Some soothing music and a quality amplifier would never make you bored, even when you are riding all the way alone. What if your music composer stopped working suddenly from time to time? You will feel lost in a desert in that kind of situation and will be wondering why does my amp keep cutting out.
An amplifier in your vehicle or in your electric guitar will surely give you unworldly quality time and experience. Thus, an amplifier acts as a booster unit for the music emitted by the first device. (By your radio or electric guitar etc.) An amplifier increases the voltage, power, and current flowing in signals. These amplifications could be done on radio, television, computer, any audio equipment, and in any electric musical instrument.
When a cutting out happens in the middle of your relaxation or event, that will make you disappointed all of a sudden. There are many reasons affecting the malfunctioning of an amplifier.
We are going to look into those points one by one from this article and also, we will be discussing how to manage the situation if something like that happens to you. Having a piece of prior knowledge of the things that could happen is never a waste. It will make you be careful with handling, settings, storage, etc., to avoid this kind of hard luck.
Why does My Amp Keep Cutting Off?
Most often, this issue could be seen in high volumes. If your amplifier has a problem or it is some other unit in the settings, you will lose the connection all at once. The improper functioning of speakers might also be a reason for the cutting off. At last, it would be an electrical problem too.
Why does my amp keep cutting off is a question that can be answered by the settings, connected devices, and the electrical side of your vehicle accordingly. Let’s clarify one by one.
Problematic Speakers
Sometimes the speaker may burn out as a result of the over-received signals from the amplifier. When it is over the limit, the coil placed inside the magnetic field will be broken, and the circuit will become uncompleted. Or else it will be merged and form other circuits. This is called short circuits.
You can identify an uncompleted circuit and a shorted circuit from an ohmmeter that specializes in detecting disconnected circuits. If the circuit is broken(uncompleted), it will give an infinity reading because the current flowing cannot be continued after the broken point.
If it is shorted, it will give zero ohms in the scale reading as sending current through itself repeatedly is the feature seen in such types of conditions. This will make it overheated and even could explode if it happens for a long period.
If you hear sharp noises every so often, it may be due to damage that happened to the speaker, as we discussed in the above passage. If you detect such a thing, please do not hesitate to change the speaker because the more time you get to replace it will cause more damage to the entire system, including the amplifier.
Damages Occur in Connective Wires
When the connection has failures, the sound may become popping and cracking. When in such a case, the current is touched by the lower body of the vehicle; consequently, the amplifier will lose the connection and will be shut down.
You can check this by removing all the wire connections and playing once and again doing a test playing with the wires connected. You will find a wire that gives cracked music or non. After identifying it, you can simply replace the wire with a new piece.
The Downfall of the Amplifier
When in places like we discussed in the first reason, the amplifier will break down if the current flow is more than the standard. You can check this on your own by the gain knob. The gain knob is not used for sound adjustments and is used in controlling the voltage given by the radio to the amp.
If you set this to a high-level value, the amplifier works more, and overrun will make it down. This will even cause a transistor failure, overheating speaker, and a probability of catching fire.
A broken and overheated amplifier could be detected easily by touching the surface where it is placed. This may be placed down the luggage compartment, between the seats or under a seat.
Having a cooling fan and cleaned air flowing paths will lessen the temperature of the overheating circuits.
Small Power Supply Than the Required Amount
If the amplifier does not receive the required power, then there will be a thermal failure, and it will not perform its function. An 8-gauge power supply and a ground cable below 18 inches will result in high efficiency of transmission of power.
Low power issues can be identified by measuring the voltage using a multimeter. The voltage must be over 12.5. If the reading is lower than that, you need to charge your battery. Keeping an extra battery is also ideal for getting more constant power to your amplifier. The same process could be done by a capacitor. It stores energy and releases it when you turn on your radio and start enjoying a round of music.
What Causes the Amp To Cut Off at High Volumes?
There are several reasons affecting the popping sounds or the cutting off of the amplifier. We have given the reasons along with the ways to overcome them from the above passages.
In short, it could be a problem with your amplifier, power supply, supporting components or speakers, etc.
Conclusion
Amps are cut off due to various reasons. If you need to do a remedy or a replacement, first, you have to identify the reason for the failure of the amplifier. If you ever detect such a non-performance, you must take immediate action to recover it before damaging the whole system.
We have described many ways that an amp goes out of action, together with some precautions you can get from this article.
