1. Power Connections for input power, chassis ground, and remote turn-on, use a
minimum of 18 gauge copper wire for power and ground connections; power wire
should be fused with 1 Amp fuse
2: RCA Front & Rear Outputs RCA output jacks provide a fadeable-full range signal to
your front and rear amplifiers
3. RCA Inputs allow for a normal stereo signal input from various sources
4. RCA Sub Output provides a low pass signal to your bass amplifier
5. AUX Input Gain Adjustment is used to match the input level with the output level of
the source unit connected to the AUX input. When properly adjusted both sources
(AUX and Main) should play at the same volume level. The adjustments are individual
with one for the left and one for the right channel
6. Low Pass Frequency (LPF) Adjustment controls the cutoff frequency of the LPF on
the “Sub Out” channels, the crossover filter is switchable from 45Hz to 60Hz.
7. Subwoofer Level Adjustment raises and lowers the level of just the “Sub Out”
channels to fine tune level based on musical content
8. Volume Control raises and lowers the volume on all of the outputs simultaneously
9. Fader Adjustment allows you to adjust the level between the Front and Rear
channels
10. Input Selector Switch selects the Main/Aux
11. Equalizer Level Adjustment 9 individual controls at set at fixed frequencies of
50Hz, 125Hz, 250Hz, 500Hz, 1KHz, 2KHz, 4KHz, 8KHz and 16KHz with ±10dB of
adjustment one each

Installation Guidelines
- Always mount the EQ9.0 where it can be easily reached to make
adjustments
- Avoid mounting EQ9.0 to a sub enclosure or any other high vibration
areas
- Do not cover EQ9.0 with carpet or any other material
- Do not mount EQ9.0 in the engine compartment or anywhere that will
subject it to high temperatures (i.e. direct sunlight, or heater), moisture,
dust or dirt
- Use rubber or plastic grommets to protect wires when routing them
through metal
- Always keep signal wires away from high current power wires
- The ground connection should always be the first connection made
Wiring Instructions
Ground Connection (GND) The main ground connection should be made
between the GND terminal on the unit and a metal part of the vehicle
close to the mounting location. This wire needs to be as short as possible to
minimize the possibility of induced noise. You should use 18ga or larger
copper wire for the ground connection. The metal point on the vehicle
where the ground connection is made needs to have all paint removed
and be scuffed down to the bare metal. The ground wire should have a
ring terminal soldered to it and be bolted directly to the vehicle with the
use of a star washer. Do not ground the unit near existing (factory) ground
points. These areas generally have multiple devices grounded to them
and can cause induced noise.
Power Connection (+12V)
The main power connection should be made at the battery. This will
ensure that EQ9.0 receives the best possible connection to minimize noise.
There must be an inline fuse (1 amp) placed in series with the unit. The fuse
should be within 18” of the battery. You should us 18ga or larger copper
wire for the power connection. The power wire should have a ring terminal
soldered to it and be bolted to the vehicle’s battery. Do not install the fuse
in the holder until all the system’s connections have been made.
Remote In (REM)
The remote in terminal should be connected to the remote lead from the
car stereo. This remote lead from the source unit will trigger a +12V output
only when the car stereo is turned on. If the source unit does not provide a
remote turn-on you can use the accessory terminal in the car’s fuse block.
This will however turn the unit on and off with the key, regardless of
whether the source unit is on or off.
