HIGH-LEVEL (SPEAKER WIRE) INPUTS

using either a floating or common ground connection.

If your auto sound system does not have low-level line out jacks but has only speaker outputs, connect your auto sound system’s speaker outputs to the amplifier’s HIGH IN- PUT jacks.

•If your auto sound system has four speaker outputs, see “Four Speaker Outputs” on Page 10 to connect your system’s speaker outputs to the ampli- fier using either a floating or common ground connection.

•If your auto sound system has two speaker outputs, see “Two Speaker Out- puts” on Page 11 to connect your sys- tem’s speaker outputs to the amplifier

Note: A floating ground connection lets the amplifier provide more power to each speak- er, but requires that you connect a separate wire to each speaker terminal. A common ground connection lets you use fewer wires to connect the speakers to the amplifier, but reduces the amount of power supplied to the speakers from the amplifier.

Use the supplied wire harnesses and the supplied twist-on terminal connectors to make the appropriate connections.
