Check for blown fuses and if necessary, replace them. Add the audio cables to the amplifier first and make sure the cables are securely connected. Then test the amplifier to make sure there are no issues. Add the speaker wires one at a time to make sure the connections are accurate and secure.
Commonly, a blown subwoofer, issues with the connection and wiring, volume and other settings, input problems, short circuits and issues with the speaker can be some potential reasons behind a subwoofer not working even if the amp has power.
Why is my amp getting power but not working?
If the ground connection is poor or isn’t connected at all, the amp might fail to turn on or not work very well. If the amp has good power and ground, the remote wire has voltage when the head unit is turned on, and no fuses are blown, then you’re probably dealing with a busted amplifier.
How can you tell if your amp is blown?
The most common aural indication of a blown speaker is an unpleasant buzzing or scratching sound, by itself or roughly at the pitch of the note the speaker is attempting to reproduce. Or there could be no sound at all.
Why is my car amp on but no sound? – Related Questions
How do you know if an amp is fried?
How do you diagnose an amplifier? Test the sound by unplugging the sound cables or colored RCA wires. Hissing and crackling are often easy to fix by rearranging the wires or getting complimentary speakers. If the noise doesn’t stop, then you probably have a faulty amp to replace.
Will amp turn on if fuse is blown?
If the fuse is present and blown, the amp can’t turn on because the circuit providing mains voltage is open. Simply replacing the fuse may or may not solve the problem.
How do you check if an amp is working?
How To Test An Amplifier
Attach the wires for power (red) and ground (black).
Touching the amplifier’s electricity wire to the car’s battery positive post and the ground to the negative battery post is one of the easiest things.
Link the amplifier with a mic.
Check all accessible fuses and use one fuse in the amplifier.
How does an amp get blown?
How Does An Amplifier Get Blown? An amplifier can get blown by a sudden increase in voltage, by a short circuit, or by overheating. If the voltage is too high, it can damage the transistors or other components in the amplifier. If there is a short circuit, the amplifier can get hot and overheat.
What causes an amp to burn out?
the amplifier is malfunctioning
If a component dissipates too much heat, or experiences excessive voltage, it may start to burn up.
What happens when a fuse blows in an amp?
The immediate symptom is the same as for an overload—the metal ribbon inside the fuse burns through and all lights and fixtures along the circuit go dead. But in the case of a short circuit, merely replacing the fuse will likely cause the new one to blow immediately—unless the short circuit has been fixed.
Can you tell if a fuse is blown without taking it out?
The blown fuse will be apparent because the wire element within will have melted or burned from the higher electrical current. You can also use a test light or a multimeter to identify the dead fuse without having to pull it out.
What can damage an amp?
The two most likely possibilities for damage are: – Connecting the speakers incorrectly, putting a heavy load on the amplifier and overheating it. Usually one channel goes before the other. – Cranking up the volume on the amp and ruining loudspeaker driver(s).
Why is my amp not turning on?
Check the wiring to make sure the amp is plugged in.
Go over all the wires, double-checking that they are plugged in correctly. If the amp doesn’t activate at all when you turn it on, the problem could have to do with the power supply. Sometimes you have to contend with a loose cord, which is a very easy fix to make.
How do I reset my amplifier?
How do I manually turn on my amp?
Can you fix a broken amp?
Modern audio equipment is built using delicate components that cannot be repaired; instead, they are replaced. Your audio professional will know which ones to replace, where to get them, and how to do the job. Use a clean pencil eraser to clean cable pins on a regular basis.
What is the lifespan of an amplifier?
A solid-state amp usually lasts more than 30 years even if you play it every day. Tube amps have a similar lifespan, but they require additional work like re-tubing every 2 years.
