STACT™(ST
abilized Apex Current Topology) Reduces power supply stress by 50%. In The STACT design,
inversion is done at the power amplifier drive stage. Since the fully symmetrical power amplifier
produces no evenharmonic distortion itself and all preamplifier circuitry is run completely inphase,no
even harmonic distortion phase reversal occurs and power is better distributed throughout the amplifier.
Advanced Trident™ Protection Topology Protects against potentially harmtul dmage in the following
situations:
1. Output Protection against short circuits or improper loads.
2. Voltage Inconsistencies protects against ground fault (speaker shorts to vehicle chassis) and an
under/over
voltage condition on the battery input.
3. Thermal Protection puts the amplifier into thermal rollback or shuts the amplifier down in extreme
thermal
conditions.
Hawkins Bass Control-Fully adjustable subwoofer equalization ciruit providing frequency and
bootst(“Q”)subwoofer for optimum subwoofer perfomance. Afrequency tracking subwoofer filter
protects subwoofer from potentially harmful low frequency information and maximizes output i a usable
range.
Tone Sweep Calibration Routine Automatically configures and optimizes the power supply to the
connected speaker load.
Continuously Variable Crossover Network 12 dB/octave low pass cross-overs variable from 50 Hz to 5k Hz
with a range selection switch
RCA Line Output Provides a full range signal output to drive other amplifiers.
Wire Connections Power and ground connections accept I\0 gauge cable, while the speaker
connections utilize dual 8 gauge connections.
ATT switch ‘ON’ for high voltage input(4V~12V) capability. This swich ‘ON’ must be used for peaker level
input on common ground head-units or for high voltage line drivers.

Maximum Fuse Rating
You will need to install an in-line fuse or circuit breaker in the power wire within 18" of the battery. This fuse
or circuit breaker is to protect your vehicle from fire in case the power wire shorts to the vehicle body.
If you are only using one amplifier, use the fuse rating indicated in this chart. If you are using more than
one amplifier, add up the fuse ratings for all the amplifiers. This sum is the rating for your fuse or circuit
breaker. You may also want to add a power distribution block near your amplifiers to distribute large
gauge power cable to multiple amplifiers.

WIRING
The following is a basic formula to be used as a guide to determine current draw. A 50% amplifier
efficiency rating is used as an average. Your new VGA amplifier is more efficient than most other amplifiers.
This formula is to be used as a guideline. Using wire of a larger gauge can only improve the current transfer
of your system. Do not use smaller gauge wire.
Total Amplifier RMS output x 2 = Total Input Wattage from car
Total Input Wattage
= Current Draw (in Amps)
Supply Voltage
Example: A VGA amplifier has two channels at 175w per channel RMS rating into 4 Ohms (175 x 2 = 350).
You would use the formula in the following way:
350W x 2 = 700W
700W
= 58.3 Amps Total current draw.
12V
If the same amplifier is driven into a 2 Ohm stereo or 4 Ohm mono load, double it's 4 Ohm RMS rating. All
VGA amplifiers will effectively double their power at this load.
(160W x 2) x 2 = 640W
640W
= 116.7 Amps Total current draw.
12V
If you are using more than one amplifier, add up the total current draw for all of them and choose the
appropriate gauge based on the grand total.
POWER WIRE CALCULATOR
NOTE: The ground wire must be the same gauge or larger as the power wire.
