• 2-ohm stability to drive lower impedance configurations and maximize output
• High-pass crossover adjustable from 50 Hz to 5 kHz for delicate mids and highs
• Low-pass crossover adjustable from 50 Hz to 400 Hz for tight, impactful bass
• 0–18 dB bass boost with phase shift control for tailored tonal balance
• MOSFET power supply for efficient, stable performance
• Bass knob included for on-dash adjustment and quick tuning
• Excellent signal clarity with a reported 95 dB SNR and a wide 20 Hz–35 kHz range

Build, tuning, and real-world use

Beyond raw power, the XTR1000.4 offers precise control to shape your listening experience. The wide frequency response and strong signal-to-noise ratio help reveal details in music and dialogue, while the crossover options let you assign channels to front, rear, or subs with confidence. In a typical setup, you might pair this amplifier with a multi-speaker arrangement—two midrange/two tweeters or two full-range channels on the front and two bass-focused channels for subs—then fine-tune for balance using the bass knob and phase control.

Designed with installation in mind, the compact form sits neatly on a custom rack or under a seat. The Korea-made craftsmanship lends a sense of solid engineering behind the performance, aligning with Orion’s long-standing emphasis on punchy dynamics and reliable operation in real-world driving conditions.
