The audio power amplifier is designed to amplify the audio signal and improve the volume and sound quality to the required level. To select the correct amplifier, it is necessary that it matches the characteristics of the subwoofer being used. This will create a high-quality and durable car audio system.
Instructions
Step 1
Amplifiers are single-channel and multi-channel, which have up to 8 outputs for connecting elements of an audio system. On average, each amplifier model is supplied with 2 or 4 channels, but there are devices in which 3 or 5 sound sources can be connected at the same time.
Step 2
Decide on the type of amplifier you need. If your task is simply to connect one subwoofer, you can choose a regular single-channel monoblock, but if you plan to connect, for example, speakers to it, it is better to choose a multi-channel device.
Step 3
Think about what additional functions you would like to have in your amplifier. So, some models are equipped with equalizers for adjusting the sound, crossovers for filtering low and high frequencies, a remote control or a remote control for quickly adjusting bass parameters, as well as output channel power controls. This will allow you to use a powerful amplifier with weaker speakers, a subwoofer and a radio tape recorder. The more additional functions, the higher the cost of the amplifier.
Step 4
Check the safety of the selected audio amplifier model. Examine the number and rating of fuses, having familiarized yourself with the characteristics of the device: there is one fuse for each power supply: a two-channel amplifier will have two fuses, a four-channel amplifier will have four. The audio outputs must have the same impedance to ensure stable operation of the entire audio system.
Step 5
When choosing an amplifier, pay attention to the power balance it has. A properly sized amplifier should have less power than a subwoofer. Otherwise, the service life of the device will be significantly reduced.
