Two heavy fork crimp terminals to connect + and to amplifer but you do only need them if you use heavy cable or to make the installation look nicer. Four to eight fork crimp terminals to connect the speaker cables but you do only need them if you use heavy cables or want the installation to look nicer. One fork crimp terminal to connect the remote wire to the amplifier, but you need it only to make it look nicer. Four to eight splicers to connect speaker cables to high level input cable, if high level input is used. Wire ties Insulating grommet or insulating tube

High current draw
The CA12 is a mono amplifier with high power output. The current draw is also high so you must make sure that your vehicles power system (battery and alternator) can provide all the power you need. 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.

Wiring
Power and Outputs
Power terminal ( +12V)
Connect the fuse holder as close to the vehicle battery + as possible, using AWG5 = 16 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 AGU fuses +12V REM GND like the DLS FH1B. Fuse value 60 A if you use a AWG5 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 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. [. . . ] 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. Disconnect signal cables from amplifier to see if noise disappears. [. . . ]
