Submarine Audio SA-80.4D — 320W 4-Channel Marine Class D Amplifier

WET. LOUD. DIRTY.

The Submarine Audio SA-80.4D is a compact 4-channel Class D amplifier built for powersports and marine audio systems where space is limited and reliability matters. Delivering 80 watts RMS per channel at 4Ω, the SA-80.4D provides clean, efficient power for upgrading speakers in boats, UTVs, side-by-sides, motorcycles, golf carts, and other 12V applications.

Its IPX6-rated water-resistant construction and marine-grade circuit boards are designed for demanding environments where conventional car-audio amplifiers aren’t the best choice. The compact chassis makes it easy to mount in tight locations, while the Class D design provides strong output without the size and heat of a traditional amplifier.

With both high- and low-level inputs, adjustable crossover controls, and a wide 9–16V operating range, the SA-80.4D is designed to work with everything from factory audio systems to completely custom builds.
