8 Best 3000 Watt Amps RMS (2023)

You’ve come to a good place if you’re looking for the best amp to fit your car stereo system. This article will explain everything you need to know about car amps.

It can be difficult to buy a car amplifier, especially if it is your first purchase. It’s normal to be confused about power ratings, impedances and crossover filters as well as wiring kits.

This article will provide all information about car amps. We’ll discuss the importance and characteristics of car amplifiers in car audio systems, as well as the differences between different types.

Because it is important to know the differences between advertised and actual power ratings, the largest portion of the introduction is dedicated power ratings. This article’s most fascinating section is the list of 8 Best 3000 Watt Amps RMS. Here you will find interesting suggestions.

The Importance and Usefulness of a Car Amp

An amp is required for every speaker in your car to function. Many cars today have some type of amp, but these amps are often very weak.

These may be the right match for your speakers but if they are not, you will need to get a new amp if you want them to sound better and louder.

Your new speakers won’t sound as good without an amp. They will sound exactly the same as their predecessors.

It’s not worth upgrading your speakers if your car amp isn’t upgraded. Even if your speakers aren’t upgraded, connecting them with a more powerful amp can improve their performance.

A car amplifier is an integral part of any car’s audio system. A new amp is required for any upgrade, such as replacing speakers or adding subwoofers.

Different Types Of Car Amps

We can distinguish mono, stereo, and multichannel amps based on the number of channels (speaker outs).

Monoblocks and monoamps, also known as monoblocks or monoblocks, are 1-channel amps that are used to power subwoofers. Monoamps are very efficient and powerful.

Depending on which output configuration is used, one monoamp can power one, two or three subwoofers.

Stereo amps, also known as 2-channel amps, have two speaker outputs. They can power two speakers or, if bridgeable (which it almost always is), one subwoofer in bridged modes.

Multichannel amps can power multiple speakers simultaneously. Although they may not be as powerful as stereo or mono amps , they can power multiple speakers more efficiently than two amps.

You can also divide car amplifiers based on the type of amplification. The most popular amp types are Class-AB amps and Class-D amps.

Mono amps are not permitted to use Class-D type for their efficiency, lower operating temperatures and good bass reproduction.

Because they offer better midrange and bass reproduction, Class-AB amps can be used with smaller speakers.

Class-AB amps perform better than Class-D amps in terms of operating temperatures (they heat up faster) and efficiency, but quality of sound is more important. That’s why Class AB amps can be used for mids and bass while class-D amplifiers can be used for bass.

Although Class-AB amps are capable of powering subwoofers, they can’t be used to provide reliable and stable performance. Class-D amps will deliver better results.

There are also hybrid multichannel amps that some manufacturers make. There are hybrid multichannel amps that have 5 speaker outputs and 1 output with a digital amplifier (amps such as Rockford Fosgate T1000X5ad).

The plans of your organization will determine which amp you choose. A mono amp is the best and most practical option if you are adding a subwoofer or speaker to your car’s stereo system.

A multichannel amp is better if you plan to replace other speakers. A two-channel amp will work best if you are replacing your front speakers only and don’t intend to upgrade.

The easiest part of your search is choosing the right number of channels. Next, you need to search for impedances and matching power ratings.

Our Top Picks


Finding the Right Power Supply

It is easy to find the right amp for your speakers. It is important to verify the specs of your speakers (or any other speaker) and determine their RMS power rating and impedance.

You should then look for an amplifier with a matching or preferably higher RMS power output to match the impedance.

An amp with a lower impedance will cause excessive heating and not provide the desired results.

Clipping can also occur, which could cause damage to your speakers. A higher output amp is highly recommended. It will allow you to have more headroom, and will not cause damage to your speakers.

You don’t need a 3000W RMS monoamp to power a 1000W RMS subwoofer. You can choose between a 1200W RMS monoamp or a 1500W RMS monoamp.

Must Read Best 5000-Watt Amps

Things aren’t always so easy in practice. False advertising is the biggest problem. The biggest problem is the false advertising by some manufacturers, especially those who make cheap amps.

Some manufacturers use numbers that are not related to the actual outputs. Some manufacturers only provide the maximum values, which are less important than RMS values. Always look for RMS values. S

O, it is not enough to check the specs. It is important to dig deeper.

You can calculate the peak power output if you know the type and fuse ratings of the amplifier. This rating can be found in most user manuals.

Although we have said before that max output is less important than RMS output, this can still be true. However, it can help you to understand what to expect from an amp.

If the actual power output is lower than the advertised max, you can rest assured that the amp cannot deliver the advertised power output.

This equation is a practical version of Ohm’s Law. It can be used to calculate the estimated power output of any amp.

The CEA certification is another useful tool. CEA2006 defines the measurement procedures for RMS power outputs in car amplifiers. An amplifier with CEA-certified RMS ratings can guarantee that it can deliver the RMS power outputs.

You should search YouTube for amp dyno testing. These tests are the best way to determine the RMS outputs (certified test), but there are not amp dyno testing for every amp.

These tests can also provide a guideline for what you should expect from a particular brand. If there are multiple tests that are done on the same amp and the output values are consistent, then you can be confident in that manufacturer.

Now you’re familiar with the main facts, let’s move on to our list of 8 top 3000-Watt amplifiers.

This list contains amps that advertise as 3000-Watt amplifiers, but not all of them deliver the advertised outputs. Sometimes, the actual power outputs are much lower than advertised.

This list is broken down into three groups: best 3000-Watt amplifiers under $100, best 3000-Watt amplifiers under $200 and best 3000-Watt amps over $200.

It’s as easy as setting a budget and finding the right amp. One thing we can tell you is that amps should not exceed 3000W peak or RMS. This means you need to spend at least $100 and preferably $200.

Best 3000-Watt Amps Under $100

This category has only one amp, and it isn’t very good. Although it is better than the 3000-Watt budget amps, that doesn’t mean it’s good.

You will have to spend more if you want a decent 3000-Watt amp.

1. Planet Audio TR3000.1D

Editor’s Rating: (3.9 / 5)

It is true that no cheap amp under $100 can deliver 3000W. Not even in bursts. Their power outputs are lower. Planet Audio TR3000.1D does not make exceptions. It is slightly less efficient than the other models. TR3000.1D is an amp that’s a mono-amp of Class-D.


Your TR3000.1D amp, wired remote for bass, mounting screws, user guide, and 1-year warranty are included in the package. The wiring kit is not included.

The amp looks stylish, compact, and a bit pricey (due to the plastic parts). It measures 13in in length, 10.7in width, and 2.4in high.

Only RCA inputs are available for the amp. The amp does not have speaker-level inputs. You will need an adapter to connect it with your factory receiver. You can also use the amp’s RCA line outputs to strapping.

TR3000.1D has variable low-pass and/or subsonic filters. The low-pass crossover range is between 50Hz and 250Hz, while the subsonic crossover spans between 15Hz-40Hz.

You can adjust the amp’s bass boost knob to increase your bass response up to 18dB. The bass remote can be installed if desired, but it is not necessary. You can also install the phase switch (0-180deg).

Although the amp’s maximum output is 3000W, it can’t exceed 3000W. This amp can power up to 700W according to our calculations. YouTube has one amp Dyno Test for this amp, which shows lower power outputs.

The specs state that the amp can output 2250W continuous at 1 (it’s1 stable), 1125W @ 2, and 563W @ 4.

These outputs are all a bit overrated. The amp could power a subwoofer of 300W RMS, but that’s likely its limit.


  • Design-friendly and compact
  • RCA line inputs and RCA outputs
  • Strapping capabilities
  • Variable low-pass filters (50Hz-250Hz), and subsonic filters (15Hz-40Hz).
  • Bass boost (0-18dB) & bass level remote

6. Hifonics BXX3000.1D

Editor’s Rating: (4.7 / 5)

Check Last Price

Hifonics is a brand that has been around for over 35 years. Hifonics amps were hugely popular in the 1990s. They were powerful, reliable, and very expensive.

Although Hifonics amps remain competitive, they are not as good as they once were. The Hifonics Class-D mono amplifier, the BXX3016.1D, has a power output of 3000W. This model is very similar in design to BRX3016.1D. Only difference is the slightly lower RMS power output.


An amplifier includes a remote control for bass, mounting screws, a user manual, and a warranty card. The wiring kit will cost extra. For the power terminals, you can use 1/0-gauge and for the speakers, 10-gauge.

Hifonics’ iconic design features are evident in the amp, including a shiny aluminum chassis and large heatsinks. The amp also has an illuminated logo, speaker outputs and a glowing logo. The amp measures 19in in length, 10in width, and 2.5in high.

Inputs are limited to RCA (low level) inputs. There are no high-level inputs. If you wish to connect two amps and achieve higher output, the amp has slave-in and master-out RCA ports.

BXX3000.1D has variable low-pass and/or subsonic filters. The subsonic range is between 15Hz and 35Hz, while the low-pass crossover range covers from 35Hz to 250Hz.

You can increase the bass to your liking by up to 10dB. The amp’s bass knob can be used, or you can use the included bass remote. If you need to adjust the bass response, you can use the phase switch.

250A inline fuse, amp fused at 250A. It’s class D fuses it to 80% efficiency. The equation in the introduction will give you the approximate. Maximum power output is 2880W

The specifications in the manual are vague. Although the manufacturer gives numbers, they don’t provide any information about the output type (RMS/Peak). These are all RMS values. We can conclude that the outputs are slightly overrated.

According to the manufacturer, BBX3000.1D is capable of pushing 3000W at 1, 1400W 2 and 700W 4 respectively. Although we couldn’t find any amp-dyno testing for this amp, our experience suggests that it can push 2500W continuously at 1.

Although it isn’t bad considering the price, it doesn’t have the same power output as the advertised. It can power one to two subwoofers of 1000W/2.


  • Low-level RCA inputs
  • Slave-in RCA outputs and Master-out RCA outputs
  • Strapping capabilities
  • Variable low-pass filters (35Hz-250Hz), and subsonic (15Hz-30Hz) filters
  • Bass boost (0-10dB) & phase switch (0-180deg).

Audiopipe is our favourite when it comes down to price and performance. Audiopipe amps have powerful power ratings, are accurate in their advertised power ratings, and are extremely affordable.

APCL 30001D, the most reliable amp at 3000W under $400 is the best option. This is a Class-D monoamp with a RMS output of 3000W (at 2.). This amp’s only problem is its inability to stabilize at 1.


Your amp, remote control, manual and warranty card are included in the packaging. The wiring kit is not included. For power terminals, you can use either 1/0-gauge or 10/12 gauge wire.

The amplifier has the AudioPipe design, which includes a black aluminum housing and a silver grille underneath. There are also long heatsinks to the left and right. The amp measures 27.9in in length, 7in wide and 2.2in high. The amp is the longest 3000W amp on the market. It will need some planning.

APCL 30001D features RCA (low-level) inputs. This amp doesn’t feature high-level inputs and RCA preamp outputs. This amp does not have strapping capabilities.

Variable low-pass and subsonic filters are available on the amp. The low-pass crossover range is between 40Hz and 180Hz, while subsonic crossover spans between 5Hz and 50Hz.

You can increase the bass to 12dB if you enjoy bassy music. The amp comes with a bass remote and a bass boost knob. You can select the frequency that you wish to boost (30Hz-80Hz), and also change the phase (0-180deg).

The specs state that the amp can output 3000W continuously at 2 and 1800W at 4. Our calculations indicate a lower maximum power output value (2304W), however has an amp dyno that proves that APCL30001D can push 3000W under 2 loads.

The amp offers 4-way protection: overheat, overload and low voltage.

  • Bass boost (0-9dB)
  • Performance stable and reliable with 1500W RMS output (at one load)


  • No high-level inputs
  • Not too strappable

This is the end of our list of 8 best 3000-Watt amps. If there was nothing you liked on the list and if you want to keep searching, here’s a short buyer’s guide with some tips on what to look for when buying a car amp.

Buyer’s guide – Things to Think About When Buying an Amp


You will need to spend more than $100 if you want an amp capable of pushing 3000W. We have found that budget 3000-Watt amps, which are less than $100, are a fraud.

Manufacturers don’t disclose the specifications and power outputs are greatly exaggerated. The amps are affordable, but they don’t have the power output to deliver 3000W.

Taramp’s HD 3000 is the cheapest amp that can push 3000W continuously. This is a mono Class-D amp. Hifonics amps are worth looking at (Hifonics BXX3000.1D, Audiopipe APCL30001D).

Amplification Type

The channels have been discussed before so it’s not necessary to repeat them all. Let’s take a look at the channels.

There are many types of amps: mono amps and stereo amps. Choose the amp that best suits your needs.

A mono amp is sufficient to add subwoofers. You don’t need a multichannel amplifier. A 4-channel amplifier with matching power outputs is best if you are looking to upgrade your car’s stereo system (4 speakers).

There are many combinations you can make. You can purchase one mono amp to power the subwoofers, and one 4-channel amp to power the speakers. To make them all work together, you will need a mono amplifier with preamp RCA outputs.

In some cases, purchasing two amps of the exact same type (for example, two mono 1000W amps) can be cheaper than buying one 2000W amp.

You don’t have many options when it comes to amplifying type. The majority of multichannel amps (analog and digital) are Class-AB amps, while mono amps (digital) are mainly Class-D amps.

While digital amplification offers some important advantages over analog amplification (lower operating temperature, higher efficiency, and higher power output), the real draw for Class-AB amps is their final product (sound).

The midrange and treble reproduction of digital amps is not the same as that of analog amps. This is why manufacturers don’t make Class-D amps.

Class-D amps provide a very good and well-controlled bass reproduction, which is why the majority of monoamps are Class D amps.

Power outputs

This is one of the most confusing topics when it comes car amps. You can avoid purchasing the wrong amp by following these simple tips.

First, it is possible that it sounds too good to true. Budget amps that boast high outputs may not be as good as they claim. They are often quite poor and have power ratings that are far below the advertised outputs.

The CEA-certified RMS power ratings are second. These ratings are very useful and accurate. Sadly, CEA 2006 car amplifier standard is not obligatory and some excellent high-end amps may not be CEA-certified.

If you have the fuse rating and type of amplifier, you can calculate the approximate output. Although this calculation won’t give you the best power output, it can help to determine the true capabilities of an amp.

You can also search for amp dyno testing on YouTube. These tests are conducted by third parties (YouTube reviewsers) or, in certain cases, by the manufacturer.

These tests are extremely accurate and give you an idea of what to expect from an amp. Although there are more amp dyno testing available, not all amps have the same test.

Common features

You should pay attention to inputs (low-level and high-level), crossover filter (high-pass and low-pass), preamp outputs and strapping capabilities.

Two types of inputs are common: high-level (speaker-level) and low-level(RCA). The amp should be selected with the correct input type.

Preinstalled car receivers today don’t have RCA inputs, but most aftermarket receivers do.

Some amps can accept both input types. Some amps only have RCA inputs. If your amp has RCA inputs but your car receiver does not have RCA outputs you will need to purchase a high-to low adapter that includes the appropriate number of channels.

Multichannel amplifiers often have high-pass and low-pass crossover filter. These filters can be either fixed or variable, and allow you to choose the frequencies that are sent to specific speakers.

These filters allow you to choose which frequencies go to the subwoofer, and which to your stereo speakers. Low-pass and subsonic filters are common in mono amps. They can be either fixed or variable.

Some monoamps also have additional RCA outputs. These outputs can be used to connect another amp in some cases. You can pair a mono amp to power your subwoofer with a 2-channel or 4-channel amp to power the other speakers.

Mono amps can also be strappable. Strapping refers to the act of pairing two amps to achieve a higher power output.


Because you don’t have unlimited space, amp size is crucial. The available space is actually very limited. It is important to consider the dimensions of your amp.

Don’t forget to provide adequate ventilation. Good airflow is essential for a stable performance of amps that can heat up quickly.


Installation is the most difficult part of any job. It’s best to hire a professional. If you’re looking to install the wiring yourself, the kits are not included in the package. You will need to purchase them separately.

It is not a smart idea to try and save money on a wiring kit. There is a reason why the price difference between the most expensive and most expensive kits can reach up to $100.

CCA (copper-clad aluminium) kits are often very affordable, but they don’t offer the same level of performance as OFC.

OFC cables conduct better and don’t heat as much as CCA cables. OfC wiring kits are a must. The best OFC doesn’t necessarily have to be the most expensive. A decent OFC kit can be purchased for as low as $60
