How Many Watts Is A Good Amplifier?

Generally, when matching an amplifier with your speakers, you should select one that can deliver power equivalent to twice your speaker’s continuous power rating.

For instance, if your speaker has a “nominal impedance” of 8 ohms and is program-rated at 350 watts, it should be paired with an amplifier that can output 700 watts into an 8-ohm load.

Is Monoblock A Good Amplifier?

Monoblock amplifiers are also called one-channel or single-channel because they bear only one channel per chassis.

Since they have only one channel, all the power is dedicated to that channel, helping them deliver superior power amplification. Monoblock amps are, therefore, among the most highly regarded types of amplifiers.  

Some of the companies that manufacture the best Monoblock amps are Rockville (check out our guide on Rockville Amps to learn more), Planet Audio, Rockford Fosgate, Boss Audio, Skar Audio, UdioPipe, and Kenwood. To choose the best amp, you need to evaluate the different available amplifiers so that you can pick one that matches the needs of your speakers and other components of your audio system.
