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 grand 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.
CHARGING SYSTEM
If your total current draw is over 100 amps (
or total output power is
over 600 watts
), you are probably exceeding the capability of your
charging system. Dimming lights and fluctuating voltage are solid
indicators that you need to upgrade your alternator, battery, or both.
You should also check the condition and current capacity of the
stock battery negative cable and connections, and replace or
upgrade as necessary. Keep in mind that your amplifiers simply
convert electrical energy to acoustical energy, and any electrical
deficiency will compromise the performance of your sound system.
