Features & specs

The CO-35.4 offers RCA and AUX-Inputs, which are connected through cinch cables with the preamplifier-outputs of the head unit (head unit, MP3-Player, iPhone, iPad). If the head unit (OEM-RADIO) has no RCA-Output, than it is possible to connect the speaker output to direct RCA-Input and switch has to be turned to "HI". If signal is presented at RCA, AUX or High Input, the amplifier automatically turns on and the power LED lights. With the aid of the gain-controller and variable crossover you are able to adjust the amplifier on to your prefered taste of hearing, the circumstances of the vehicle and to the speakers.

Power Connection

 

11416_1.jpg

  1. Battery Disconnection

    First disconnect the power supply of the vehicle. This works out the best 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 sice 6 - 10). Make sure, that the connection with the vehicle chassis is free of paint, dirt and dust.

     

  3. +12 V Power Connection

    Connect the +12 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 a maximum of 30 cm. Requirement for a perfect function of the amplifier is a qualitative high end fuse holder as well as a suitable cable cross section (AWG sice 6 - 10). This fuse protects the amplifier and the vehicle against the possibility of a short circuit in the power cable.

     

  4. Remote Connection (Optional)

    You can optional connect the REM-terminal of the amplifier to the remote-output (automatic 12 V antenna-output) of the head unit. Therefore use a 0,5 - 1,5 mm power cable.

     

  5. High Level Input

    If the radio (normally original radio) has no RCA output and remote output (automatic 12 V antenna output) it is possible to connect the speaker output from headunit direct in "High Level Input". If the amplifier get a signal from head unit output, the amplifier will turn on.

Caution

  • Take extra care when making the connections. Make sure that no electrical cable, gas tank, hydraulic brakes or other components get damaged.
  • Allow enough cooling and air circulation and avoid installing the unit in small closed boxes or close to parts that heat up easily.
  • Keep the amplifier away from liquid, moisture, heat and foreign materials.
  • This amplifier can only be used in vehicles with 12V DC power supply.
  • Never install the power supply cable with other original vehicle wires (gas cables), fan motors, control modules etc.
  • Install the signal cable (cinch cable) as well as speaker cable far away from the power cables to avoid interference with music signals.
  • To avoid dangers of cables binding, squeezing or breaking, use the cables supplied with your amplifier.
