Connecting Inputs
If your auto sound system has two line out jacks (left and right), connect the auto sound system
to the amplifier.
Note: For the best results, use shielded audio Y-adapters (not supplied) available at your local
RadioShack store.
HIGH-LEVEL (SPEAKER
WIRE) INPUTS
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
using either a floating or common
ground connection.
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.
