It is important to understand what bridge mono mode is in the context of amplifier modes. In general, modern power amplifiers have two independent channels which are usually referred to as channel A and channel B. These are identical and can be deployed in several different configurations. With bridge mode, a single input signal connected to channel A is routed to the inputs of both channel A and B. The physical input of channel B is not used. In this case, the polarity of channel B’s output is inverted. With this mode, you achieve two channels working in opposite directions. In simple words, channel B with its positive voltage pushes speaker cone, while channel A with its negative voltage pulls loudspeaker cone. Please, note this connection is not suitable for connecting subwoofers. It is great for the amplifier’s connection to loudspeakers only.

This amplifier distinguishes with its well-developed short protection. That is why customers do not need to worry about voltage swings and possible equipment damage that could be caused. In addition, the manufacturer has constructed the device with special backlighting. This technology contributes to the generally awesome design a lot.

Buyer’s Guide

Amplifiers, subwoofers, speakers — you can hardly imagine your car audio system without this equipment. The mentioned elements are essential producers of the impressive sound in your vehicle. No matter if you do your best to achieve clean sound or earth-shattering bass, there are some typical mistakes many customers do in the pursuit of cleaner, deeper, more powerful music. Some of them are pretty obvious, but others are not so apparent. So let us get into it!

Gain Control

It is a huge mistake to use the gain control as an alternative to a volume dial. All aftermarket equipment of the kind possesses these elements. So some customers may confuse them.

In simple words, the gain control is aimed at matching the maximum undistorted level of the source unit to the same parameter but on the amplifier. This process is performed whenever you switch on your radio and turn it up to the maximum volume. Besides, this action calibrates the amplifier. This calibration plays an important role since it allows matching to different audio-producing gadgets. By that, we mean different voltage levels output by source units and radios of numerous companies. Unfortunately, even though gain control button and volume knob have completely unlike appearances, people often use both to control the volume. For instance, if the volume knob is 50% position, then this element is playing with half of the power. Some people think the same is true for the gain control. However, it is not that case. By turning the gain control too high, you can cause serious damage to your equipment. Of course, this will influence the sound quality and add some unpleasant defects into the music flow.

How do we make sure that there are no problems with the gain? If your system is installed with the help of professionals, then they use special devices like a purpose-built tool or an oscilloscope for distortion detecting. In such a way, it is not a challenge to set the gain correctly. If a customer does not have access to the previously mentioned tools, then we recommend using a voltmeter. However, note this is not a cure-all method since it is not as accurate.

Quality vs. Price

A huge mistake for any car audio improver is to use poor quality equipment. In this case, we have to remember the law of diminishing returns. In general, going from a product that costs $200 up to $300, we will notice much more of a performance increase, than if we go from a product that is $1,200 to $1,300. It is not a rule of thumb that more expensive devices are synonyms to a top-notch quality and efficiency. You do not have to spend a ton of money to get decent sound. In this day and age, you can definitely get a really nice audio system within your budget. What we can recommend is to pay attention to production of reputable brands. For instance, we consider Kicker 1000 watt amp best buy. Other companies like JL Audio, Kenwood, Rockville, etc. have already become generic names in the industry.


When choosing an amplifier, there is nothing weird about the customer’s desire to buy the most powerful solution. However, each audio system consists of several elements, so all of them should be matchable to produce the best quality sound.

People that are new to car audio prefer focusing on the max wattage output for an amplifier. We are here to tell that this parameter is more of an advertisement method, and that is it. In order to compare devices of the kind truly, we suggest you to look at the watts RMS rating.


Of course, there are other features of amplifiers that you should definitely consider when making your final choice. Impedance is a parameter that lots of newcomers often have no idea about. In audio, impedance is the amount of resistance or position to an audio signal. This rating is measured in ohms. It could be compared to a large water tank with a smaller outlet hole at the bottom. The size of the hole determines the level of resistance or opposition to the water flow.

In our technical case, impedance is generally reduced down to two types: low and high. Speakers can refer to each of them. You can search for more detailed information on the Internet. What is necessary to remember is to know how to match this rating on your devices.

  1. The impedance on your speakers should equal this parameter on your amplifier. For instance, there are lots of speakers with the 4 ohms impedance. Therefore, your amplifier should have the same level or be available to customer’s adjustments.

How can customers find out the impedance rating? It is as easy as ABC: manufacturers provide this data in supporting documents to the product.

Wiring Issue

The installation process can become a challenge even for pro amplifiers users. However, it is really important to avoid any wire issues. Of course, it is necessary to check once or even twice that everything is wired properly. There is a simple rule for newcomers. In simplest words, positive wires should be connected to the positive terminals, and negative ones to the negative terminals.

Music Quality

No matter how advanced your audio system is, you will lack power and performance when using low-quality music files. Customers usually focus on purchasing the best devices possible and completely forget about this important influencer.

Nowadays, there are lots of music formats. Each of them is suitable for its particular case. When talking about your car audio system, it is worth to choose 320 kilobits per second files. A slightly better alternative is to listen to the music of FLAC format.

Why is this parameter so important? There is no sense to spend hundreds or even thousands of dollars to upgrade and improve your car audio system, and then to spoil everything with low-quality music.


  1. Are amplifiers, stereo amplifiers, and AV receivers the same thing?

Briefly speaking, all these devices belong to one type of product. Their main function is to amplify signals. However, amplifiers are the simplest among them. They are dedicated for cars or other vehicles only. If you want to connect your speakers and subwoofers to sound better together or separately, then go for the amplifiers without any doubts.

Stereo amplifiers and AV receivers are all-in-one-box devices. While stereo amps consist of amplifiers and preamps, AV receivers also include tuners. In simple words, both of the devices can upgrade your home stereo system. But AV receivers will be a better solution when it comes to correcting video signals of the latest formats.

  1. What is an amplifier and why is it so necessary for car audio systems?

An amplifier essentially does what it is called. It takes signal from a source unit, which is typically a low-voltage signal. Then a device of the kind amplifiers that signal to a much greater one. Well, it is hard to say specifically what the output would be since amplifiers have different watts RMS ratings at different ohms. But what they do is powering your speakers and subwoofers. Without an amplifier, you can hardly match all the elements of your car audio system to sound brilliantly. While some speakers can run off low power just from your car stereo alone, amplifying your speakers will really bring out their full potential and make your system shine.

  1. Do amplifiers sound in a different or in the same way?

Of course, each particular situation will make an amplifier produce somewhat unique sound. Even if all the customers choose the single amplifier for their systems, they still have different speakers and subwoofers with their specific parameters. For instance, some speakers are harder to drive than others. A lot depends on the impedance balance as well. Overall, the more accurate you will be able to match your equipment to each other, the better sound you will get as a result. Sometimes, even low-budget devices are three times more impressive in sound amplifying than super up-market tools, if the latter are installed improperly.


All in all, the choice of an amplifier for your car audio system can easily turn out to be a heavy headache. It is especially true for those cases when customers believe in luck and do little efforts to select the best option. Remember once and forever: the price is not the main parameter for the choice of a highly-qualitative product.

In this article, we have done our best and everything possible and impossible to select useful tips and recommendations in one place. Here, you can get acquainted with our top-5 best 1000 watt car amps. Their suitability and affordability can impress even the most demanding consumers.

If you are an audiophile and wish to make your car audio system sound deep and fresh at the same time, then do not wait a single moment. Just check out our list of the premium products. Do not miss this opportunity. Enjoy the feeling of the music and not the casual listening to it with one of our amplifiers!
