Why Choose This Product?
The A2000.1D combines multiple bass-tuning controls with a wired remote, so you can make adjustments at the amplifier or from the cabin. Its MOSFET circuitry, pulse-width-modulated power supply, and aluminum alloy heatsink are part of its design for mobile audio use.
Nickel-plated audio and power terminals provide corrosion-resistant connections. The amplifier also uses Surface Mount Technology and angled terminals for a streamlined installation.
Installation & Compatibility Notes
This amplifier is specified for 12V mobile vehicle audio systems and subwoofer loads of 1, 2, or 4 Ohms. Confirm your subwoofer’s impedance and the corresponding power rating before connecting it.
The power and ground terminals accommodate 4 AWG wire, and the speaker terminals accept 14 AWG wire. The amplifier uses an external fuse; the supplied specifications do not state a fuse rating. Check the installation requirements for your system before wiring.
Frequently Asked Questions
How much power does the Hifonics A2000.1D provide at each impedance?
Its listed output is 1 x 2000 watts at 1 Ohm, 1 x 1000 watts at 2 Ohms, and 1 x 500 watts at 4 Ohms. Maximum power is listed as 2000 watts.
Does the amplifier include a bass remote?
Yes. The package includes an HFR-31 wired bass remote control for adjusting bass levels from the vehicle cabin. The supplied product details describe its control as illuminated.
What wire gauges do the terminals accept?
The power and ground terminals accommodate 4 AWG wire. The speaker terminals accept 14 AWG wire.
How does high-level auto turn-on work?
The amplifier detects a 6V DC offset voltage rise over the high-level speaker inputs when the source unit powers on, allowing it to turn on without a separate remote wire.
What should I check before pairing it with a subwoofer?
Confirm that the subwoofer configuration matches a 1, 2, or 4 Ohm load, then use the corresponding power rating when planning your system.
What comes in the package?
The listed included items are the Hifonics A2000.1D ALPHA amplifier and HFR-31 wired bass remote control.
