Best Monoblock Car Amplifiers Class D [2018 Review]

Whichever way you view it, your amplifier choice is what makes or breaks your sound system. The monoblock amplifier, or the one-channel amp, is the typical life source of your subwoofer and speaker system. They can control your speaker’s output, distortion, and bass, besides boosting your equipment to function at full capacity.

What Does Monoblock Amp Mean?

A monoblock amplifier is a single channel amp used to provide power to single channel speaker systems, such as 15-inch subwoofers. That’s why they are the typical outfit for powering subwoofer(s).

The mono amps are designed to produce a single power indicator which is perfectly suited for the low-frequency sounds (e.g. deep bass), besides boosting specific features in the subwoofer.

Mono amps are also useful when power demands increase as they are more stable at maintaining electrical current resistance, besides having the capacity to support two subwoofers connected to a single amp.

Monoblock Amp Vs. 2 Channel Amp?

The main difference between a mono amp and a 2-channel amp is with the number of channels, the power signals sent to the speakers. Mono amps have got a single channel (oriented in one direction), while 2-channel amps have got 2 (left and right) power channels.

With this in mind, we’ve put together detailed product reviews on the best class D monoblock amplifiers to help you overcome the confusion that may arise from the various configurations, technical details, and marketing angles.
