MARTS Digital High Power 4-Channel Amplifier - 4x240W RMS @ 4 Ohm, 7200W Peak, Class AB Full Range

Take your vehicle’s sound system to the next level with the MARTS Digital MAB 480.4 Class AB 4-Channel Amplifier. Built specifically for audio enthusiasts who demand high volume without compromising acoustic precision, this full-range amplifier delivers warm, rich sound fidelity and massive power output.

Key Features & Performance Highlights

1. Audiophile-Grade Class AB Sound Quality

Unlike standard Class D amplifiers that prioritize size over warmth, the MAB 480.4 utilizes a Class AB architecture. This topology provides smooth, natural mid-ranges, crisp highs, and minimum harmonic distortion, making it ideal for driving full-range door speakers, component sets, and tweeters.  

2. Tremendous Output & Flexible Power Handling

Engineered to operate reliably across a wide voltage range (10V to 16V VDC), the amplifier pushes impressive continuous RMS power ratings:  

 \bm{4 \times 120\text{ Watts RMS}} @ 4 Ohm (\bm{14.4\text{V}})  

 \bm{4 \times 240\text{ Watts RMS}} @ 2 Ohm (\bm{14.4\text{V}})  

 7200 Watts Dynamic Peak Power for handling transient peaks with headroom to spare.  

3. Full Acoustic Control

Tailor every channel precisely to match your audio setup:

 Selectable Crossover Control (HPF / FULL / LPF): High-Pass, Low-Pass, and Full-Range filters allow seamless integration with door speakers, midrange drivers, or subwoofers.  

 Ultra-Wide Frequency Response (\bm{10\text{Hz}} – \bm{40\text{kHz}}): Delivers deep sub-bass extension as well as ultra-high frequency detail.  

 Low-Level RCA Input Sensitivity (\bm{8\text{V}} – \bm{0.2\text{mV}}): Compatible with virtually any aftermarket head unit or line output converter (LOC).  

4. Advanced Built-In Safety Protection

Designed for long-lasting performance and peace of mind:

 4-Way Protection Circuitry: Integrated protection against Thermal Overload, High/Low Voltage, Speaker Shorts, and DC Offset.  

 LED Status Indicators: Visual diagnostic lights for Power and Protection status.  

 Dual Fusing: Equipped with \bm{2 \times 30\text{A}} fuses for system security.
