A damaged connector is also one of the causes of strange phenomena in the sound you hear.

How To Fix It

Speaker distortion is an annoying phenomenon and a sign of problems in the sound system. Fortunately, you can fix the above problems easily.

Fix torn wires

As mentioned, broken RCA cables are one of the main causes of hissing in audio.

Therefore, first of all, you need to check all the cables on the car. From lacerations to bent, damaged areas, every detail can cause discomfort.

Once you find the exact location of the problem, you can proceed with the repair, as long as you have tape or similar tools ready to use to fix the wire’s tear.

The easiest way to fix the problem is to twist the broken wires and then re-bandage. However, the above treatment is not effective in the long run.

If you want to continue the repair process, you need bent connectors or solder.

You may be wondering, is soldering necessary? With digital cables, soldering is not a measure that can affect sound quality. Instead, soldering can only solve the problem related to the strength of the cable.

However, suppose you own an analog audio cable. In that case, you will have to choose a soldering method instead of the traditional repair method because the sound quality will drop a lot if you use adhesive tape to fix it.

With car cables, which are subject to quite a bit of vibration and impact, soldering is one of the more reliable ways to build a solid connection.

To have the best music listening experience and at the same time limit the problems that continue to arise, it is better to replace the old cable before with a new and more durable product.

Fix loose connection

It is easy for you to fix this problem. All you need to do is replace the connectors.

These days, you can easily find connectors both online and at auto repair shops.

You will also not have to spend too much money to be able to own a high-quality product that solves your problem in a short time.

Fix voice coils

Other than the loose connection problem above, a malfunction in the voice cord is one of the most serious and difficult to fix.

If the voice cord is broken or damaged, it is almost impossible to use measures such as soldering to repair it temporarily.

Instead, you will need to spend a good amount of money on new rod coils. In some cases, when the problem cannot be fixed, you will need a new speaker model if you want to continue to enjoy your favorite songs in the car.

If you’re lucky enough to leave the voice coil undamaged, the problem could be that it’s in the wrong place. The way to fix it is much simpler; all you need to do is open the speaker and return the coils to their original positions.

Fix damaged amplifier

Amplifier repair or replacement will require knowledge and experience, and professional tools. Are you an expert in this field or simply someone with little experience?

If you are, in the latter case, unable to perform complex operations or if you do not have the necessary tools for the repair process, it is time for you to seek the help of professionals.


In addition to the problems above, there are quite a few other reasons related to the hiss of the speaker. Here are some answers to frequently asked questions.
