Hertz Marine Venezia V4
Ch: 4 - 3 - 2 | 1160 W
The Venezia V4 is the most powerful four-channel Hertz marine amplifier to date, delivering 160 W x 4 (4Ω) and 580 W x 2 bridged (4Ω). Hertz Advanced Class D technology maximises efficiency and output while minimising heat and electromagnetic radiation, contributing to Hi-Res certified sound quality. High-powered channels with bridging capability provide the output levels required in demanding marine environments. The V4 is engineered and tested for marine use — UV, salt-fog, vibrations, high/low temperature and thermal shock — and holds IPX2 certification. Safe-Lock input, output and power connections simplify installation and improve long-term durability. Cooling is handled by a fanless convection system integrated into the cast heat-sink chassis. Balanced fully-differential input circuitry rejects electromagnetic noise and interference. The preamp filter section is powerful and flexible, and the amplifier is fully protected by auto-resetting short-circuit, overload and thermal protections.

Frequently Asked Questions
Q: Can the Venezia V4 run a subwoofer?
A: Yes. It can run in three-channel mode with 160 W x 2 at 4 ohms plus 580 W x 1 bridged at 4 ohms for a subwoofer, or in two-channel mode at 580 W x 2 into 4 ohms.
Q: What is the minimum impedance of the Venezia V4?
A: 2 ohms per channel in four-channel mode, and 4 ohms per bridged channel.
Q: Is the Venezia waterproof?
A: It is engineered and tested for marine use (UV, salt fog, vibration, high and low temperature and thermal shock) and carries IPX2 certification, which covers dripping water. It is not rated for submersion, so mount it in a protected location on the boat.
