KICKER Car Amplifier Guide: CXA, KEY & LX

Choose what you need to power first: a subwoofer, full-range speakers, or speakers and a subwoofer together. Then compare the exact model's RMS output at your final speaker load, installation space and electrical requirements.

CXA mono amps for subwoofer systems

Compare mono subwoofer amplification across the CXA range. The model's headline wattage is not its output at every impedance; confirm the published rating at your final wired load.

CXA multichannel system options

CXA360.4 is a four-channel amplifier. CXA660.5 adds a dedicated subwoofer channel to its four full-range channels. Check per-channel output and the supported loads for your planned system.

KEY smart amplifier options

KEY200.4 is a four-channel smart amplifier for full-range speakers. KEY500.1 is a mono smart subwoofer amplifier. Their DSP functions and system roles differ; check the exact installation and setup requirements.

LX mono subwoofer amps

Compare LX mono amplification for your subwoofer build. Plan power delivery, wiring, cooling and the final speaker load before choosing the amplifier.

LX multichannel system amps

Compare four-, five- and seven-channel LX layouts against the number and type of speakers in your system. Check the exact channel configuration and ratings before ordering.

An amplifier choice does not establish vehicle fit or a complete installation. Confirm source integration, speaker impedance, power wiring, fuse requirements and mounting space. Ask MCOR through chat if you need help choosing.
