If it’s plugged already, unplug it. Remove the RCA cable from the head unit and reconnect it again. When reconnecting again, first inspect the cables to see any breakage.
After reconnecting the RCA cables, turn the unit on. Check whether every input is working properly.

If you check your inputs and find them working properly, but still, you can hear any sound in your subwoofers, then you need to look at your wiring.
3. Check Your Wiring
Wiring is one of the issues that will make your car subwoofers to fail even when AMP has power. The subwoofers are connected to speaker wires and power sources.
This wiring is mostly found underneath the dashboard. And if there is a problem with the wiring, then the subwoofer won’t work.
Therefore, check subwoofer wiring and ensure there are no damages.
As you inspect the wiring, it’s essential to start with the fuse. The fuse blows up when there are power upsurges in your car. It blows to break the circuit and prevents further damages to the subwoofer.
Car wiring can be complicated. Unless you are an expert or confident with checking it yourself, we recommend that you get a skilled mechanic to check the wiring.
An experienced mechanic will easily identify and fix any wiring issues in your car.
4. Check the Speakers
After you have checked everything else and nothing seems to be the problem, it’s time to check your speakers.
Sometimes the speaker wire get’s loose or broken. This happens mostly when the subwoofer is overheating – something which is common.
Other times your speakers could be completely damaged. And if the speakers are damaged, they won’t work despite all other components working perfectly.
So, when the speakers are damaged, the next thing to do is remove and replace them with new and quality speakers.
But before you buy any speaker, first check the power level of your subwoofer and buy a speaker that will easily be supported by your system.

Experiencing a car subwoofer that’s not working despite a powered amp can be frustrating. Let’s explore some simple checks you can perform to identify and resolve the issue.
What Should You Check First:
- Subwoofer Connections: Inspect the wiring connections between your subwoofer, amp, and head unit. Ensure that all cables are securely connected, and there are no damaged or loose.
- Amp Settings: Verify that the amp’s settings are correctly configured, including the low-pass filter, gain, and bass boost. Incorrect settings could cause the subwoofer to remain silent.
- Subwoofer Fuses: Check the subwoofer’s fuse to ensure it’s not blown. Replace any damaged fuses to restore power to the subwoofer.
Still Not Working? Here are some additional troubleshooting tips:
- Swap the Subwoofer: If you have access to another subwoofer, try connecting it to your existing setup. This will help you figure out if the problem lies with the subwoofer itself or the wiring and amp connections.
- Test Subwoofer Impedance: Using a multimeter, measure the subwoofer’s impedance to ensure it matches the amp’s output impedance. A mismatched impedance could cause the subwoofer to malfunction.
- Inspect the Voice Coil: The voice coil in your subwoofer may have been damaged due to overheating or overuse. Inspect it for any visible signs of damage or burnt coils. If damaged, consider replacing the voice coil or the entire subwoofer.
FAQs
Here below I’ve listed the most frequently asked questions about what to do when a car subwoofers aren’t working but the amp has power:
How do I know if my subwoofer fuse is blown?
To check if your subwoofer fuse is blown, you need to remove it from its holder and then inspect it. If you suspect a blown fuse, then you should see a melted or broken metal wire inside the glass or plastic casing. Alternatively, use a multimeter to test for continuity; no continuity indicates a blown fuse.
Why does my car subwoofer keep cutting out?
A car subwoofer cutting out can result from several issues, including loose connections, overheating, incorrect settings, or insufficient power. Checking wiring and amp settings to ensure proper ventilation to prevent thermal shutdowns. Verify that the amp supplies enough power to the subwoofer.
Why are my subwoofers getting no sound?
Subwoofers with no sound may have issues with wiring connections, a blown fuse, or incorrect amp settings. You must inspect connections, replace damaged fuses, and verify amp settings. Additionally, if the problem persists, consider testing the subwoofer’s voice coil for damage or impedance mismatch with the amp.
Parting Shot
Every time your subwoofer doesn’t work, but the AMP has power, start by checking the volume level. If the volume is okay, the next thing is to inspect the inputs and ensure they are working correctly. Then if that doesn’t solve the problem, check and fix in faults in wiring. But if none of those hacks works, check your speakers. If you notice any problem replace them.
