The Synergy Audio WFO 5.1D is a Korean-built high-output monoblock amplifier designed for serious subwoofer systems in daily drivers, demo builds, and SPL competition vehicles. Rated at 7,200 watts RMS at 1 ohm on 14.4V, it delivers the current capability and controlled bass output needed for demanding multi-subwoofer setups.
Built around a dual MOSFET PWM power supply, four high-current transformers, a heavy-duty double-sided 2 oz. copper PCB, and a high-mass aluminum heat sink, the WFO 5.1D is engineered to perform under sustained electrical and thermal load. Its 16V-capable design delivers up to 7,600 watts RMS at 1 ohm when used with a properly upgraded high-voltage electrical system.
The WFO 5.1D also features adjustable subsonic and low-pass filters, remote gain control, and digital linkable/strappable capability for compatible high-output amplifier configurations.
