Precision Power DCX 500.1 Stereo Amplifier User Manual


 
Note: The power connector is inserted into the amplifier with
the wire clamping screws in the up position as shown below.
The two negative outputs are common to each other as the two
positive outputs. A speaker may be connected to either
terminal.
GROUND WIRING
Locate an area near the amplifier(s) that is metal and clean an area
about the size of a quarter down to bare metal. Inspect the area
around and underneath to be sure you will not drill into wires, brake
or fuel lines, etc. Drill a pilot hole in the middle of this area.Terminate
the ground wire with a ring connector and attach it to the bare metal
using a #8 sheet metal screw and washer or preferable, a bolt, nut
and a star washer. (not supplied). We suggest crimping and
soldering this connection. After the
connection is complete, coat the area
(on both sides) with silicone or some
similar material to prevent rust from
developing on the bare metal. If your total current draw is over 80
amps (
or total power is over 500 watts
). Keep the ground and power
wires as close together as possible, and use the same gauge wire
for both.This will ensure that you have a good ground path, and may
eliminate such potential problems as engine noise and overheated
amplifiers.
