CONTROL FUNCTIONS

1. SPEAKERS

Connect speakers/subwoofers to these terminals. Be sure to check wire for proper

polarity. Never connect the speaker cables to chassis ground.

2. +12 Volt Power

Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of

the vehicle battery or the positive terminal of an isolated audio system battery.
Warning: Always protect this power cable by installing a fuse or circuit breaker of the

appropriate size within 18 inches (45cm) of the battery terminal connection.

3.Remote Turn On

This terminal turns on the amplifier when (+)12 volt is applied to it . Connect it to the

remote turn on lead of the head unit or signal source.

4.GND

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 amplifier power cable or larger. CAUTION: Do not connect this terminal directly
to the vehicle battery ground terminal or any other factory ground points.

5. RCA input jacks

These RCA input jacks are for use with source units that have RCA outputs. A source
unit with a minimum level of 200mV is required for proper operation. The use of high
quality twisted pair cables is recommended to decrease the possibility of radiated noise
entering the system.

6. High level inputs

The high level inputs are for use with speaker level wiring. Some source units do not
have RCA outputs, so use this terminal for speaker level signal input. CAUTION: Never use
high level input when RCA inputs available.

CONTROL FUNCTIONS

7. REMOTE

Connect the remote controller to control the subwoofer amplifier volume from the

driver seat location, for ease of adjustment during playing.

8. LEVEL Control

The level control will match the amplifiers sensitivity to the source units signal
voltage. The Operating range is 200mV minimum to 5V maximum. This is NOT a volume
control!

9. Low Pass Filter Control

This control is used to select the desired low pass x-over frequency. The frequency
can be adjusted from 40Hz to 220Hz for all bass mono models.

10. Subsonic Filter Control

This control can filter out unwanted low frequency from 10Hz (OFF) to 50Hz. This
function will increase the power handling of your woofers.

11. Bass Boost Frequency and Level Control

By adjusting these two knobs, you can boost a wanted frequency to a wanted level.
The center boost frequency is adjustable from 30Hz to 90Hz, the boost level is adjustable
from 0dB to 12dB.

12. Phase Control

This control can adjust speaker output phase from 0 to 180 degrees infinitely to
match your system phase characteristics.

13. X-over mode and frequency Control (Full range)

These controls allow control over the frequencies played for the front channels.
There is an option for Low Pass, Full Range or High Pass. In LP or HP mode the frequency
range is from 50Hz to 4kHz.
