GALEFORCE AUDIO K1200.4 4-CHANNEL CLASS-D AMPLIFIER
WHY THIS ONE MAKES SENSE
The K1200.4 is built for high-output multi-speaker systems where the amplifier has to do more than post a big wattage number. GaleForce rates it at 190W × 4 at 4Ω, 300W × 4 at 2Ω, or 570W × 2 bridged at 4Ω, with all three ratings dyno-certified at 12.6V. Its wide onboard high-pass and low-pass controls also make it useful for dedicated midrange systems that need bandpass crossover control.
HOW IT FITS A G3 SYSTEM
A single 4-ohm G3 on each channel sees the K1200.4's published 190W-per-channel 4-ohm rating, which is a close match to the G3's 200W RMS rating. Two 4-ohm G3s wired in parallel on one channel create a 2-ohm load; the amplifier is rated at 300W on that channel, so two identical speakers would share roughly 150W each. Two 8-ohm G3s in parallel create a 4-ohm load and would share the channel's 190W, roughly 95W each.
Those are system-design examples, not a reason to chase the lowest possible impedance. Speaker count, final load, amplifier power, wiring, and crossover settings all have to be planned together.
CROSSOVER ADVANTAGE
The K1200.4 provides a 20 Hz–8 kHz high-pass range and a 50 Hz–8 kHz low-pass range. Used together, those controls can band-limit a dedicated midrange such as the G3. A DSP gives more precision, but the onboard network is much more useful than a basic fixed-range crossover when building a pro-audio-style system.
IMPORTANT FREQUENCY-RANGE LIMITATION
GaleForce publishes the amplifier's frequency response as 20 Hz–8 kHz. That is a strong fit for midrange duty, but it is not a conventional 20 kHz full-bandwidth specification. If the system uses a T25 Super Tweeter to its published 20 kHz upper range, plan the high-frequency amplification separately rather than assuming the K1200.4 covers that entire band.

AMPLIFIER SYSTEM FIT
Where this fits in the build
An amplifier should be chosen around the channels, load, speaker or subwoofer plan, available electrical support and how hard the system needs to play.
Plan aroundMatch usable channels and power to the actual speakers and load.
Match itPlan signal processing and gain structure before chasing wattage.
Finish itHigher output may require charging, battery and wiring upgrades.
