- Key Specs
- Continuous Watts x Channel @ Ohms: 50 Watts x 6 @ 4 Ohm
- Amplifier Class: AB (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)

- Audio
- Number Of Channels: 6
- Minimum Frequency Response: 10 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 45 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)

Clarion amplifiers feature uncompromising resistance to magnetic noise, thereby minimizing distortion, as well as high quality terminals to offer low electrical and contact resistance. Easy subwoofer system configuration is possible with the embedded high pass filters. The result is high quality sound you can enjoy in a variety of systems. By utilizing corrosion resistant RCA and Connectors, XC series amplifiers offer improved durability and reliability in harsh environments. The XC series amplifiers are true marine amplifiers with efficient aluminum heatsinks and locking power terminals for the harsh marine conditions. There’ s only one way for Clarion’ s main units to deliver unyielding power output and linearity: MOS-FET amplification, or Metal Oxide Semiconductor Field Effect Transistor amplification. Smaller and more efficient than conventional power supplies, a MOS-FET amplification circuit delivers power with less distortion and zero On/Off switching noise. This means you can crank up the volume or set it to easy listening. Either way, your sound will be crystal clear.
