3000 Watt Monoblock Amplifier

Like we already mentioned, 3000-watt Monoblock amplifiers output a maximum of 3000 watts of power. They are single-channel amplifiers that only serve a subwoofer and are not bridgeable. Besides, they are very efficient and more powerful. Some of the best 3000 watts Monoblock amps in the market include:

1. Rockville RXD-M2 3000 Watt

The amp is cheap, CEA-compliant, and comes with a wired bass level remote. It is a compact stylish amplifier with RCA inputs and preamp outputs. It also comes with adjustable low-pass and subsonic filters.


  • Stable at 1 ohm
  • Strapping capabilities
  • Compact and slim
  • CEA-certified RMS power outputs


  • Lacks high-level inputs
  • Actual power outputs are much lower

2. AudioPipe APCL 30001D

This is a good balance between performance and price. The mono amp is powerful, affordable, and power ratings are very accurate. If you are shopping for under $400, this class D amp with an RMS output of 3000 Watts at 2 ohms is the best. The amp is however not stable at 1 ohm.


  • RCA low-level inputs
  • 4-way protection
  • Adjustable phase
  • Bass boost


  • No high-level inputs
  • No strapping capabilities
  • Unstable at 1 ohm

How Many Watts Is A Good Amplifier?

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

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 only that channel helping them to 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, 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.
