How to shop for 4-channel Amps

Sure, an amplifier will make your music a lot louder than your stereo can. But the true value of an amplifier really comes through at lower volumes. The extra power makes your music sound more clear and full-bodied, even when you also want to be able to have a conversation in the car.  

How to choose an amplifier

You’ll see a lot of options when shopping for an amplifier, and making the right choice depends on what you’re trying to do. 4-channel amplifiers offer a lot of flexibility for powering your car audio system. You can power all four of your car’s speakers, or you can use two channels to power your front speakers and the other two channels to power a subwoofer box.

If you want to fit the amp in a small, out-of-the-way space, consider getting a compact amplifier. They let you put big power where it would never fit before. They’re great in small cars.

For more details, read our car amplifier buying guide.


Popular questions customers ask

If the sound gets muddy when you turn it up, you need the added power of an amplifier. You probably know the difference in sound between your TV speakers and a home theater system. An amplifier in your vehicle can make that kind of difference. You’ll hear a bigger, fuller sound, with more detail and greater impact, especially if you’ve installed better speakers in your vehicle.

The first consideration is how many speakers you’ll be powering and how much power each speaker will handle. Once you know that, you’ll know how many amplifier channels you’ll need and how much power you’ll want.

Yes, you can, as long as you have a basic knowledge of electronics and you’re handy with tools. You’ll have to run a power wire from your vehicle’s battery back to your amp’s location, and then a ground wire from the amp to your vehicle’s chassis. It’s important to do the job correctly so you don’t damage your vehicle. Our Tech Support people can help you if any issues come up.

Check your speakers or sub to see how much power they can handle in terms of “watts RMS.” For a subwoofer, you should select an amplifier that produces approximately that much RMS power. Speakers are more forgiving, so you don’t always have to max them out, although more power always sounds better.

The easy answer is “one speaker per channel.” You’ll need two channels to power a pair of speakers, four channels to power your front and rear speakers, or one channel to power a subwoofer. There are plenty of exceptions to this rule, so contact an Advisor to get the best advice for your situation.

Car amplifiers come in different types depending on the number of audio channels:

  • The 2-channel amplifiers accept either a subwoofer or a pair of speakers. Often, most models of such car amplifiers support a low-impedance load (starting from 2 ohms), while some work in a bridge (positive for a subwoofer).
  • The 4-channel amplifiers are 2 2-channel amplifiers in one housing, which most often have one power supply, which increases their power. Plus, there are additional features.
  • The 5-channel amplifiers have all the features of a 4-channel amplifier, but with a separate subwoofer output (channel).
  • Amplifiers with processors to help refine the sound and make it clearer.
  • The monoblocs are bass single amplifiers with very high power (nominally from 100 watts), also capable of loading from 1 ohm (depending on the model).
Monoblocs

Monoblocks at the moment of development car audio are a single-channel system. A single-channel bass amplifier is a monoblock. At the moment, single-channel systems are not as popular as modified relatives with a large number of channels. The subwoofer amplifier is not an ordinary power amplifier, but the amplifier unit itself and other specialized devices. For example, the bass boost that is included in the monoblock design is only adjustable, that is, you yourself adjust the bass height. In bass amplifiers, the sound that is at the input and at the output is analog.

Another difference between monoblocks and all other amplifiers is their work with a filter their work with a low-pass filter. It is also impossible not to note the ability of monoblocks to operate at a load of 1 ohm, and at the same time develop even more impressive power. The monoblocks let you hear the bass you want to hear. Monoblocks are also single-channel subwoofers, which, thanks to their high power, are designed to muffle the low frequencies of extraneous car sounds that interfere with enjoying music in the car. Most often, subwoofers are installed on the front of the car in order to fill the entire area of ​​\u200b\u200bthe car with sound.

2-channel amplifiers

The 2-channel amplifiers are considered the most common among all types of audio amplifiers. The range of two-channel amplifiers themselves is also large. Why do people choose two-channel? Everything is very simple, because this is the “golden mean”. For some drivers, more channels are completely unnecessary, because they are limited to two-channel amplifiers, maybe with a connection to a subwoofer, and due to the large power reserve, monoblocks are not required at all under these conditions. On the other hand, if in the future you are going to purchase amplifiers with a large number of channels, and at the moment there is only enough money for a 2-channel, then do not despair, since these models are more versatile and flexible. In the future, you will need to purchase only the necessary components and mount them in an existing system. For those who want to choose powerful car audio, you need to carefully approach this parameter, since this question is very relative. Minimum power of the amplifier should be at least 60 watts, if more, then better. But do not forget that with high power amplifiers, crosstalk will decrease. And do not forget that as the number of connected components increases, the “transparency of sound” decreases.

4-channel amplifiers

4-channel amplifiers are less popular, but still in demand. A four-channel amplifier should have low-pass filters (LPF, LPF), as well as high-pass filters (HPF, HPF), which will allow the amplifier to be used according to the “subwoofer + front” scheme. You will like the option from the “price-quality” side. It is better to choose a subwoofer that, when switching from a four-ohm to a two-ohm load, will increase the power by 50%. It is desirable to have a remote level control. When upgrading any standard systems, high-level inputs are only welcome. Also, the circuit for automatically turning on your amplifier will not be superfluous. In any case, a four-channel will allow, in addition to greater sound, to achieve better sound quality, compensating for sound imperfections and smoothing out peaks.

Amplifiers with processors

Amplifiers with processors have a lot of both supporters and opponents, since the very question of the presence of a processor in the car audio system is very controversial. The
DSP is a Digital Signal Processor that processes the music signal and also fine tunes the sound fields. In general, how to hear this “ideal” sound? Why, that’s bad luck, since it’s hard to ensure the central position of the listener in the car in relation to all the speakers. This effect can be leveled with the help of a processor, which, having received a signal in analog or digital form, processes it depending on the user’s settings, then converts it to analog form and transmits it further to external power amplifiers . There are four types of such processors.

  • All in one. This type includes head units that are equipped with built-in time delay processors. It is inexpensive, convenient and high quality. Time correction is possible, without the need to connect external remote processors. The only thing that is uncomfortable are long cables, which can affect the sound quality.
  • Station wagon. From the head unit, the signal directly enters the processor, is processed and transmitted to the amplifier. Such 9The 0570 amplifiers are easy to connect and extremely versatile. Possibly no digital signal reception. It turns out that when a digital signal is received, it will be converted to analog and at the output in the reverse order, which leads to unnecessary and lengthy conversions.
  • One among his own. All components are made by the same company. Everywhere the signal is received and sent in digital form. It is advisable to reduce the length of the cables in order to increase the sound quality. Some amplifiers have a time delay function that is designed to shorten the intervals of sound transmission through the channels.
  • Unprecedented. This type is very uncompromising. Amplifier is located in the same housing with the processor, which minimizes the distance between them and thereby increases the sound quality. The only thing is that you have to select and buy the entire set from one manufacturer within one model.

How to connect a 4-channel amplifier in a car

Let’s talk about how to properly install and connect a four-channel amplifier in a car in order to enjoy sound quality.

Installation

First of all, you need to understand how to properly install a four-channel amplifier without damaging the interior of the car and the amplifier itself. The amplifier must be easily accessible to adjust the sound of the speakers. Consider a sedan body model and where you can build an amplifier.

· Trunk

Rear seat backrest

Space under the rear, front seat

Trunk lid

Subwoofer Enclosure

The trunk is one of the most convenient places, since the amplifier needs cooling to work properly, it does not like confined spaces! You can install it on the right, on the left, to the bottom of the trunk through the podium, to make sure that nothing damages our amplifier. We securely fasten the amplifier inside, the consequences can be sad, so do not neglect this important fact.

The rear seat back is also not a bad option. Well ventilated place, easy access, does not affect the interior. Minus – with a frequently bent back, the wires break and become damaged over time.

The space under the front seat is not the best option. Cooling is poor, not aesthetically pleasing in terms of the interior and poor protection from external threats. There is not enough free space under the rear seat, which will lead to overheating of the amplifier.

The trunk lid is a bad option, you can quickly break the wires.

There is a strong vibration on the subwoofer case, the contacts will constantly loosen. As well as vibration, it has a detrimental effect on the amplifier itself.

Amplifier connection

Now let’s figure out how to connect a four-channel amplifier.

For this you will need:

1. Supply wires (+ -),

2. Wire remote,

3. fuse,

4. terminal blocks,

5. Tips,

6. RCA interconnect cable,

7. Additional insulation (corrugation).

The greater the output power, the thicker the power cable is needed – the positive wire from the battery. We select the fuse in the same way. The fuse must be located no further than 20 cm from the battery. The closer the fuse is to the battery, the safer it is in terms of fire.

We attach the mass wire (-) to the car body, you can take the “minus” not far from the place where the amplifier will be located, thereby saving the wire. In addition, you can throw one more minus from the battery onto the car body, it will not be superfluous. It is important that all joints are well cleaned for contact.

In order to output a low-level signal from the linear output of the radio to the linear input of the amplifier, we need an RCA interconnect cable (tulip). The line output on the head unit can be right, left, as well as the input on the amplifier. Do not confuse, this affects the balance setting.

An important point is that the RCA cable should not be laid in the car along with power cables, this greatly affects the background noise in the speakers! It will be correct to lay on different sides of the car.

The amplifier is switched on directly using the remote wire – it gives a plus. Turning on the radio, the amplifier turns on. This wire of a small section, usually blue, comes out of the head unit and clings to the amplifier. You need to lay it on the same side where we have the power cable.

Additional insulation (corrugation) will be required to avoid a short circuit. Do not neglect this moment, it leads to tragic consequences. Especially pay attention to those places where the wire is in contact with the car body.

Speaker connection

Now the question is how to connect the speakers to a quad amplifier to enjoy the sound from the speakers.

There are several options here: we can connect several loudspeakers both in parallel and in series. You need to know the power and impedance of both the amplifier and the speakers. The amplifier is afraid of resistance below the declared one! That is, the greater the resistance, the better for him.

If the output resistance of the amplifier is 4 ohms, then we connect the speakers so that their total value is not less than 4 ohms. Otherwise, our amplifier will heat up. The operating temperature of the output transistor is 85 degrees. Anything higher can break our amplifier.

That is, when connected in series to one channel, our speakers in total must be at least 4 ohms. You can connect two or three speakers, 2 ohms each, which in total will be equal to or more than 4 ohms – this is the correct connection, which will positively affect the sound quality. We do the same for the other three channels.

When connected in parallel (by a bridge), we hook one speaker or several to two output channels of the amplifier (we take plus from one, minus from the other).

Here you need to sum up the two channels on the amplifier, in our case it is 4 + 4 ohms = 8 ohms. That is, the speaker, or speakers, should not be less than 8 ohms. If more is good. But then again, everything should be in moderation. It makes no sense to cling to a bunch of speakers, thereby increasing the resistance, the power will not increase from this, the amplifier will work with overload.

Based on the above, now we know how many speakers can be connected to a four-channel amplifier, and how to do it correctly.

Dual coil woofer

A low-frequency speaker – a subwoofer, can be with one coil and with two. With two coils, it looks no different from the one with one. But still, there is one difference – this is a pair of additional terminals to which the wires from the amplifier fit. A speaker with one coil has 2 terminals, and with two coils – 4. Well, two coils have two independent windings. This was done for the flexibility of connecting such a speaker. So how do we connect a subwoofer with two coils?

By the same principle as they considered with conventional speakers – in series, in parallel. Another connection option is independent.

Independent – this is when each independent speaker coil is connected to a separate channel of the amplifier (right, left). This type of connection is intended for amplifiers that do not have bridging capability.

It is better to connect such a speaker in series or in parallel, since a different signal for each channel can ruin our speaker. This type of connection must necessarily be with the same signal for each speaker coil. And the signal for the right and left channels is provided to us by the recording studio, and we cannot know how our each audio recording was recorded.

Connecting two amplifiers

Now let’s figure out how to connect two four-channel amplifiers in parallel to each other.

If you are a fan of loud and high-quality music, you may need two amplifiers for a more powerful sound output.

Both amplifiers can be powered from one power cable using a splitter (tee). The main thing is not to forget about the load on the wire: the more power is needed, the larger the cross section of the positive cable should be. The minus should be taken from one place, so that there would be no interference. Remote – a wire to turn on the amplifier, we also do one for two, branch and cling.
