Synergy WFO 8.4D 4-Channel Amplifier 250X4 / 0GA Inputs

The Synergy Audio WFO 8.4D is a Korea-built 4-channel amplifier delivering solid headroom for both daily drivers and serious SPL builds, with 250W x 4 at 4 ohms and 330W x 4 at 2 ohms for dynamic musical transients.

• Power @ 4 Ohm: 250W x 4 @ 14.4V — provides ample clean volume for four speaker channels in a typical front/rear setup, with headroom for musical transients without clipping.
• Power @ 2 Ohm: 330W x 4 @ 14.4V — higher current capability lets you push low-impedance loads for crisper, louder performance when your speakers demand more power.
• Power @ 4 Ohm Bridged: 630W x 2 @ 14.4V — two bridged outputs allow pairing channels for a dedicated sub or high-current mono bass channel with strong excursion control.
• Frequency Response: 10Hz – 35kHz — extended range ensures bass fundamentals and high-end detail stay within reach of the amp’s output, aiding transparent sound across the spectrum.
• Signal-to-Noise Ratio: >100dB — low noise floor helps maintain clarity and reduces hiss in quiet passages and during high-volume playback.
• Dimensions: 300mm L x 239mm W x 69mm H — compact footprint relative to power, important for fitment in trunk, under-seat, or custom enclosures.
• Subsonic Filter: Channels 1/2 10Hz–500Hz; Channels 3/4 10Hz–500Hz — protects woofers from ultralow bass that can cause overexcursion and inefficiency.
• Low Pass Filter: Channels 1/2 50Hz–800Hz x10; Channels 3/4 50Hz–800Hz x10 — precise bass limiting to keep low frequencies resonant without encroaching on midrange clarity.
• High Pass Filter: Channels 1/2 20(200k)Hz–800(8k)Hz x10; Channels 3/4 20(200k)Hz–800(8k)Hz x10 — prevent bass from muddling midrange drivers, enabling cleaner vocal and instrument reproduction.
• Bandpass Capable: Yes — offers flexible crossover configurations for targeted frequency ranges and driver combinations.
• Operating Voltage: DC 8V–16V — compatible with typical automotive electrical systems, allowing reliable operation across a range of vehicle power conditions.
• Input Sensitivity: 8V – 200mV — accommodates a wide variety of head-unit outputs and preamp levels for clean, distortion-free input signals.
• 0GA Inputs: 0 GA wiring compatibility — supports heavy-gauge power/ground wiring for robust, low-impedance installations.

In a real car build, the WFO 8.4D suits a four-channel front stage with optional sub amplification via bridging, delivering clean highs and controlled bass with flexible crossover options. Its Korean-design heritage and component quality target consistent, high-performance sound in daily driving and competition-grade setups alike.
