Wiring Wizard & Port Calculator

Use our wiring assistant for easy speaker and subwoofer connections! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The datasheet shows you which connection each amplifier is designed for!

Our port calculator shows you the tuning characteristics of your enclosure! The net volume is always particularly important here; calculate the subwoofer’s actual resonant chamber volume beforehand to get the correct result. The net volume is calculated by subtracting all dead spaces and is crucial for enclosure design.

Bedienungsanleitung

The SounDigital 400.4 EVO 6.0 was developed for high-end car audio systems where installation space is limited, without having to compromise on power or sound quality. Despite its extremely compact design, the digital 4-channel amplifier delivers up to 4 x 100 watts RMS into 2 ohms or 2 x 200 watts RMS in bridge mode, making it ideal for front and rear speakers or for powering a compact subwoofer.

The EVO 6.0 series features modern Class D technology that offers high efficiency, low power consumption, and clean signal processing. The result is a dynamic, precise sound with high detail and excellent control over the connected speakers. Thanks to the built-in high-pass and low-pass filters, the system can be optimally adapted to different speaker configurations.

With its rugged aluminum housing, high-quality connectors, and compact design, the 400.4 EVO 6.0 is ideal for both hidden installations and demanding OEM retrofits. Whether used as a high-performance power amplifier for a premium front-end system or as a versatile solution for complete speaker systems, this amplifier combines high power output with maximum ease of installation.

Frequently asked questions about the SounDigital 400.4 EVO 6.0 amplifier

What is the power output of the SounDigital 400.4 EVO at 2 ohms?

The amplifier delivers 2 x 200 watts RMS at 4 ohms in bridged mode. This allows you to drive high-power subwoofers or connect multiple speakers per channel.

What fuses does the 400.4 EVO 6.0 require?

With a maximum current draw of 20A, a 25A fuse is recommended near the battery. The built-in protection circuit also prevents damage caused by overloading or short circuits.

How many minutes does it take for the amplifier to warm up when in use?

Thanks to the efficient EVO 6.0 technology, the housing remains only slightly warm even after 30–45 minutes of continuous operation at high volume. The compact design does not impair heat dissipation.

Can I fit the SounDigital 400.4 under the seat?

Yes, its extremely compact dimensions of 90 x 178 x 50 mm make it easy to install under vehicle seats. Ensure there is adequate ventilation, leaving a gap of at least 5 cm between the unit and other components.

What is included with the 400.4 EVO?

The amplifier comes with fixing screws, a multilingual user manual and protective covers for the connections. Cables and fuse holders must be purchased separately.

Is the amplifier suitable for active crossovers?

The wide frequency range of 10 Hz–20 kHz makes the 400.4 EVO ideal for active speaker systems. You can easily connect external crossovers or DSPs upstream and enjoy distortion-free signal amplification.

How long does the SounDigital last with daily use?

When installed correctly and operated within the specified parameters, the power amplifier will operate reliably for many years. Its robust construction and high-quality components guarantee a long service life, even when used intensively in a car.
