User manual DLS CA10ENG

[. . . ] Signal lead plugs and cables. Installation Before you begin installation Before you begin you need to read the manual, to have some tools, cables and other material available. There is one such list of material on the following page. Amplifier location Important Allow air circulation around the amplifier. The DLS Classic series of amplifiers have a compact design that allows great flexibility in mounting. When you select a location, do remember that the amplifier generates a lot of heat. Choose a location where air can circulate freely around the amplifier. [. . . ] Apply silicon grease to the fuse to prevent corrosion +12V REM GND For RCA cable signal input: Connect the radio power antenna lead = remote turn on/off from the car stereo to the amplifier remote connection. You can either use the built in remote cable in the RCA cable itself or use a separate cable. Sometimes a small disturbance may enter the amplifier coming from the remote voltage , through the built in remote wire and into the RCA cable. Thus we recommend to use a separate remote wire and run the RCA lead separate from remote wire, power cables and speaker cables. You can either use a crimp fork terminal or insert the cable directly into the amplifier terminal. If there is no remote voltage available from the stereo, you must connect to the ignition key through the radio or any accessories fuse. +12V REM GND DLS DLS FH 2B fuse holder Connect the battery cable by a crimp fork terminal ( spade ) to the +12 Volt on the amplifier. Be sure to use a rubber grommet or a plastic insulating tube where the cable passes the firewall or other places when it can easily be jammed. Use ty-wraps to secure to existing cables in the engine compartment. Ground Terminal ( GND ) Connect to a good chasis ground. The ground connection should be clean, unpainted metal to provide a good electrical connection. Use a wire brush, a scraper or a piece of an abrasive sheet to clean the metal. Protect with silicon grease or by paint applied afterwards. +12V REM GND Fuses Use only 30 ampere ATC blade type fuses. CA 10 uses five 30 ampere fuses. 30A 4 CA10 Input and controls Input Wiring Inputs may be low level from the RCA output of the car stereo. If your head unit has a separate RCA sub output we recommend that you to use it for connection with the CA10 Low level input Use a pair of shielded stereo audio cables with RCA type jack. Most trunk-mount amplifiers need a 20 feet RCA cable ( appr 5 ­ 6 meters). Most under the seat installations require 12 feet ( 2 ­ 3 meters) RCA cables. Avoid placing the RCA cable close to speaker cables, power cables and remote control cable. Connect to input socket A & B. Bass Boost on CA10 Bass Boost is used to Bass Boost increase the bass 6dB 12dB volume. You can select the amplification 0dB 18dB between 0 dB ( no amplification ) and 18 dB ( full amplification ). This function is used to compensate for the bass box function and to adjust for your own taste of bass. The Bass Boost level can also be adjusted from the front seat by using the remote level control box. Connect the cable coming with the amplifier between the control box and Bass Boost connector on the amplifier. Input Level control The input level control, 5V ­ 0, 25 V, Level matches the output of your radio to the input of the amplifier. [. . . ] Four 4 ohm subwoofers 1 ohm load Speaker Reconnect Battery When wiring is complete, reconnect the battery negative terminal. + + - - Test power wiring 1. The cone should move outwards when the wire touches the battery, and inwards when the battery is removed. If it is the other way around, the speaker has been connected backwards and it must be removed and connected correctly. If your system also has a subwoofer connected through a passive 6 or 12 dB crossover, try to connect this with various polarity and judge what sounds best. [. . . ]
