SoundQubed F4-1600 Four-Channel Full-Bridge Amplifier

The SoundQubed F4-1600 puts substantial four-channel power into a compact chassis for car-audio builds where speaker output and installation space both matter. Its listed output reaches 400 watts RMS per channel at 2 ohms, with a 10× crossover frequency multiplier for added crossover-setting flexibility.

RMS Power by Configuration

• 4 ohms stereo: 250 watts × 4 channels RMS
• 2 ohms stereo: 400 watts × 4 channels RMS, 1,600 watts total
• 4 ohms bridged: 800 watts × 2 channels RMS

The 1,600-watt figure is combined output, not power per channel. Match speaker power handling and final impedance to the intended configuration. Use the specified 4-ohm bridged rating when planning a bridged installation; do not assume 2-ohm bridged operation.

Build Around Your Speakers

Use the four-channel configuration for a compatible multichannel speaker setup, or plan around the listed two-channel bridged output when the speakers and wiring suit that configuration. Set crossover points and gain for the connected speakers rather than treating the amplifier's full frequency capability as a suitable operating range for every driver.

Installation Planning

Have power wiring, grounding, circuit protection, and the vehicle's charging capacity evaluated for the intended system. Allow ventilation around the heat sink and confirm mounting clearance before installation. Additional wiring, integration equipment, and electrical upgrades may be required depending on the vehicle and existing equipment.
