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 Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
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 5-Channel, 6-Channel & 8-Channel Amplifiers

    5-Channel, 6-Channel & 8-Channel Amplifiers Frequently Asked Questions (FAQ)
    5-channel, 6-channel, and 8-channel amplifiers are multi-channel car audio amplifiers that provide various configuration options for powering speakers and subwoofers in a vehicle's audio system. The primary advantage of these amplifiers is their versatility and space-saving design, as they consolidate the amplification of multiple speakers and subwoofers into a single unit. A 5-channel amplifier typically powers four speakers and a subwoofer, while a 6-channel amplifier can accommodate six speakers or four speakers and a pair of subwoofers. An 8-channel amplifier is even more flexible, allowing for various configurations to suit complex audio setups. These amplifiers simplify installation and reduce the need for multiple separate amplifiers, making them an ideal choice for those seeking efficient use of space and improved audio performance.
    Yes, many 5-channel, 6-channel, and 8-channel amplifiers are bridgeable, allowing you to combine channels to increase the power output for your subwoofer. Bridging channels allows you to deliver more power to a single speaker or subwoofer, enhancing its performance and bass output. However, it's essential to check the amplifier's specifications and instructions to ensure it supports bridging and to determine the recommended bridging configurations. Not all multi-channel amplifiers have bridgeable capabilities, and improper bridging can lead to damage to the amplifier or connected speakers. If you're considering bridging your amplifier, consult the user manual or seek advice from Sonic Electronix's customer support for assistance.
    Yes, that's one of the significant advantages of these multi-channel amplifiers. A 5-channel amplifier, for example, typically provides enough channels to power four speakers (front and rear) and a subwoofer. Similarly, a 6-channel amplifier can accommodate six speakers or a combination of speakers and subwoofers. The 8-channel amplifier offers even more flexibility, allowing various configurations to power a comprehensive audio system. Using a multi-channel amplifier simplifies the wiring and installation process, as it consolidates the amplification of multiple components into one unit. However, ensure that the amplifier's power ratings and impedance compatibility match your speakers and subwoofers to avoid any issues related to underpowering or overpowering the connected components.
    The ideal location to mount a multi-channel amplifier is in a well-ventilated and secure area within the vehicle's interior. It's essential to consider the amplifier's dimensions and select a suitable location that allows for proper air circulation to prevent overheating. Common mounting locations include the trunk, under a seat, or in the cargo area, as long as these locations meet the amplifier's space requirements and ensure adequate ventilation. Avoid placing the amplifier near heat sources, such as the vehicle's exhaust system or engine bay, as excessive heat can negatively impact the amplifier's performance and reliability. Additionally, secure the amplifier properly to prevent vibrations and ensure it stays in place during vehicle movement. Proper installation and placement contribute to the amplifier's longevity and optimize its audio performance.
    To determine the power requirements and compatibility, consider the RMS power rating and impedance (measured in ohms) of your speakers and subwoofers. The RMS power rating of your speakers should match or slightly exceed the RMS power output per channel of the amplifier to ensure clear and distortion-free audio reproduction. Additionally, check the impedance specifications of your speakers and subwoofers, as well as the amplifier's minimum and maximum impedance ratings. Match the impedance of your speakers and subwoofers with the appropriate amplifier channels to avoid any compatibility issues. For example, if your speakers have an impedance of 4 ohms, ensure the amplifier channels for those speakers can handle a 4-ohm load. Proper matching of power and impedance ensures an efficient and safe operation of the multi-channel amplifier and provides an enhanced listening experience. If you need assistance in selecting the right amplifier for your speakers and subwoofers, Sonic Electronix's knowledgeable staff is available to help guide you through the process.
