Alpha 1K Class D Mono Amplifier

The Alpha 1K is a Class D monoblock car amplifier rated at 1000 W maximum power and 500 W RMS. It delivers 350 W at 4 ohms, 500 W at 2 ohms and 1000 W at 1 ohm in a compact chassis measuring 7.28 x 2.30 x 5.71 inches.

For Bass Systems Needing High Power at Low Impedance

This amplifier suits installations that run a single subwoofer at 1 or 2 ohms and want 500 to 1000 W RMS from a small footprint. Buyers who need stereo output, multi-channel surround or full-range component amplification should look at a different topology.

Straightforward Install With Built-In Protection

The mono design means only one speaker channel and one set of RCA inputs to connect, while nickel-plated terminal blocks accept power and ground cables cleanly. A remote bass knob is included for level control. The 4-way protection circuit guards against thermal, short-circuit, overload and DC-offset faults, reducing the risk of damage from wiring mistakes.

Questions about this item

What impedance subwoofer do I need so the amp can deliver its 500 W RMS rating?

Wire a single 2-ohm subwoofer to the mono output; the specs list 500 W x 1 @ 2 ohms as the RMS figure.

If I keep my factory head unit, will the 200 mV – 6 V input sensitivity range accept its speaker-level outputs?

Yes, the variable input sensitivity adjusts from 200 mV up to 6 V, covering typical factory speaker-level signals without a line-output converter.

After installation, how can I verify the protection circuitry is active and the amp is not in fault mode?

Power the system and confirm the amp stays on without shutting down; the 4-way protection (thermal, short-circuit, overload, DC offset) engages automatically if a fault occurs.
