If you’re building a serious sound system that demands clean, powerful, and full-spectrum audio output, the Orion XTRPRO4.2K is the amplifier you’ve been waiting for. As the most powerful 4-channel model in the XTRPRO lineup, it delivers up to 520 watts per channel at 1 ohm, giving you the headroom and flexibility needed for 3-way active systems, multi-driver doors, or even low-end reinforcement.
This amp is powered by Orion’s exclusive IntelliTech full-range architecture, which gives you advanced signal control, thermal protection, and tuning flexibility—all wrapped in a rugged chassis that’s still compact enough for tight installs. Designed for both pros and enthusiasts, the XTRPRO4.2K combines raw power, intelligent design, and unmatched versatility, allowing it to adapt to whatever your build demands.
