The Kicker KXMA1200.2 puts out 600W per channel at 2-ohm, or 300W per channel at 4-ohm, across just two channels. That's double the per-channel output of the KXMA500.4's 125W (2-ohm) we've reviewed separately, on an amp with half the channel count. At $649.99, this isn't built for a typical stereo speaker pair, it's built for two subwoofers or a pair of speakers that can actually use that much power.
Two channels at this output level is a deliberate design choice, not a limitation. Concentrating power into fewer channels means each one gets genuine headroom instead of spreading the same wattage thin across four or eight outputs.
Key Takeaways
- 600W per channel at 2-ohm, 300W at 4-ohm, across 2 channels only, roughly double the KXMA500.4's per-channel rating on half the channel count.
- Same FIT2 circuitry, DSP-controlled preamp, and gain-match LED as the rest of the KXMA line.
- Gasket-sealed cover panel protects gain, crossover, and bass-boost controls from moisture.
- 1500W dynamic power headroom, the highest dynamic rating among the multi-channel KXMA amps.
- At 7.8 lbs and a 5"x11"x17" footprint, it's a compact chassis for the power density it delivers.
Why Fewer Channels at Higher Power Makes Sense
A 4-channel or 8-channel amp splits its total output across more speakers, which works well for a full-range system with several small speakers. The KXMA1200.2 takes the opposite approach: two channels, each capable of real subwoofer-level output, for builds where you specifically want two high-power channels rather than several modest ones. Running two subwoofers off separate channels of this amp, instead of bridging a multi-channel amp's outputs together, keeps each sub on its own dedicated, fully-rated channel.

Feature Walkthrough
Power Output
2x600W at 2-ohm, 2x300W at 4-ohm, with 1500W of dynamic power and a 10Hz-20kHz frequency response.
KXMA Electronics
FIT2 fail-safe circuitry, a DSP-controlled preamp, and a gain-match LED indicator, the same electronics package that distinguishes the KXMA line from the standard KMA amps across every model we've covered.
Build
Black anodized aluminum chassis, top-mounted teal LED light pipe, and a gasket-sealed cover panel protecting the gain, crossover, and bass-boost controls specifically.
Amplifier-to-Speaker Matching
At 300W per channel (4-ohm), this amp significantly exceeds the power handling of most standard coaxial speakers, making it a better match for subwoofers or high-power tower speakers than a typical flush-mount speaker. Running it against a modest 60-100W RMS speaker leaves the majority of its output unused. Confirm your specific speaker or subwoofer's RMS rating before setting gain.
Who It's For
Choose the KXMA1200.2 if you're running two subwoofers on separate channels, or two speakers that specifically need 300W+ each at 4-ohm. It's the wrong amp for a standard 4-speaker system, where a 4-channel amp splits power more appropriately across more outputs.
Honest Cons
Only 2 channels. If your system needs to power more than two speakers or subs, this isn't the right channel count regardless of per-channel output.
Significant overkill for standard speakers. Match this amp to subwoofers or genuinely high-power speakers, not a typical coaxial pair.
No numbered IP rating published, despite the ABYC/NMMA-compliant connections.
Frequently Asked Questions
Can I use this to power four regular speakers?
Only two channels are available, so you'd need to bridge or split channels in a way that isn't how this amp is designed to be used. A 4-channel amp is the more appropriate choice for four standard speakers.
Is 600W per channel too much for any subwoofer?
Match the amp's output to your specific subwoofer's RMS rating; running significantly more power than a sub is rated for risks damage. Confirm before setting gain.
How does this compare to the KMA600.4?
The KMA600.4 spreads 150W RMS across 4 channels at 4-ohm; the KXMA1200.2 concentrates 300W RMS into just 2 channels at the same impedance, a genuinely different power distribution, not just a bigger number.
Does it have the same gasket-sealed controls as other KXMA amps?
Yes — identical control protection to the rest of the KXMA line.
Bottom Line
The KXMA1200.2 is built for two channels that each need serious power, not a compromise on channel count. Choose it specifically for dual subwoofers or high-power speakers; a multi-channel amp still makes more sense for a standard multi-speaker system.
