Overview

Rainbow EL-AP300D 6-Channel DSP Amplifier – 4x45W RMS

The Rainbow EL-AP300D combines a six-channel digital signal processor with a four-channel Class D car amplifier in a compact chassis. It is designed to upgrade factory audio systems that require precise tuning, flexible signal integration, and efficient amplification without installing several separate components. Four amplified channels deliver 45 watts RMS each at 4 ohms, while six RCA pre-outs support additional external amplifiers for more advanced configurations. High-level and low-level inputs enable integration with factory and aftermarket head units, and automatic signal sensing simplifies connection to compatible OEM systems. Built-in Bluetooth, comprehensive DSP controls and multiple saved presets make the EL-AP300D a versatile foundation for a professionally tuned car audio system.

Key Features

• Six-Channel Digital Signal Processor: Provides independent control over six output channels for building and tuning multi-speaker car audio systems.
• Four-Channel Class D Amplifier: Delivers efficient amplification in a compact enclosure, reducing the need for a separate four-channel power amplifier.
• 4x70W RMS at 4 Ohms: Supplies continuous power suitable for driving compatible component speakers, coaxial speakers or an actively configured front stage.
• Six RCA Pre-Amplifier Outputs: Allow external amplifiers to be added for subwoofers or additional speaker channels as the system expands.
• Flexible Factory Integration: Four high-level inputs with automatic turn-on support connection to compatible factory head units without RCA outputs.
• Low-Level RCA Inputs: Two RCA input channels provide a direct signal connection for compatible aftermarket car stereos and other audio sources.
• 31-Band Parametric Equalisation: Offers detailed frequency adjustment on each DSP channel to compensate for speaker placement and vehicle acoustics.
• Independent Crossover Control: Supports Linkwitz-Riley, Butterworth and Bessel filters with adjustable crossover points and slopes for precise driver management.
• Time Alignment and Phase Adjustment: Corrects differences in speaker distance and polarity to help create a more focused sound stage from the listening position.
• Built-In Bluetooth Connectivity: Supports wireless audio streaming and mobile device access without requiring a separate Bluetooth module.
• Six User Presets: Stores multiple tuning profiles for different listeners, music preferences or system configurations.
• Compact Installation Footprint: Measures 178 x 150 x 40mm, allowing installation in confined areas where larger processors and amplifiers may not fit.

Ideal For

• Upgrading factory car audio systems
• Active two-way front speaker installations
• Systems requiring an external subwoofer amplifier
• Vehicles with limited amplifier mounting space
• Professional DSP tuning and sound-stage correction
• Factory head units without RCA outputs

The Rainbow EL-AP300D provides amplification, signal integration and detailed audio processing within one compact unit. Its four powered channels can operate compatible speakers directly, while six processed RCA outputs allow the system to incorporate additional amplifiers when required. Comprehensive equalisation, crossover, time-alignment and phase controls give installers the tools needed to address challenging vehicle acoustics. For factory audio upgrades and compact aftermarket systems, the EL-AP300D offers a flexible platform that can improve tonal balance, speaker integration and sound-stage positioning.
