When a vehicle audio system needs strong output across multiple speakers but space, power efficiency, and clean signal control are still important, a compact Class D amplifier can provide a practical solution. The Hertz VENEZIA V4 is designed for this type of multi-channel audio installation, with four amplified channels and flexible power configurations for different speaker loads.
Hertz VENEZIA V4, 1160 W D-class 4 Channel Audio Amplifier
The Hertz VENEZIA V4 is a four-channel Class D audio amplifier designed to deliver high power while maintaining efficient operation. Its 1160 W total RMS capability allows it to drive multiple speakers with substantial output, making it suitable for systems where a single amplifier needs to handle several channels.
The amplifier accepts low-level PRE IN signals and provides adjustable crossover control for configuring the audio system according to the connected speakers. Its filtering options include high-pass and low-pass operation, while the B channel also provides adjustable bass boost. This gives installers more control over how different parts of the audio system are powered and balanced.
The VENEZIA V4 supports several output configurations, including four-channel operation, three-channel combinations, and two-channel operation. This flexibility allows the amplifier to be matched with different speaker arrangements and impedance requirements instead of limiting the installation to one fixed configuration.
Its Class D design provides an efficiency rating of 87, helping the amplifier produce high output without relying on the same operating approach as a traditional amplifier design. Features such as a 102 dB signal-to-noise ratio, 130 damping factor, and low THD support clean and controlled audio reproduction when the amplifier is correctly integrated with the rest of the system.
With a 9 to 16 VDC power supply range, remote input control, adjustable crossover functions, and multiple speaker-load configurations, the Hertz VENEZIA V4 is suited to vehicle audio installations that require high-power multi-channel amplification. Its compact dimensions also make it easier to integrate into installations where available mounting space is limited.
