Usina Spark Smart 160A Dual-Voltage Car Audio Power Supply

Adjustable DC power for a compatible car audio setup

The Usina Spark Smart 160A is an automotive power supply with automatic dual-voltage AC input and adjustable 12.5–14.4V DC output. Its listed 160A output is specified at 12.5V under a resistive load, making the operating conditions an important part of planning your installation.

When preparing your next listening session, use the integrated voltmeter to monitor output voltage while your installer matches the supply to the system's electrical requirements. This unit supplies electrical power; it does not amplify an audio signal.

Current and power ratings are carried over from the existing specifications and were measured with a resistive load. Output may vary with mains voltage and conditions of use. The input bands are separate operating ranges, not a continuous 100–250V range. Do not assume 160A output is available at every output voltage.

Installation and Battery Compatibility

Professional installation is recommended. The existing specifications reference 35mm² output cable, a 3 × 2.5mm² grounded input cable and a 32A input circuit breaker. A qualified installer must verify these against the manufacturer's manual, local electrical requirements, cable routing and the actual installation.

Confirm battery chemistry, capacity and supported charging profile before connecting a battery. Float mode does not establish compatibility with every battery type. Verify output polarity, grounding, mains capacity and ventilation before operation.

Do not assume the supply will maintain battery charge indefinitely while the sound system is running. Connected demand and available output determine the electrical balance.

Included Item and Warranty

The existing listing specifies one Usina Spark 160A dual-voltage automotive power supply and a 12-month warranty. Check the supplied warranty terms for coverage and conditions.

Choose the Smart 160A dual-voltage version for a carefully matched car audio setup requiring adjustable DC power.
