Amplified Class-D 4-Channel Power Amplifier (RMS 100W × 4)

Power your entire vehicle audio system with the Amplified Class-D 4-Channel Car Audio Power Amplifier (RMS 100W × 4CH). Engineered with high-efficiency Class-D switching topology, this compact powerhouse delivers substantial, clean continuous power while generating minimal heat and drawing significantly less current than traditional Class-AB amplifiers.

Built with an ultra-compact, extruded aluminum chassis, this 4-channel amplifier installs easily into tight vehicle spaces—such as under front seats, behind rear bakkie seats, or inside boot side-panels—while driving full-range door speakers, component sets, or bridged subwoofers with low distortion and dynamic impact.

Key Features & Benefits:

• High-Efficiency Class-D Topology: Operates at over 80–90% electrical efficiency, producing higher sustained wattage output with minimal heat generation, preserving vehicle electrical systems and preventing thermal throttling.
• Continuous True RMS Output: Delivers a conservative 100W RMS per channel into 4 Ohms (or up to 150W RMS × 4 into 2 Ohms), providing clean headroom to prevent speaker clipping and harsh distortion at elevated listening levels.
• Flexible 4-Channel / 3-Channel / 2-Channel Bridging: Run in standard 4-channel mode for front and rear door speakers, or bridge channels 3 and 4 to power a subwoofer enclosure while channels 1 and 2 run the front cabin speakers.
• Comprehensive Precision Crossover Controls: Features independent variable High-Pass Filters (HPF) and Low-Pass Filters (LPF) alongside adjustable input sensitivity (gain) and bass boost controls to tailor frequency response to your vehicle acoustics.
• Ultra-Compact Space-Saving Profile: Small footprint enables discreet, hidden installations beneath seats, within center consoles, or behind commercial vehicle trim panels.
• Multi-Stage Protection Circuitry: Advanced onboard safety circuits safeguard the amplifier and speakers against thermal overheating, direct speaker short circuits, reverse polarity, and voltage overloads.
• High-Level & Low-Level Inputs: Supports low-level RCA pre-outs from aftermarket head units as well as speaker-level inputs for straightforward integration with factory OEM radios.

Ideal Applications:

• Full-Cabin Speaker Amplification: Drives premium front component speaker splits and rear coaxial speakers with dynamic clarity and vocal punch.
• Hybrid 3-Channel 2.1 Systems: Configured as a complete single-amplifier solution running front door speakers on channels 1 & 2 while bridging channels 3 & 4 to drive a 4-ohm sub.
• Space-Restricted Vehicles: Ideal for single-cab and double-cab bakkies, compact hatchbacks, and classic vehicles where boot or interior mounting space is limited.
