. You won’t be able to perform it without the right equipment and knowledge.
You should only attempt this if you are confident in your abilities. Otherwise, get an expert to take care of everything.
