Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
Amplifier Key Features
Amplifiers can offer a diverse array of features. If you select more than one feature, then you will view amplifiers that have ALL features selected. These include speaker-level inputs that facilitate seamless integration with factory audio systems, Bluetooth connectivity suitable for ATV/UTV or Classic vehicle setups, built-in DSPs that provide enhanced control over your audio signal, and a host of other functionalities to explore.
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.
Series
Many brands group their products into series or lines of products to help customers know the level of quality (good, better, best for example). You can filter by series and the brand using our guided browsing.

Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Remote bass/level controller
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Amp Bluetooth Connectivity
This feature will tell you if the amplifier has the capability to connect to a Bluetooth device.

    FAQ Frequently asked questions in Discontinued 4-Channel Amplifiers

    4 Channel Amplifiers Frequently Asked Questions (FAQ)
    A 4-channel amplifier is a type of car audio amplifier that features four separate channels, each capable of powering a speaker or a pair of speakers. By distributing power across four channels, you can connect your front and rear speakers to the amplifier, significantly enhancing the overall sound quality and clarity in your car audio system. With a 4-channel amplifier, you can achieve a balanced soundstage, where the music seems to come from different directions, providing an immersive listening experience. Additionally, these amplifiers often come with adjustable crossovers and gain controls, allowing you to fine-tune the audio output for each set of speakers, optimizing the sound reproduction according to your preferences.
    Yes, many 4-channel amplifiers are bridgeable, allowing you to combine two channels to power a single speaker or subwoofer with higher output power. This bridging capability is useful if you have a pair of high-powered front speakers or a powerful subwoofer that requires more power than a single channel can provide. However, it's essential to check the amplifier's specifications and instructions to confirm its bridgeability and the recommended bridging configurations. Not all 4-channel amplifiers support bridging, and improper bridging can damage the amplifier or connected speakers. If you are unsure about bridging your 4-channel amplifier, consult the amplifier's manual or reach out to Sonic Electronix customer support for expert assistance.
    To select the right 4-channel amplifier for your speakers, consider their power handling capabilities and impedance. First, identify the RMS power rating of your front and rear speakers. The amplifier's RMS power output per channel should match or slightly exceed the RMS power rating of your speakers to ensure optimal performance without distortion. Next, check the impedance (measured in ohms) of your speakers, as well as the amplifier's minimum and maximum impedance ratings. Match the speaker impedance with the appropriate amplifier channels to prevent compatibility issues. For example, if your speakers have an impedance of 4 ohms, make sure the amplifier channels for those speakers can handle a 4-ohm load. Paying attention to these specifications ensures a seamless integration of your speakers with the 4-channel amplifier.
    Yes, a 4-channel amplifier can be used to power additional speakers, such as tweeters or coaxial speakers, in your car audio system. Beyond the front and rear speakers, a 4-channel amplifier has the flexibility to accommodate additional speaker types, provided that the total load impedance and power requirements of the amplifier's channels are within its specifications. For example, if your 4-channel amplifier has two unused channels, you can use them to power additional speakers for improved sound coverage and audio performance. Be cautious not to overload the amplifier, and ensure that the speakers' impedance and power handling align with the available channels to avoid damaging the amplifier or speakers. If you have questions about expanding your audio system with a 4-channel amplifier, seek expert advice from Sonic Electronix.
    A proper and safe installation of a 4-channel amplifier is essential for optimal performance and to prevent any electrical or mechanical issues. To ensure a successful installation, start by reading the amplifier's user manual thoroughly, as it contains specific instructions and guidelines for installation. Follow all safety precautions and use the appropriate wiring and connectors rated for the amplifier's power output. Securely mount the amplifier in a well-ventilated area, away from heat sources, and avoid placing it on carpeted surfaces. Route and secure all cables carefully to avoid interference and potential hazards. Double-check all connections to ensure they are tight and secure. If you are not confident in installing the amplifier yourself, consider seeking professional installation services to ensure a safe and expertly done installation that optimizes the performance of your 4-channel amplifier and car audio system.
