Series: Fight
Meet the Fight 350.4 — the flagship four-channel of the Fight series, built for those who want their front stage to hit as hard as their bass. Stable down to 2 Ohm per channel, it delivers a massive 4 x 500W RMS at 2 Ohm — and in bridged mode it transforms into a full-scale powerhouse pushing 2 x 1000W into 4 Ohm.
Flexibility is where the Fight 350.4 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. A wide frequency response and generous input sensitivity range make it a seamless match for any head unit.
Still compact enough for stealth installs, yet powerful enough to anchor a competition-grade front stage — the Fight 350.4 is the heavyweight champion of the lineup.
