This amp is a good option if you’re installing audio in a boat, jet‑ski or other marine environment and you need a 4‑channel amplifier that can handle front & rear speakers (or four zones) while resisting exposure to moisture/salt. Its moderate per‑channel power (≈100–110 W at 2Ω) makes it better suited for full‑range speakers rather than big subwoofer duty. The bridging mode gives two channels ~185 W @4Ω for higher power on two speakers if needed.
