CONNECT THIS CABLE DIRECTLY TO THE FRAME OF THE VEHICLE. MAKE SURE THE METAL FRAME HAS BEEN
STRIPPED OF ALL PAINT DOWN TO THE BARE METAL. USE THE SHORTEST DISTANCE POSSIBLE. IT IS ALWAYS A GOOD
IDEA TO REPLACE THE FACTORY GROUND AT THIS TIME WITH A LARGER CABLE EQUAL TO THE NEW DIRECTLY TO THE
VEHICLE BATTERY GROUND TERMINAL OR ANY OTHER FACTORY GROUND POINTS.
5.RCA INPUT/AUTO HI-LOW LINE CONVERTOR
THESE RCA INPUT JACKS CONNECT WITH YOUR SOURCE UNITRCA LOW L EVEL OUTPUTS OR VIA OPTIONAL
ADAPTER WITH YOUR SOURCE UNIT SPEAKER HIGH LEVEL OUTPUTS. THE USE OF HIGH QUALITY TWISTED PAIR
CAR AUDIO CABLES IS RECOMMENDED TO MIND POSSIBILITY OF DISTURBANCE THE AUDIO SIGNAL.
6. REMOTE(MONO BLOCKS)
CONNECT THE REMOTE CONTROLLER TO CONTROL THE SUBWOOFER AMPLIFIER VOLUME FROM THE DRIVER
SEAT LOCATION, FOR EASE OF ADJUSTMENT DURING PLAYING.
7. GAIN CONTROLLER
GAIN CONTROL WILL MATCH THE AMPLIFIERS SENSITIVITY TO THE SOURCE UNITS SIGNAL VOLTAGE. THE
OPERATING RANGE IS 10V TO 200MV. THIS IS NOT A VOLUME CONTROL!
8.LOW PASS FILTER CONTROL (MONO BLOCK)
THIS CONTROL IS USED TO SELECT THE DESIRED LOW PASS X-OVER FREQUENCY. THE FREQUENCY CAN BE
ADJUSTED FROM 60HZ TO 220HZ FOR ALL BASS MONO MODELS.
9. SUBSONIC FILTER CONTROL (MONO BLOCK)
THIS CONTROL CAN FILTER OUT UNWANTED LOW FREQUENCY FROM 0HZ (OFF) TO 60HZ. THIS FUNCTION WILL
INCREASE THE POWER HANDLING OF YOUR WOOFERS.
10.BASS BOOST LEVEL KNOB (MONO BLOCK)
THIS CONTROL ADJUSTS THE BOOST LEVEL OF THE BASS BOOST CENTER FREQUENCY. IT CAN BE ADJUSTED
FROM 0 TO 12DB. COMBINING WITH BASS BOOST FREQUENCY, YOU CAN ACCURATELY MATCH THE AMPLIFIER
PERFORMANCE TO WOOFER RESPONSE.
11.BASS BOOST FREQ KNOB (MONO BLOCK)
THIS CONTROLS THE BOOSTED CENTER FREQUENCY. THE FREQUENCY CAN BE ADJUSTED FROM 30HZ TO 120HZ
ACCORDING TO YOUR CAR AUDIO SYSTEM PERFORMANCE. (I.E. WHEN YOU ADJUST THIS KNOB TO 50HZ, THE
AMPLIFIER WILL BOOST THE FREQUENCY AROUND 50HZ.) THIS FUNCTION SHOULD BE ADJUSTED COMBINING WITH
BASS BOOST LEVEL TUNING.
12. X-OVER MODE (FULL RANGE)
TO ADJUST THE OPERATING FREQUENCY RANGE OF THE AMP. WHEN SWITCHED TO LPF OR HPF, THE
CORRESPONDING FILTER CAN ADJUST THE OPERATING FREQUENCY RANGE. WHEN PUSHING THE SUBWOOFER,
SWITCH TO LPF MODE. WHEN PUSHING SMALL CALIBER FULL FREQUENCY SPEAKERS OR MIDDLE AND HIGH
FREQUENCY LOUDSPEAKERS, SWITCH TO HPF MODE. WHEN PUSHING LARGE CALIBER FULL FREQUENCY SPEAKERS,
SWITCH TO FULL MODE. WHEN SWITCHED TO FULL MODE THE FILTERS WILL NOT FUNCTION.

15. CLIP
LED INDICATOR IS TO SHOW SIGNAL CLIPPING, IF THE INPUT SIGNAL WAVE IS BEYOND THE RANGE.
BY LOWERING THE GAIN, THE CLIPPED PORTION WILL GO BACK WITHIN THE INPUT RANGE AND THE LED
INDICATOR WILL TURN OFF.
OCCASIONAL LED "ON" ( OCCASIONAL FLICKERING) OF LED WOULD BE PERMISSIBLE IN SOME INSTALLS, BASED
ON PERSONAL PREFERENCE.
16.CROSSOVER
THIS CROSSOVER SWITCH SELECTS (LPF) LOW PASS FREQUENCIES. THE OFF POSITION IS FOR FULL RANGE.
THE CROSSOVER FREQUENCY RANGE TO SELECT THE LOW PASS FREQUENCY (LPF) IS BASED ON YOUR SPEAKERS
