Series: Fight
Meet the Fight 250.4 — the golden middle of the Fight series four-channel lineup, delivering the perfect balance of power, refinement, and size. Stable down to 2 Ohm per channel, it drives your full front stage with clean, confident power — and when it's time to bring in the bass, bridged mode turns it into a true sub driver pushing 2 x 660W into 4 Ohm.
Flexibility is where the Fight 250.4 shines. With fully adjustable High Pass and Low Pass filters that can work simultaneously, you get real bandpass capability on board — perfect for dialing in midbass drivers or building active multi-way systems without external processors. Add an impressive 94 dB signal-to-noise ratio, and every note comes through clean, detailed, and free of unwanted hiss.
Compact enough to hide under a seat, tough enough to run all day — the Fight 250.4 is the sweet spot for anyone serious about sound quality.
