Tools Needed for Typical Installation (not supplied)
•
Phillips screwdriver (#2 or medium sized)
•
Wire cutters
•
Wire strippers
•
Mounting / Ground connection screws
•
Ring connectors (Large enough to accommodate your
method of grounding and power connection)
•
Speaker wire – 16 gauge or larger
•
Connector crimper tool
•
Grommets (sized to work with the power wore you plan to
use in your installation
•
Tube of silicon Sealant
Current Supply
The information below is a basic formula you can use to
determine approximate maximum current draw. A 50%
amplifier efficiency rating is used as an average. This formula
is only a guideline. Using wire of a larger gauge improves the
current transfer of your system, so if in doubt, always use
larger cables. Do NOT use smaller gauge wire.
Total 4-Ohm rated RMS output x 2 = Total Input Wattage
Total Input Wattage/Supply Voltage = Current Draw (in
Amps)
Example:
Your TD BLUE has 2 channels at 75 watts per
channel RMS into 4-Ohms (75 x 2 = 150W). You would use
the formula below:
150W x 2 = 300W/12.5V = 24 Amps Total Current Draw
The chart on the next page w ill help you to determine the
gauge of power / ground cables necessary for proper
operation of your Tube Driver.
