ZEUS HIGH PERFORMANCE AMPLIFIERS
The Zeus ZXi Series products have been designed to a very high level of performance, with features unavailable in
any other product. All of the amplifiers have variable crossovers built in, with added touches such as subsonic
filter, bass equalization and a remote Level control module(some models) that allows subwoofer Level control from
the drivers seat.
To ensure years of listening pleasure, all amplifiers have a built in diagnostic mode that will detect shorted speaker
leads, low impedance, dangerous high temperatures, DC shorts and will shut down the amp to prevent serious
damage.

GENERAL INSTALLATION PROCEDURE
1
System Design
Installation
The success of any car stereo system relies on several factors, such as the system design, execution of the installation, and system setup. Please
remember that any system is only as good as its weakest link.
Please remember that higher power systems are not necessarily useful purely for high sound pressure levels, but also to establish a headroom capability, to
reproduce musical peaks cleanly without distortion. Lower power amplifiers will clip earlier than their more powerful cousins, and cause loudspeaker failure when
overdriven, due to the harmonics generated by a clipped signal, thus overheating voice coils.
Amplifiers should be mounted with the fins running horizontally for best convection cooling, to minimize overheating. Purchase the best quality RCAcables you can
afford, for reliability and less engine noise interference in the audio system.
General:
Run the wiring so that RCAcables are at least 18“ away from power and speaker cables. Keep RCAcables away from electrical devices in the vehicle that can cause
electrical noise, such as electric fuel pumps, emission control modules and other on-board electronic modules.
Power and ground connections(see the features matrix on page 7 for proper gauge cables per amplifier):
Use a sufficient gauge power cable and ground cable using the chart below as reference to what size wire you require. Zeus series amplifiers require at least 4 gauge
power wire. In a multi amplifier system, add the total value of the manufacture recommended fusing to get your total system amperage. Some applications may
require multiple runs of power wire to meet the system requirements. In multi amplifier systems it is advisable to mount a large enough fuse right at the battery, and
run one or multiple +12 volt power cables to a fused distribution block near the amplifiers. It is then a simple matter to connect the +12 volt terminal of each amplifier
to the distribution block. During this process, please ensure that the main power fuse is removed to avoid shorting the electrical system. The main fuse must be within
12” of the vehicles battery.
Ground each amplifier with as short a ground lead as possible directly to the vehicle chassis using at least 4 gauge wire or equivalent to the size of the amplifiers’
power wire. Use a ground distribution block, if you wish, but it is extremely important to keep the main ground lead from this distribution block to the chassis as short
as possible , not more than 12“. The ground connection integrity to the chassis is very important, and the best way to achieve a good, solid electrical and mechanical
contact is to use a large round crimp lug, crimped and soldered to the ground cable. The next step is to scrape the paint off the vehicle chassis , slightly larger than
the ground lug, at the connection point. Drill a clearance hole in the chassis, the same size as the lug hole, and use a bolt, spring washer and nut to securely fasten
the ground lug. Use petroleum jelly to coat the bolt/lug connection, to prevent oxidization with time.
TIP: Use the same approach when installing head units, equalizers or any audio equipment for that matter - run short individual grounds from each piece directly to
the vehicle chassis, to minimize ground loops and system noise.All power, ground and speaker connections should be crimped and soldered for reliability. Make sure
that none of the cable insulation can chafe against exposed metal in the vehicle, causing short circuits to the chassis.
Safe connection sequence:
After all cables are run, connect speaker wires to the speakers and amplifiers, then run and plug in RCAcables. Next, connect all power, ground, and remote turn on
leads. Now connect all +12 volt cables to the amplifier/s and distribution blocks and fuse holders. Finally, connect the main +12 volt cable to the battery, with the main
fuse removed, and we are almost ready to power up the system.
Power up the system:
The following procedure may seem like overkill, but there is nothing more frustrating when turning on a system for the first time, and it does not work properly
immediately.
First, make sure the head unit is off, and turn all level controls to minimum (counterclockwise), including the head unit volume control. Set all equalizers to 0 dB (no
boost), and all crossover frequency controls at approximate frequencies, as recommended by the loudspeaker manufacturer. Set all input selector and crossover
switches as required for the application. Remove all amplifier fuses, and insert the main fuse at the battery. If the fuse does not blow, you can insert the fuse in one of
the amplifiers, and we are ready to turn on the system. Turn the head unit on, insert a CD, or select a radio station, and increase the head unit volume control. If the
system sounds fine, turn off the head unit, and install fuses in the remaining amplifiers, one by one, till the complete system is powered up and functioning properly.
It is highly recommended that the amplifier be mounted to a board of MDF or other solid
structure using the 4 mounting screws provided. Avoid mounting the
amplifier to metal as this can introduce noise and other unwanted issues. When mounting
the amplifier, ensure that it is mounted HORIZONTALLY, as shown in the diagram above, for
optimal heat dissipation. Mounting amplifiers to speaker enclosures is not recommended as
this can cause damage to the amplifier components. When choosing a location for
mounting the amplifier, ensure that you check for clearance from wires, gas tank, electrical
devices and brake lines etc.
NOTE: This Matrix is a general rule
of thumb. Please refer to the
manufacturers specific
requirements. ZXi specifications

The ZXi60.4+1K has three sets of inputs:
Line inputs on RCAjacks for channel pairs 1&2, 3&4, and MONO channel 5. These inputs can be used in
various combinations, to suit the application, depending on the settings of the INPUT MODE switch, and
the X-OVER switches for channels 1&2, and channels 3&4, respectively.
INPUT MODE slide switch:
- In the CH2 position,ALL five amplifier inputs are selected from the CH1/CH2 RCAjacks. Channel 5
receives a mono mixed signal.
- In the 4CH position, channel pair 1&2 receive input signal from RCAjacks CH1 and CH2, and channel
pair 3&4 receive input signal from RCAjacks CH3 and CH4. Amono mixed signal from these four RCA
jacks are also fed to channel 5.
- When 5CH DISCRETE is selected, each channel receives an input signal from its respective input RCA
jack. Channel 5 has two jacks on its LINE INPUT, which are summed together.
CH1/2 X-OVER slide switch:
- HI: Selects the HIGH PASS filter, variable from 10Hz to 15KHz.
- FULL: Sets this pair to full range operation.

CH 5:
- The channel 5 functions were chosen to be very specific to mono bass operation, and not switchable:
- The LOW PASS filter has a variable range from 30 Hz to 150 Hz.
- The BASS EQ gives a bass boost, 0 to +10 dB, at 45 Hz.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE
Channel 5 on the ZXi60.4+1K
General:
At this point you are ready to get more specific on the settings for your amplifier.
Bass EQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-10dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to
your subwoofers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a
low volume or a low recording quality as this can result in high distortion and possibly clipping.
Low Pass:
The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. The 12 o’clock position is a great starting point. EXAMPLE: If you
adjust the Low Pass to 80Hz, the amplifier will not play frequencies above 80Hz but will play frequencies from 80Hz to the chosen Subsonic frequency.
Level Control Setup:
Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the
head unit volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input
sensitivities properly to the head unit output signal level.
It is important to match the amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual.
If the Radio/CD output sensitivity is 2 volts, then adjust the amplifier LEVEL input to 2 volts.
If you are not sure what the Radio output sensitivity is, follow these general guide lines:
Turn the level control up slowly, till you hear distortion, then back off a few degrees on the control. If at any point your amplifier goes into protection, you will need to turn the Level to the
left a bit and then try again. If you reach a point where the output does not increase, stop turning the Level control to the right as the amplifier/subwoofer combo has reached its maxx
output in this application.
Sit back and enjoy the music!

General:
At this point you are ready to get more specific on the settings for your amplifier.
High Pass:
-When in Hi Pass operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this
point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the High Pass to 100Hz, the amplifier will not play frequencies below 100Hz but will play frequencies from
100Hz to the highest frequency the amplifier is capable of reproducing.
-When in Low Pass/Bandpass operation, this setting acts as a low frequency cut off for your system reproduction aka Subsonic Filter. The point that you set it at cuts off any frequencies
from reproduction beyond this point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the High Pass to 60Hz, the amplifier will not play frequencies below 60Hz
but will play frequencies from 60Hz to the chosen Low Pass frequency.
-When in Flat/Full operation, the Low Pass crossover is bypassed.
Bass EQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-10dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to
your speakers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a low
volume or a low recording quality as this can result in high distortion and possibly clipping.
Low Pass:
The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. Turning the potentiometer all the way to the right is a great
starting point. EXAMPLE: If you adjust the Low Pass to 120Hz, the amplifier will not play frequencies above 120Hz but will play frequencies from 120Hz to the chosen Hi Pass or
Subsonic frequency.
-When in Hi Pass operation, this setting is bypassed.
Level Control Setup:
Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the
head unit volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input
sensitivities properly to the head unit output signal level.
It is important to match the amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual.
If the Radio/CD output sensitivity is 2 volts, then adjust the amplifier LEVEL input to 2 volts.
If you are not sure what the Radio output sensitivity is, follow these general guide lines:

output in this application.
