Hertz VENEZIA V1 24V (D class) marine power amplifier (mono).

Hertz Venezia V1 24V (D class, RMS 1260 W x 1 Ohm) marine power amplifier (mono).

Venezia V1 24V is the most-powerful mono Hertz marine amplifier ever, featuring 1260 W @ 1Ω stable! Hertz Advanced Class D technology maximizes efficiency and power while minimizing heat and electromagnetic radiation. 
Venezia V1 24V is engineered and tested for marine applications (UV, salt-fog, vibrations, high/low temperature, thermal shock) and has obtained the IPX2 certification. 
The Safe-Lock Input, Output, and Power connections streamline installation and enhance durability in the field. The fanless convection cooling system is integrated into the cast heat-sink chassis. 
The balanced fully-differential input circuitry rejects electromagnetic noise and interference. The powerful and flexible preamp filter options are far beyond most mobile amplifier capabilities. 
Last but not least, Venezia V1 24V is fully protected by short-circuit, overload, and thermal protections - with auto-resetting.
