One power amplifier. A suitable power supply and speakers are needed to complete your setup.

Before use

Use a compatible 12V DC supply and confirm the current requirement on the unit: the supplier’s home-use note says 2A, which conflicts with its detailed specification of more than 3A. Do not connect directly to a 24V supply; a suitable step-down device is required. The supplier recommends a cigarette-lighter supply for 12V vehicle use and warns that a direct battery connection may introduce noise. Have vehicle wiring checked by a competent installer. Maximum advertised wattage is not a guaranteed continuous output rating; actual output depends on the complete setup.
