PH2000W/ 1D
12 13
Variable 10dB boost at 40Hz.
Perfect tool for high SPL scores.
Full time low-pass variable filter
12dB/Oct slope, range from 50
to 300Hz
Through output feeds other
amplifiers in the audio system.
NOT EFFECTED BY THE LOW-
PASS FILTER.
The gain knob is not a volume control.
It is designed to match the input level
of the amp to the output level of the
source unit. Over driving -clipping- the
input stage of the amp will cause
damage to the amplifier (Please refer
to table for settings).
Before you install the amp, take note of the following:
#1. You have to confirm that your power supply can
deliver spontaneous power to the amplifier when
needed to propel the load.
#2. Bullet-proof ground: the ground cable must be 4-
gauge minimum, it should be very short, and well
grounded to the chassis.
Three 25A Fuses
* Test the alternator output. Factory alternators will produce 60-80 amperes at best. Wear and
heat will reduce the output by 40%.
* Alternator ground (-) must be reinforced, use 4-gauge cable instead of the factory 8-gauge.
* Alternator positive (+) to battery (+) must be reinforced. Use 4-gauge cables.
* Check your battery condition. Batteries degrade after a while.
* Battery (+) to amplifier (+) must be a 4-gauge cable.
* Ground amplifier to chassis using 4-gauge cable, keep the cable short (Maximum 2-feet).
* Use 1 farad capacitor to compensate for surges in demand.
* We recommend the use of one (1) auxiliary battery.
