Wiring Instructions; Ground Connection - Pyle Power Sports PLUTV49BTR User Manual

PRECAUTIONS
• This unit is designed for negative ground 12-14.50 Volts (DC) operation only.
• Use speakers with an impedance of 4 Ohms
• Avoid installing the unit where:
• It would be subject to high temperatures, such as from direct sunlight or hot air
from the heater.
• It would be exposed to rain or moisture.
• It would be subject to dust or dirt.
• If your vehicle or boat is parked in direct sunlight and there is a considerable rise
in temperature inside the car, allow the unit to cool off before operation.
• When installing the unit horizontally, be sure not to cover the heatsink fins with
the floor carpet.
• If this unit is placed too close to the resources radio, an interference may occur.
In this case, separate the amplifier from the car radio.
• This power amplifier employs a protection circuit to protect the transistors and
speakers if the amplifier malfunctions. Do not attempt to test the protection
circuits by covering the heatsink or connecting improper loads.
• Do not use the unit with a weak auto battery as its optimum performance depends
on a normal battery supply voltage.
• For safety reasons, keep the volume of your audio system moderate so that you
can still hear normal traffic sounds in a reasonable distance.

WIRING INSTRUCTIONS

POWER CONNECTION
The battery terminal (BATT ) must be connected directly to the positive terminal
of the vehicle battery to provide an adequate voltage source and minimize noise.
Connecting the battery terminal lead to any other point (such as the fuse block)
will reduce the power output and may cause noise and distortion. Use only #12
gauge or thicker (smaller gauge #) wire for this lead and connect it to the terminal
of the battery after all other wiring is completed.

GROUND CONNECTION

The ground terminal (GND) connection is also critical to the correct operation of
the amplifier. Use a wire of the same gauge as the power connection (#8 or thicker)
and connect it between the ground terminal (GND) of the amplifier and a metal
part of the vehicle close to the mounting location. This wire should be as short as
possible and any paint or rust at the grounding point should be scraped away to
provide a clean metal surface to which the end of the ground wire can be screwed
or bolted.
