M70.4 Mini Power Automotive Woofer Amp — 4-Channel Class D Car Amplifier 12V (Bridgeable to 2Ch), 2Ω Stable

Compact M70.4 mini power amplifier built for car audio and woofer applications, delivering efficient, high-quality output in a small 12V package. MOSFET Power Supply: Metal Oxide Semiconductor Field-Effect Transistors switch rapidly between conduction states to produce a highly efficient power source. Class D: This Class-D amplifier employs targeted linear-style circuitry to boost power and audio clarity while cutting distortion and improving overall efficiency. Bridgeable: Channels on this unit can be combined (for either 2- or 4-channel configurations) to achieve a substantial jump in power output. 2-Ohm Stable: Designed to run comfortably at 2-Ohms, allowing speakers or subwoofers to receive more power and greater volume. Variable Low-Pass Filter: An adjustable low-pass filter puts you in control of which frequencies are sent to the subwoofer for tighter, cleaner bass response.
