Best Car Mono Amplifiers Buying Guide
Before choosing the best car mono amplifier you should consider the following options:
1. Power Supply: Most amplifiers run on either a switched-mode power supply (SWMS) or a linear power supply.
The advantage of a switched-mode power supply is that the high voltage required for amplifying low-level signals is generated with very little distortion.
The disadvantage is that these power supplies are expensive and prone to failure. A linear power supply uses transistors to generate the high voltage required for amplifying low-level signals with little distortion.
The disadvantage is that they are prone to failure and generate large amounts of heat.
2. Class of Amplifier: There are two main classes of car amplifiers: monoblock and stereo.
Monoblock amplifiers are designed for a single channel, and stereo amplifiers are designed for two channels.
3. Watts: The number of watts an amplifier is capable of handling is not always an accurate representation of how loud an amplifier can get.
For example, a 500-watt amplifier will not necessarily get twice as loud as a 250-watt amplifier.
The ability of an amplifier to get loud is also dependent on the kind of speakers being used and the quality of the signal input the amplifier is receiving.
4. Signal to Noise Ratio (SNR): The signal-to-noise ratio is the difference between the strength of the input signal and the background noise of the amplifier.
It is used to determine the accuracy and quality of the amplifier. A higher SNR means that the amplifier is more accurate.
5. Total Harmonic Distortion (THD): Total harmonic distortion measures the amount of distortion that an amplifier is capable of producing.
This measurement is important because it gives an indication of the quality of the amplifier.
An amplifier with low total harmonic distortion will be much clearer than one with high total harmonic distortion.
While the amplifier may be more capable of producing sound, an amplifier with high total harmonic distortion will be difficult to listen to.
