Connecting Inputs
inch of wire. Twist the ends to secure
loose strands.
LOW-LEVEL INPUTS
You can connect your auto sound system’s
low-level line out jacks to the amplifier’s
LOW
INPUT
jacks.
If your auto sound system does not have
low-level line out jacks, see “High-Level
(Speaker Wire) Inputs” to connect your am-
plifier.
Note: For the best results, use shielded au-
dio cables (not supplied) available at your lo-
cal RadioShack store.
1. Temporarily place the amplifier as close
as possible to the selected mounting
location.
2. Connect one end of a shielded audio
cable to the auto sound system’s left line
out jack.
3. Connect the other end of the cable to
the amplifier’s
LOW INPUT LEFT
jack.
4. Repeat Steps 2 and 3 to connect the
auto sound system’s right line out jack to
the amplifier’s
LOW INPUT RIGHT
jack.
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 two speaker
outputs, see “Two Speaker Outputs” on
Page 9 to connect your system’s speaker
outputs to the amplifier using either a floating
or common ground connection.
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 amplifier using either only the
rear speakers or two amplifiers to connect
both the front and rear speakers.
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 harness and the sup-
plied twist-on terminal connectors to make
the appropriate connections.
