M70.4 Mini Power Automotive Woofer Amplifier — Class D 4-Channel Stereo (Bridgeable 2Ch), 12V

Compact M70.4 car amplifier built to drive woofers and full-range speakers with efficient, high-output performance. MOSFET power supply: uses metal-oxide semiconductor FETs that rapidly switch between full conduction and cutoff to deliver high-efficiency power. Class D design: advanced Class‑D topology with dedicated linear circuitry improves power delivery and sound clarity while cutting distortion and boosting efficiency. Bridgeable: channels can be bridged on a 2- or 4-channel setup to provide a significant increase in available output. 2-Ohm stable: reliably supports 2‑ohm speaker or subwoofer loads for greater power and louder playback. Variable low-pass filter: adjustable low-pass crossover lets you control which low frequencies are sent to the subwoofer.
