Car alarms are fitted with loud horns that make loud noises whenever the sensors trigger the brain of the alarm system. However, certain problems can reduce the volume of a car alarm system. This is a major problem that requires immediate attention. Why is my car alarm not loud? The answer to this question can be found in this article.

Why Is My Car Alarm Not Loud

Low battery, poor sensitivity, improper installation, broken remote fob, rusty terminals, dirty hood latch, damaged wiring, and low device volume are all causes of a low car alarm. These can also cause your alarm to go off randomly, so be sure to scrutinize these problems well before applying a corresponding solution.

Advanced security devices have menus for increasing and decreasing sensitivity and volume. You can also resolve most of your alarm problems by simply resetting the device which will be covered in the latter part of this article.

Reasons Why Your Alarm Is Not Loud

  •  Low volume

Being that several alarm systems have a volume control button, it is possible for drivers to have mistakenly reduced the volume. This happens more often than not. For example, if you find yourself in a serene environment or a secure facility where the loud alarm from your security system might be a disturbance, you may want to reduce the volume.

However, the problem arises when you forget to increase the volume. To combat this problem, we recommend that you set a reminder to increase the volume.

The alarm system itself might be low from the manufacturer. The horns that come with low-cost alarm systems are not made with quality materials. This causes all sorts of problems, including volume issues. How do you resolve this? Simply invest in high-quality car alarms such as Viper.

  • Poor Sensitivity

The remote fob is a transmitter that sends commands to the alarm computer which is equipped with high-end receivers. This is called an antenna. The antenna can be found on the windshield, behind the rearview mirror. Anyway, manufacturers have different selected spots beside the windshield.

Read your manufacturer’s manual to get the exact spot of your antenna. When the antenna is obstructed by an element, it stops working at full capacity. This is common as can be fixed by simply remounting the antenna in a favorable direction.

If the alarm is still low after fixing the antenna, then you may need a replacement. It is important to find one compatible with your security system to avoid problems in the future.

  • Damaged Horn

The horn is responsible for alerting the driver with a loud noise. The horn can be found under the hood. Check that the horn hasn’t been damaged and is working well.

If you see that it has been broken, replace it with a new one or see if you can have it patched up. You should also check for anything that might be blocking the horn. Materials from the engine may find their way inside the horn during engine maintenance. Always check it after every major maintenance to make sure it is clear.

  •  Damaged remote Fob

numerous problems come with a damaged remote fob including low alarm volume. While this may be uncommon, keeping your fob in a good working condition ensures that your system works in optimal condition. Most advanced security systems come with 2 fobs, so drivers can quickly replace a damaged fob.

  •  Low Car Battery

Your car battery powers all the electronic devices in your vehicle. To ensure that all these devices are up and running, you need to keep your battery charge. Also, all the recommended batteries are 12 volts and above. Anything below that may cause battery drain and low volume.

A device inside the vehicle usually cuts power when the battery is low so you have enough to power the ignition. Check that this isn’t the case. If not, then charge or replace worn-out car batteries.

Poor Connection To The Control Unit

Installation problems are common with alarm systems mounted and wired by amateurs. Using the wrong cables and components for a type of alarm system may cause it to function improperly. Check the connections between the horn, antenna, and sensors to the control unit (brain) of the alarm system. Make sure it isn’t loose and tighten any loose connections. Check your installation guide on how to replace cables. If you cannot wire a vehicle, then hire a professional to take care of the wiring. This guarantees correct installation.

Wrong Installation

To save money on installation, many drivers have learned the DIY process for installing different types of electronic devices in their vehicles. However, without the proper guide, drivers can make mistakes, which leads to installation errors. Since you’re worried about the audio, check the horn to ensure that it is correctly installed.

Check the wiring linking the horn to the other devices too. Warning: this process may take your time and would require tools. If you can’t seem to find your way around correcting the wrong installations, contact the manufacturer if you’re still covered under warranty.
