Power Acoustik EG4‑1000: Edge Series 4-Channel 1000W Class A/B Amplifier with Auto Signal Sensing and Bridging Support
The Power Acoustik EG4‑1000 belongs to the Edge Series—a lineup built for reliable, full-range power delivery in daily-driven and enthusiast-grade systems. With Class A/B topology, bridging capabilities, and a high-gloss, satin silver chassis, this 4-channel, 1000-watt amplifier seamlessly blends performance with refined visual detail.
Consistent Output with Flexible Configuration
This full-range amplifier produces up to 1000 watts of peak power and offers multiple RMS output configurations:
- 65W x 4 @ 4Ω
- 125W x 4 @ 2Ω
- 250W x 2 @ 4Ω bridged
The EG4‑1000 is built to drive front and rear components, or a subwoofer when bridged, making it ideal for multi-speaker setups or entry-level bass expansion.
Auto-Sensing High-Level Input for Factory Radios
Many modern vehicles rely on OEM head units without RCA outputs. The EG4‑1000 features automatic high-level signal sensing, eliminating the need for a remote wire. Once the signal is detected from speaker-level inputs, the amp powers on automatically—ideal for factory integrations where traditional wiring is not practical.
Tuning Tools for Custom Sound
Equipped with a full suite of audio shaping features:
- Variable high-pass and low-pass crossovers (50–400Hz)
- 12dB/octave slope for sharper filtering
- Selectable 12dB bass boost for added low-frequency impact
- Preamp RCA outputs to easily chain additional amplifiers
These tools help fine-tune your system for clarity, separation, and tonal control across speaker types and listening environments.
Reliable Construction, Safe Operation
Built on a military-grade printed circuit board with a PWM MOSFET power supply, the EG4-1000 ensures clean and efficient power delivery. Additional protections include:
- Thermal shut-off
- Short circuit protection
- Overload safeguards
Terminals support 4-gauge power cable input and 8-gauge speaker wire, ensuring adequate current delivery and speaker load handling.
