Installation
Installation Notes
The amplifier is generally mounted in the rear trunk area but can be
mounted in any convenient area such as beneath a seat. Please be sure to
locate this unit where you have reasonable air circulation and protection from
moisture. When considering the mounting location you should minimize the
length of the power and speaker leads. Minimizing both leads will yield a more
reliable installation. It is also important to ensure that the heat sink fins
are not against a panel or a surface, preventing air circulation. Do not
install the amplifier on a subwoofer box or on vibrating parts of the vehicle,
since the vibrations can cause damage to the amplifiers electrical components.
Installation of the amplifier
Before starting with the installation, mount the provided mounting brackets
on the amplifier. Mark the location for the mounting screw holes by using the
amplifier as a template. Drill holes at the marked locations as and firmly
fasten the amplifier in place with the mounting screws supplied in the
accessory kit. Before drilling or cutting any holes, investigate the layout of
your automobile thoroughly: Take care when working near the gas lines or
hydraulic lines and electrical wiring.
Electrical Connection
Ground (GND)
This wire is the electrical ground and must be fastened securely to the
vehicle chassis. The best method is to use a threading sheet metal screw since
the threads cut into bare metal. Ensure that all paint or other insulationis
removed from around the hole area, and using self tapping screw, securely
affix the bare wire ends to the vehicle chassis. Use as short a piece of cable
as possible – use the same gauge as was used for the +12V cable. Make sure
that the connection is safe and stable.
Remote (REM)
Connect the remote wire of your headunit with the remote turn-on of the
power amplifier.
Battery Connection (+12V Power)
This wire is usually connected directly to the positive battery terminal.
Ensure that the + power supply wire is fused via an in-line fuse near by the
battery. Please use a sufficient gauge (min 16 mm) with spade lug with
insulating sleeve.
Fuses
The integrated amplifier fuses protect the units from short circuit and
overload. The fuse rating is for 4 Ohm loads (impedance) of the speakers, for
2/1 Ohm loads the fuses may have to get increased by up to 50%/100% in case of
higher power consumption.

Troubleshoating
System does not turn on
- Check all fuses.
- Check all connections.
- Measure the +12 volt and remote turn on voltages at the amplifier terminals. If these are non existent or low, take voltage measurements at fuse holders, distribution blocks, the head unit’s +12 voit and remote leads to localize the problem.
Noise problems
- Check the speaker wiring
- Speakers are damaged
No Signal at all Channels
- Set Balance and Fader from head unit on Zero-Position
- Check wiring (Amplifier, Speakers)
- Speakers are damaged
- Subsonic Filter is adjusted too high or Lowpass Filter is adjusted too low
Hiss or white noise
- Speakers are overload
- High levels of white noise usually occurs when amplifier level controls are turned up too high – readjust according to the procedures in section “Setting up systems after installation for best performance”
- Another problem that can cause excessive hiss, is a noisy head unit – unplug the amplifier input RCA cables, and if the hiss level reduces, the source unit is at fault.
No Stereo-Sound or Low Output
- Check speaker wiring (- and +)
Amplifier Protection-Mode (red LED is illuminated)
- Speaker cabels are shorted
- Inadequate cooling – relocate or remount to provide better natural airflow over the fins. Driving high power levels into low impedances – back off on the volume control, and/or make sure you are not loading the amplifier with less than the recommended loudspeaker impedance.
- Make sure that the battery voltage, as measured at the amplifier’s +12 volt and ground terminals, is 11 volts or more.
Electrical Interference
The inside of an automobile is a very hostile electrical environment. The
multitude of electrical systems, such as the ignition system, alternator, fuel
pumps, air conditioners to mention just a few, create radiated electrical
fields, as well as noise on the +12 volt supply and ground. Rememaber to
isolate the problem – first unplug amplifier input RCAcables, if the noise is
still present, check the speaker leads, if not, plug the RCA’s back, and
investigate the source driving the amplifier, one component at a time.
A ticking or whine that changes with engine RPM:
- This problem could be caused by radiation pickup of RCA cables too near to a fuel pump or a distributor, for instance, – relocate cables.
- Check that the head unit ground is connected straight to the vehicle chassis, and does not use factory wiring for ground.
- Try to supply the head unit with a clean + 12 volt supply directly from the battery +, instead of using a supply from the in dash wiring/fusebox.
This type of noise can be more difiult to pinpoint, but is usually caused by some kind of instability, causing oscillations in the system.
Aconstant whine:
- Check all connections, especially for good grounds.
- Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis.
- RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections.
Caution!
In this amplifier are integrated protection circuits. Short Circuit Protection
engaged: The ampifier will turn off and try to come back on immediately. The
amplifier will cycle like this indefinitely, with “blips” of sound each time.
If this is the case, check your speakers and wiring for low impedance and
short circuits. Thermal Protection engaged: The amplifier will turn off and
several minutes later will come back on. In this case, ensure that there is
nothing blocking the normal convective airflow of the amplifier. No
obstruction should be within 2° of the amplifier on all sides.
NOTE: Low battery voltage will cause the ampifer to run warmer and
possibly damage the amplifier. If the red LED still lighting up after all re-
checking, the amplfier is damaged. Please send then a detailled malfunction
description and a copy of the invoice of purchase together with the device to
you car audio retailer.
