BUYING GUIDE

The old saying "you get what you pay for" is true, but it doesn't have to be that way. People on a budget can find plenty of good amplifiers that don't waste their money. The list above shows that this is true. There are a lot of hidden gems on the market that are a great value for the money and won't fry you. In addition to finding a good brand or choosing one from the list above, you need to match the amplifier to your system. These are the numbers that you should check the most. The power rating is the first, and the impedance is the second. If you do this right, your system will be great.

  • Rating of Amplifier Power:

Warning! This number is not the one that is advertised as being the highest. The highest number is the maximum amount of power, which is often inflated to get people's attention. Most of the time, the amp will never get that high. The RMS value is the real number you should look at. Watts are used to measure the RMS and all other power ratings.

You need to figure out how much power your system needs. You now know that you need to look at the RMS value and find an amp that matches it.

The good news is that RMS value doesn't have to be exactly right. If you're between 70 and 100 percent, that's fine, too. If you have more power, it's not a big deal because you can always upgrade or the speakers can handle it.

When you don't have enough power, you run the risk of destroying your system.

Best Overall Pick: Acoustic Audio WS1005

  • Impedance of an amplifier:

This number, which is measured in ohms, is the second most important one. Remember that the higher the number, the harder the amp has to work and the less power it makes. Most of the time, 1, 2, 4, and 8 ohms are used

You need to look at your system and find an amp with the same impedance. This has to work, or else nothing will.

  • Classes of Amplifiers:

In the world of amplifiers, there are two important groups. There are two classes: Class A/B and Class D. Both have a lot of good points and a few bad ones.

Class A/B is an older technology that stands out because it makes the best sound. But it's not very good and gives off a lot of heat. This means that you will need fans to keep it running. Also, it is bigger than the other one.

Class D, on the other hand, is very efficient and can easily reach 95 percent. This means it doesn't make much heat and is small. This gives you more than one choice for where to put it. But the sound isn't very clean, which is a bad thing. Even so, it's getting there thanks to recent progress.

Most of the time, Class A/B speakers and Class D subwoofers are used to get the most out of them. Now, there are also other classes and systems that are a mix of the two.
