Connections
-
Disconnect battery
First disconnect the power supply of the vehicle. Best way is to remove ground connection of the battery. -
Ground connection
Connect the GND (ground) connection of the amplifier with the car chassis. Keep this wire as short as possible (not longer than 100cm) and use a suitable cabel cross section (AWG 13 – AWG 9). Please make sure that the connection point to chassis is clean, no paint on (sand if necessary) and dust free. -
+12 V power supply
Connect the +12 V contact of the amplifier with a power cable via a fuse to battery directly.
Attention: The cable length between car battery and fuse holder must not exceed 30cm! Please also use a suitable cable cross section and fuse -
Remote connection : If using the Low-Level (RCA) inputs of the amplifer you have to also connect the remote input to the amplifier turn on output or electrical antenna output of your headunit. Details can be found in your headunit‘s manual.
-
Signal input : You can use speaker outputs of headunit or RCA low-level outputs of headunit for this amplifier. Please note not to connect both inputs at the same time.
-
AUX-inputs: The amplifier has 2 different AUX inputs. AUX 1 use 3.5mm jack to connect to external sources. This input has an integrated signal detection to turn on amplifer.
The AUX 2 input uses a 6 pin connection for specialized Audio System accessories. Please contact your local dealer for more details.
Caution
Please take the following precautions when installing your amplifier:- a) Take extra care when making the connections. Make sure that no electrical cable, gas tank, hydraulic brakes or other components get damaged.
- b) Allow enough cooling and air circulation and avoid installing the unit in small closed boxes or close to parts that heat up easily.
- c) Keep the amplifier away from liquid, moisture, heat and foreign materials.
- d) This amplifier can only be used in vehicles with 12V DC power supply.
- e) Never install the power supply cable with other original vehicle wires (gas cables), fan motors, control modules etc.
- f) Install the signal cable (cinch cable) as well as speaker cable far away from the power cables to avoid interference with music signals.
- g) To avoid dangers of cables binding, squeezing or breaking, use the cables supplied with your amplifier.
-
Pre-Out: The amplifier has a 2-channel pre-out to connect further amplifiers.
-
Speaker outputs: The CO-40.5 DSP-BT has 5 amplified speaker outputs. The speaker impedance of each speaker must not fall below 2 Ohm.
DSP CONTROL APP
All settings of the amplifier can be accessed by the Audio System DSP Control app. This software is under ongoing development and can be found at www .audio-system.de/dsp/
Troubleshooting
This power amplifier is featured with an efficient protection system to prevent
any damages like overheating, overvoltage, short circuit and DC offset on
speaker output.
In order to check any problem, first turn down all volume levels of the head
unit, afterwards turn the headunit off.
Some errors can be checked in DSP Control App. These are errors where amplifier
still turns on (blue LED on).
-
Amplifier doesn‘t turn on, LED is not lightening
ground connection properly connected?
+12 V properly connected?
remote wire properly connected?
fuse(s) inserted and OK?
voltage at amplifier OK? (multimeter) -
Amplifier without output, LED is turned on
High-Level or Low-Level input properly connected?
over- our undervoltage? (multimeter)
output short circuited? (DSP Control App)
proper source selected? (DSP Control App)
source routing ok? (DSP Control App) -
Amplifier gets quieter
adequate airflow to the amplifier?
impedance alright? (multimeter)
Attention
The amplifier slowly levels down the output power when getting too hot until temperature is cold enough again! -
Amplifier fuse burned
proper ground connection?
proper speaker impedance?
Attention
When exchanging the fuse alsways use same fuse ratings original! -
Sound distorted
input gain matched? (DSP Control)
output gain set to loud? (DSP Control)
speaker connectors alright?
crossover frequencies matching speakers? -

Attention
Please contact your specialized dealer if the amplifier is still not
working after checking the troubleshooting guide!
For warranty adjustments / repairs always attach the original invoice!
Opening the amplifier will void warranty!
