POWER/GROUND/REMOTE
D5 amplifiers need proper power and ground connections to deliver maximum
performance and efficiency. This is typically the least understood part of the
installation process. Voltage drops due to poor quality connections and/or
poor grounding practices will rob your audio system of power that could be
used for listening to music. These voltage drops will create increased current
draw and will make it easier for noise to enter your system.
Your new amplifier has a fully regulated power supply. It is designed to make
full power even if the voltage changes. It will draw more current at lower
voltages to make that power. Try to ground your system to a single point in
the vehicle.
The gauge of the power and ground cables must be capable of handling the
current needed by the entire system. Power and ground cables must be of the
same gauge. If the alternator is not capable of supplying enough power for
both the vehicle AND the audio system, a high output alternator should be
installed for best performance.
A Word About Batteries
and High Output Alternators...
The battery in your car is a chemical storage device for electrical energy
generated by the alternator. It is capable of briefly supplying high currents for
cold starting the vehicle as well as powering other important electrical loads
either partially or entirely for a limited period when the engine is off.
In order to supply the power required for ignition, lighting, large audio
systems etc. a car needs its own efficient, reliable, and constantly available
source of energy. When the engine is stopped, the battery is the vehicle's
energy source. When the engine is running, the alternator is the on-board
"electricity generating plant." It is the job of the alternator to supply power
to all current-consuming loads (including the audio system).
Alternator output, battery capacity, and power demand of all electrical loads
and systems must be matched as ideally as possible so the entire system is
reliable and trouble-free in operation.
