IMPORTANT: Before installation your power amplifier, we recommend to read the owner´s manual carefully
and to follow the instructions regarding connection and fitting exactly.
IMPORTANT: Your proof of purchase is evidence of warranty claim for repair or replacement. Keep your proof
of purchase, manual and original packaging.
ATTENTION: Pay attention to advices and instructions of the car manufacturer.
Audio SystemGermany accepts no liability for hearing loss, bodily injury or property
damage as a result of use or misuse of our products. We recommend installing the equipment by an
authorized service center or dealer. A professional fitting and connection is the requirement for further
warranty and perfect sound.
ATTENTION: Use of sound components can impair your ability to hear necessary traffic sounds and may
constitute a hazard while driving your automobile.
Congratulation on your purchase of your new h + c-Series amplifier.

1. Battery disconnection:
First, disconnect the power supply of the
vehicle by removing the ground cable of
the battery.
2. Ground connection:
Connect the GND (ground) connection
of the amplifier with the car chassis.
Keep this cable as short as possible (not
longer than 50 cm) and use a suitable
cross section (AWG size 7-5).
Make sure, that the connection with the
vehicle chassis is free of paint, dirt and
dust.
3. +12 V Power connection (+24 V in co- 700.1 d 24 V):
Connect the +12 V (+24 V in co- 700.1 d 24 V) contact of the amplifier with the supply cable via a fuse
directly to the vehicle battery. Keep in mind, that the length of the cable from fuseholder to vehicle battery has to be
maximum 30cm. For the amplifier to function at its best, use a high quality fuse holder and suitable cable preferably
AWG 7-5 cable. This fuse protects the amplifier and the vehicle against the possibility of a short circuit in the power
cable.
4. Remote connection:
Connect the REM-terminal of the amplifier to the remote-output (automatic 12 V
(+24 V in co- 700.1 d 24 V) antenna-output) of the head unit. Use a 0,5 - 1,5 mm power cable.
The H-340.1 D + co-200.1 have a remote out (RO) for additional amplifier.

a) Take care of a professional attachement. Pay attention, that no electrical cable, gas tank, hydraulic
breakes or other components get damaged.
b) There has to be enough cooling and air circulation. Avoid the installation in small closed boxes or close to
heatening parts.
c) Protect the amplifier from fluids, wetness, heat and foreign material as well as from other influences.
d) The amplifier is only to be built into vehicles with a 12 V DC power supply
(+24 V in co- 700.1 d 24 V).
e) Never install the power supply cable with other original wires of the vehicle (gas cables), fan motors,
brand control moduls etc.
f) Install the signal cable (cinch cable) as well as the speaker cable far away of the power cables to avoid
troubles with the music signal.
g) The cables of your amplifier have to be installed, so that there is no danger of binding, squeezing or
breaking.
Please follow the instructions during the installation of your amplifier:

Optional a wire remote controller RTC can be installed to adjust the output level.
In this regard, AUDIO SYSTEM germany recommends to adjust your amplifier through a specialized
service center, dealer or a specialist.
The h/c Series amplifier offers RCA-Inputs, which are connected through cinch cables with the preamplifier-
outputs of the head unit. If the head unit (OEM-RADIO) has no RCA-Output, than it is possible to connect the speaker
output direct to RCA/Cinch-Input of the amplifier.
The Input Mode has to be switched on “HI“. Important: the Gain-Controller has to be adjusted to minimum, then
carfully turn up the volume. If signal is presented, the amplifier automatically turns on. Adaptercable HLAC und
z-pro rca hi can be purchased at your specialized dealer.
With the aid of the variable subsonicfilter, lowpassfilter, phase shift-controller, bass boost
(only CO-650.1 and co- 700.1 d 24 V) and the gain-controller you are able to adjust the amplifier on
to your prefered taste of hearing, the circumstances of the vehicle and to the speakers.

Please note that this units are mono block units and have only one channel. Connecting to either the positive or
negative of either of the two connections will end in the same result as both positive connections (or both negative
connections) are tied together inside the unit. For example, if you connect two 4 ohm subwoofers, the amp will
parallel the connections for a 2 ohm load.

trouble shooting
Occuring an error the protection-LED will light in red. In order to check the problem, first turn down all levels of
the head unit, afterwards turn it off.
This power amplifier is featured with an efficient protection system to prevent any damages like over-heating,
overvoltage, short-circuit and DC at the loudspeaker output.
