Skar Audio RP-2000.1D Monoblock Class D MOSFET Amplifier Review

Are you looking to upgrade your car’s audio system? Then a car amplifier is a must-have! Often when it comes to car audio upgrades, usually people are tend to be drawn to loud speakers and booming subwoofers – am I right?! Most tend to neglect souping up their car stereo system with an amplifier setup!  

When it comes to power, you just can’t go on without a solid amplifier powering those monstrous subwoofers you got going in the back of your truck! If you are looking for a solid quality amplifier to really complete the set, take a look at the Skar Audio RP-2000.1D Monoblock Class D MOSFET Amplifier. This amplifier from Skar Audio is the real deal, especially for its price pointtake a look at the review to see if it’s the right fit your car audio needs! 

Why Does Your Car’s Audio System Need an Amplifier? 

Basically, what an amplifier does is take a small voltage signal and use it to control another, larger voltage signal.

In doing so, what it does is it amplifies the inaudible line-level signal from the source until it’s capable of driving power towards the speaker system.

On their own, most head units are plenty capable. However, they don’t nearly have enough power to let you enjoy all of the capabilities of your car’s audio system. This is why you’ll notice either some audio clipping or buzzing, especially at higher volumes.   

By installing a car amplifier, you let your ears enjoy the full-range of sound that your car’s audio system is capable of producing.   

The improvement in audio quality is significant and noticeable, especially for those who have high-quality subwoofers and/or tweeters installed in their systems.  

Now, if you’re wondering what the MOSFET means in most amplifiers, including the Skar Audio RP-2000.1D, it stands for Metal Oxide Semiconductor Field-Effect Transistors.   

This is a kind of field-effect transistor. It features a gate separate from its body and is equipped with an insulating layer. Basically, what happens is that the amplifier can change the voltage, effectively allowing it to switch and amplify electronic signals with ease and safety without wasting energy or causing distorting or long-term damage to your car’s audio system.  

What Makes the Skar Audio RP-2000.1D So Good? 


The complex design of Class D MOSFET amplifiers seems to have a bit of a negative reputation. However, it’s not without its advantages. In fact, there are many advantages to its complex design. This includes, among others, lighter weight, less heat, and better efficiency.  

Using this design, the Skar Audio RP-2000.1D is an incredibly light yet power-efficient amplifier.

Premium-Quality Internal Components 

A car amplifier is only as good as what it’s made of and Skar Audio equipped the RP-2000.1D with some of the best and highest-quality internal components out there.   

Among these many components is a high-efficiency heatsink design, advanced PCB board, as well as a high-speed MOSFET supply. These three combine together to guarantee maximum reliability and performance.

4-Way Protection Circuitry  

Using a 4-way protection circuitry design for the Skar Audio RP-2000.1D allows the car amplifier to isolate the individual circuits of the amplifier. This guaranteed protection of all the intact circuits in case one of them fail. This effectively prevents a total failure in such emergency scenarios, including but not limited to voltage, speaker, thermal, and circuitry failures. 

Remote Subwoofer Level Control 

This isn’t a deal-breaker, but it’s a nice feature to have. This is especially true for those who would like to have better bass in their cars, as, paired with its bass boost function, the RP-2000.1D lets users have full control over the bass levels of their audio system right in the comforts of the driver’s seat. 


The RP-2000.1D comes with a variety of useful features that make it versatile. This includes a subsonic filter and a low-pass filter.  

2,800-Watt Peak Power Rating

Even though the RP-2000.1D is rated at a 2,000W power rating at 1 Ohm, it’s certainly well capable of punching above its weight. In fact, it has a maximum power rating of 2,800 watts at 1 Ohm. This gives you a lot of headroom to work with, especially if you plan on pushing your car’s audio system to its limit. 


  • Compact and versatile design
  • 4-Way Protection Circuitry 
  • High-Efficiency Heatsink Design 
  • Bass Boost with Remote Subwoofer Level Control 


  • Better options exist without costing so much more 
  • Prone to overheating and instability when switched to 2-ohm operating load 

Final Thoughts 

Is the Skar Audio RP-2000.1D one of the best amplifiers out there? Not exactly. But is it one of the best in its class? Well, it’s certainly right up there, especially when you consider its relatively low asking price.   

In addition to its affordability, it’s reliable and incredibly efficient.   

Basically, what we’re saying is, you can’t really ask for more at its price range. However, keep in mind that this model is prone to overheat and instability when operated at 2-ohm. But, if operated normally as to how it should be, this is a high-end amplifier that should satisfy your ears and last you for a long time.
