AudioControl ACM-4.300 Four Channel Micro Amplifier
The AudioControl ACM-4.300 is a compact, powerful four-channel amplifier to enhance your car audio system. It delivers 50 watts RMS per channel at 4 ohms and 75 watts RMS per channel at 2, ensuring high-quality sound reproduction. Its small footprint allows for versatile installation in various vehicle types.
High-Power Output in a Compact Design
Despite its micro size, the ACM-4.300 delivers substantial power to drive your car speakers effectively. It ensures precise and dynamic audio performance with 50 watts RMS per channel at 4 ohms and 75 watts RMS per channel at 2 ohms. The amplifier can also be bridged to provide 150-watt RMS at 4 ohms, offering flexibility for different system configurations.
Advanced Integration Features
The ACM-4.300 has a preamp and speaker-level inputs, facilitating seamless integration with factory and aftermarket audio systems. Its GTO™ (Great Turn On) Signal Sense feature allows the amplifier to power on automatically when it detects an incoming audio signal, simplifying the user experience. Additionally, the built-in Linkwitz-Riley crossover provides selectable high-pass filtering at 80 Hz or 120 Hz or can be bypassed, enabling precise control over the audio output.
Durable Construction and User-Friendly Design
The ACM-4.300 is constructed with high-quality materials and is built to withstand the rigors of automotive environments. Its reversible cover plate offers flexible mounting options for a clean and discreet installation. The amplifier's compact dimensions (9.4 inches wide, 3.0 inches deep, and 1.75 inches high) and lightweight (2.2 lbs) make it suitable for installations where space is limited.

| General Specifications | |
Frequency Response Frequency Response in a car amplifier refers to the range of audio frequencies it can amplify, typically measured in Hz. For example, a response of 20Hz to 20kHz indicates the amp can handle deep bass to high treble, covering the full audible spectrum.
|
|
S/N Ratio S/N Ratio (Signal-to-Noise Ratio): A measure of an amplifier's ability to amplify audio signals relative to background noise. A higher S/N ratio indicates clearer sound, as more of the output is dedicated to the signal rather than noise.
|
|
THD+N @ Rated Power THD+N (Total Harmonic Distortion plus Noise): A measurement of the total distortion and noise introduced by an amplifier. Lower values indicate cleaner audio reproduction, as less distortion and noise affect the output signal.
|
|
Input Voltage Range Input Voltage Range: The range of voltage levels an amplifier can accept from the audio source. It determines compatibility with various head units or signal processors, ensuring optimal signal strength without distortion or clipping.
|
|
Crossover Slope Crossover Slope: The rate at which frequencies are attenuated beyond the crossover point, measured in dB per octave. Steeper slopes (e.g., 24 dB/octave) provide more precise separation between frequency ranges, improving sound clarity.
|
|
Sub Sonic Filter Subsonic Filter: A filter that blocks extremely low frequencies below a set threshold, protecting subwoofers from distortion or damage caused by inaudible, power-draining bass signals.
|
|
Variable Subsonic Freq Variable Subsonic Frequency: A feature that allows adjustment of the subsonic filter's cutoff point, enabling fine-tuning to block unwanted low frequencies and optimize subwoofer performance based on system setup.
|
|
Fuse Rating Fuse Rating: The maximum current an amplifier can handle before its fuse blows, protecting the unit from damage. It indicates the amp’s power capacity and helps ensure safe operation within the electrical system.
