  • You hear more distortion than the music. 
  • It doesn’t turn on at all, and if it turns on, it keeps cutting out.  
  • It is losing the efficiency of producing the loud sound bass rather than producing weak bass.

Features of an amplifier you need to look while purchasing

  • What’s the warranty?

It comes as no surprise that buyers always look for a warranty. Whether it’s a tiny electric car or a giant engine, the warranty comes first. 

Unfortunately, some amplifiers bear any warranty. While some manufacturers avoid honoring the warranty, there’s a reason behind it if the authorized retailers do not purchase the product.

Because the unauthorized dealers purchase an amp. What happens to it, how they keep the amp, and how they sell it to the consumers, so they simply don’t issue a warranty in that case. 

You have to be very wise while purchasing amplifiers, and always buy it from a reputable and authorized source.

  • The size of an amplifier matters

When it comes to buying an amplifier, new buyers mostly pick the heavier and larger amplifier for cars; they assume it to be efficient in producing sound. 

At the same time, they don’t fit in the dashboard or are difficult to fit under the seat. 

Make sure it has to fit right in the dashboard firmly. Buyers might think that a large amp can store more machinery means they function better than smaller ones. 

Thanks to technology it is possible to incorporate all the necessary functions in small or even tiny amps. 

The size of the amplifier matters so, always make sure it has to be easily fitted in an area made for. 

But no matter what the size is, it has to produce mind soothing high bass as long as the warranty goes. 

  • Wiring of an amplifier

This is the most crucial thing you have to look for. Be a little wise so that the sellers couldn’t fool you on the name of “Good wirings”. 

Check the material of the wires and always choose the long wires. Premium quality amplifier wires are made of “Oxygen-free Copper, ” an excellent conductor for carrying signals. 

The wires are lasting and more durable than any other on the market. Low-quality wires are usually made of Copper Clad Aluminum. 

Though copper is a good conductor, aluminum reduces the efficiency to a great extent, it carries less current, the sole purpose of using aluminum is to provide rigidity and thickness to the wires. 

Since not all products are original on the market, you’ve to be extra careful while purchasing. Several Chinese brands are mimicking authentic products, which have no warranty and reduced durability. 

  • Ask other features

Make sure you are choosing the right amplifier for your speakers. It has to provide you with everything you need to pull off with an exceptional sound system. 

Ask the authorized sellers if the amplifier can work on the ohm load you’re going to provide it with? 

Does the concerned amplifier have a sound filter system or not? Can it work with the subwoofer? Can it directly be connected with the factory deck? 

The average working hours to avoid overheating and overloading to store durability for long. 

Also, ask if the seller can provide a professional approach and install the device in the car dashboard.

But whether they offer it or not, try not to install it yourself to avoid damages to the wires. 

You may find it difficult to buy a premium-quality amplifier with the maximum features on a low budget. 

You can get a good-quality and excellent-designed amplifier within $500. 

What are the benefits of car amplifiers?

  • Built-in car factory systems have a weak audio system because the major focus of the manufacturers is not car stereos, unfortunately. Your premium car amp can back this up. You can achieve great levels of sound, which speakers fail to reach. 
  • With the amplifier, you can tune it the way you want! You can explore various options with the device unlike your factory system with only Turn-On and “Turn-Off” buttons. You can play around with different options until you get the desired level you’ve been yearning to pull off. 
  • The benefits are not limited to the sound and bass, amplifiers are also used to control power utilization but to avail of the benefits, you have to buy a robust and high-quality amplifier. 
  • If the car battery is not enough to stand the power inputs and outputs, the amplifier shares the burden of blowing the speakers by providing them enough power.
