[. . . ] If you have a bad battery or alternator in can result in a poor sound or even worse, a broken battery or alternator. Professional Tip: If amplifier installation kits are available with different size of power cable, chose the most heavy power cable to improve sound quality and to allow more amplifiers to be installed now or later. If possible buy AWG 4 = PL 21 mm2 (or heavier) cable for best performance. 3 CAD11 Remote terminal ( REM ) Wiring Power and Outputs Power terminal ( +12V) Connect the fuse holder as close to the vehicle battery + as possible, using AWG4 = 21 mm2 or heavier cable. Use ring crimp terminal cable to connect to battery +. Apply silicon grease to the fuse to prevent corrosion. Use a fuse holder for ANL fuses +12V REM GND +12V REM GND like the DLS FH2B. Fuse value 100 A if you use a AWG4 cable. For RCA cable signal input: Connect the radio power antenna lead = remote turn on/off from the car stereo to the amplifier remote connection. This turns on the amplifier whenever the car stereo is turned on. 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. For High Level input: We recommend you to connect the remote wire as described above. The amplifier will produce soft on / soft off operation this way. You must set the Hi level/Low level switch to Low level position in this case. In the case that there is no remote voltage available from the car stereo or you want to simplify the installation, the amplifier can be turned on/ turned off by the high level input voltage. This is done when the Hi level/Low level switch is set to Hi level position. There is a small disadvantage that this function gives soft turn off operation but some plop sound when switching off. +12V REM GND +12V REM GND DLS DLS FH 2B fuse holder Connect the battery cable to the +12 Volt on the amplifier. If you want to improve the power capacity you can add a Power capacitor of 1 Farad in parallel with the DC input. 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. [. . . ] Check quality of system ground connection. This can be helpful against most noise problems. Ensure that all equipment has a common ground point. Check quality of earth strap connection from battery negative terminal to chassis. [. . . ]
