How To Deal With Toyota Prius Audio System Problems?

The sound system is one of the very important features of cars in general and Toyota Prius in particular.

They are necessary to improve the quality of the trip when we have to travel many hours in the car. It helps us to relax by listening to music, news, weather forecast and so on.

When an audio system problem occurs on a Toyota Prius, they tend to be difficult to resolve because they are related to the car’s electrical system.

Sometimes, one component can malfunction and affect the entire audio system. So you may not know how to solve Toyota Prius audio system problems.

Toyota Prius Audio System Problems – Reasons And Tips

Diagnosing the source of the problem can be quite difficult if you are not familiar with dealing with the connections involved. Below we have discussed some of the most common Toyota Prius audio problems in detail.

1. Poor Subwoofer System

Toyota’s sound system is having many problems and causing drivers to have many problems when moving.

When Toyota made cheap speakers, they added an equalizer circuit designed to remove the bass from the music at a higher level to protect the speakers.

No wonder you don’t have real bass in your music. You may feel uncomfortable when the sound quality is poor and cannot help you feel relaxed.

Most OEM systems have full-range speakers designed to handle all audio frequency ranges but cannot achieve smooth end-to-end or high-end tones or frequencies.

Add a separate subwoofer to your system. This is important if you want to hear your best music because subwoofers are great for low-frequency sounds.

Before deciding to replace the entire system, you only add a subwoofer, consider your needs and favorite music.

Most popular music is using the frequency range from 110Hz to 3,500Hz. So you can decide to choose a sound system that suits your music enjoyment needs in the car.

2. About The Connection Problem

If you’ve turned on Toyota Prius audio system and you don’t hear any sound, the first thing you should check is the speaker wire connections.

Check the speaker wire that is connected to the audio source, be it an amp, radio, audio CD player, or any other device you may be using.

If all the speakers have no sound, it is possible that the cable connected to the amplifier or the head unit is broken or the connection is loose. Check your vehicle’s wiring, charger, and power supply.

Also, if you have just connected a new speaker and there is no sound, you should check that the polarity connections are made correctly.

Make sure the terminals are properly connected and that the speaker cable is securely connected to the speaker and the head unit or amplifier.

3. Problems With The Generator

When the vehicle’s generator is old and used for many years without maintenance, it gradually cannot meet its original capacity.

In this case, the car audio system may be running on batteries. If the power in the battery is completely drained, the terminal will lose power.

So, if the sound system doesn’t make a sound, you also need to have the generator checked and replaced if necessary.

4. Fuse Problem

If the fuse on your vehicle has a problem, the power unit will not receive any power. To determine the condition of the fuse, you should use a multimeter.

By checking the fuse with a multimeter, you will know the condition of the fuse on the vehicle and the problem it may have.

5. Weak Head Unit Not Enough Power

Bass is an essential part of the sound and it helps to make the sound as soothing as the listener’s emotions. But what if you just installed new speakers and you can’t hear any bass?

The most common cause of this problem can be that the head unit is too weak, can’t power the speaker strong enough to produce bass, or the speaker wire connection is not good.

First, make sure the terminals are properly connected. If there’s still no bass, you may need an extra car amplifier to give the speakers enough bass output.

6. Make A Buzzing And Crackling Sound

In most cases, the buzzing noise from the speakers is caused by the bass or the volume being cranked all the way up. Also, if something touches the speaker, it may vibrate when it vibrates. So first check if an object is hitting your speaker to cause this noise.

If the humming still doesn’t stop, check the bass level and reduce it. Alternatively, the humming could be caused by a distorted voice coil on the vehicle’s system.

If your speakers crack and pop, it’s possible that the amplifiers are so powerful for your speakers that they can’t handle the power they’re receiving. You should choose the type of speaker that is suitable for the power used if you want to replace it.

7. Amplifier Overheats And Turns Itself Off

Sometimes too high again or bass can increase the power on your amplifier, which can cause the amplifier to overheat.

If you don’t already have a cooling fan for your car, you should buy one for your car amplifier.

Amplifiers can power speakers without overheating, so it’s harder for speakers connected to the case to produce sound. So to reduce the load tries using the amplifier after disconnecting these speakers.

The connection between the loudspeaker and the amplifier must be ensured for proper current transfer. For your safety, you should equip the ground wire and power cord with the right size to prevent them from coming loose.

Wires must have an amp capacity of 8 gauge or more. If the power is not enough, the amplifier will not have enough power to transmit the power to the speakers.

  1. Hi, my gen 2 Toyota Prius radio powers on but I can’t hear a sound from the speakers. I have checked the speakers and they are ok. What could be the problem. Hope to hear from you soon.

  2. My 2017 Toyota Prius (Touring) radio shuts of and reboots off and on while I’m. I’ve taken it to the dealer twice, and each time they have replaced the radio and said the problem is fixed. But within 10 to 20 minutes after I leave the dealership the problem occurs again. I’ve taken it back again today. Waiting to hear back from to see if they have fixed the problem. The service agent I have been working with doesn’t sound hopeful that they will be able to correct the problem. Has anyone else had this problem? Was the problem resolved? How was it resolved?
