AudioWinner E46.4A 4-in 6-out Class AB DSP Car Amplifier

E46.4A 4-In 6-Out Class AB DSP Car Amplifier

AudioWinner E46.4A combines four-channel Class AB amplification and six-channel DSP output in a compact enclosure. It is designed for factory and aftermarket car audio upgrades that need built-in speaker power, professional signal processing and optional system expansion through RCA outputs.

Four high-level inputs support integration with compatible factory head units. Optical input, Bluetooth 5.4, built-in USB audio and USB disk playback provide multiple source options, while PC and mobile tuning give installers detailed control over the audio system.

Why Choose E46.4A

• Combine four-channel amplification and DSP processing in one compact unit

• Deliver 4 × 25W at 4Ω or 4 × 50W at 2Ω

• Retain compatible factory head units through four high-level inputs

• Add external amplifiers through six independently tunable RCA outputs

• Add Bluetooth 5.4, optical, USB audio and USB disk playback

• Tune EQ, crossover, delay, phase and presets through PC or mobile apps

• Reduce installation space compared with separate DSP and amplifier units

Connectivity and System Integration

E46.4A accepts four high-level input channels or two RCA input channels for connection to compatible factory and aftermarket head units. Optical input, Bluetooth 5.4, built-in USB audio and USB disk playback provide additional source options.

Four amplified high-level outputs can drive compatible speakers directly. Six RCA outputs allow installers to add external amplifiers or expand the system beyond the four built-in amplifier channels.

The REM input and output allow E46.4A and connected equipment to switch on as part of the same audio system.

Compact Class AB Amplification with DSP Expansion

E46.4A provides four built-in Class AB amplifier channels for direct speaker connection while retaining six RCA outputs for external-amplifier expansion.

This configuration is suitable for compact upgrades where the main speakers need moderate built-in power but additional DSP-controlled outputs may be required for a subwoofer amplifier or other system expansion.

At 4Ω, E46.4A delivers 4 × 25W RMS. At 2Ω, it delivers 4 × 50W RMS. Confirm the speaker impedance and wiring configuration before installation.

Professional DSP Tuning and Control

Each output channel can be configured according to the connected speaker and amplifier arrangement. E46.4A provides:

• 31-band equalization

• Up to 15ms time alignment

• Crossover adjustment from 20Hz to 20kHz

• Butterworth, Bessel and Linkwitz-Riley filters

• Filter slopes from 6 to 48dB/octave

• Adjustable Q values from 0.5 to 9

• EQ gain from −18dB to +12dB

• 0° and 180° phase selection

• Ten user presets

Tuning is available through Windows PC software and supported Android and iOS apps. A compatible wired controller can be added for convenient volume, source and preset control.

E46.4A uses a Cirrus Logic Smart HiFi 3-core DSP platform with CS47L35 and CS4344 audio components. Its four-channel Class AB amplifier stage uses the TDA7851 amplifier platform.
