This owners manual is written in easy english and uses a lot of drawings to simply the installation and use of the above amplifiers. [. . . ] Check all locations and placements carefully before making any cuts, drilling any holes or making any connections. Disconnect Battery Before starting the installation, always disconnect the negative terminal of the battery. 2 CA10 Tools and material needed Tools: Flat and Phillips screwdrivers Wire cutter Wire stripper Electric drill with drills Crimping tool Digital multimeter or test lamp Wire brush, scraper or a piece of an abrasive sheet to remove paint for a good ground connection Grease to protect the ground connection from corrosion Material: Speaker wire: minimum 12 AWG = 4 mm2 for subwoofers Sheet metal screws for mounting the amplifier to the amplifier board and the amplifier board to the car + some extra for fuse holder, amplifier ground etc. Electrical insulation tape ½ inch thick plywood or particle board for the amplifier to be mounted upon. Amplifier installation kit: If available, buy an amplifier installation kit. This is what you have to buy if you buy the items separately 20- 25 feet = 6- 7. 5 meter power cable, preferably AWG 4 = 21 mm2 or heavier 1 pc of fuseholder to install close to the car battery + fuse 150 Ampere. 20 feet of AWG 15 = 1, 5 mm2 wire for remote turn on / off cable from radio. - 20 feet or 5 meter for trunk installations -12 feet or 2 ­ 3 meter for under seat installations Two min. 8 gauge ring crimp terminals ­one for connection to the battery plus and one for the amplifier ground connection. 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. Two to four 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 only to make it look nicer. Wire ties Insulating grommet or insulating tube Routing wires Stereo head unit 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 CA10 Remote terminal ( REM ) Wiring Power and Outputs Power terminal ( +12V) Connect the fuse holder as close to the vehicle battery + as possible, using AWG 4 = 21 mm2 or heavier cable. Use ring crimp terminal cable to connect to battery +. 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. 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. +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. [. . . ] The phase shift in passive crossovers sometimes makes it necessary to change polarity. + Battery 1, 5 Volt + - - Professional Tip: Installing in trunk When installing the amplifier in the trunk, run the power wires along the same path as the other vehicle wiring. Many cars have insulated channels for wiring. you will have to remove the door sill trim and the carpet. Professional Tip: Securing wires Use wire ties to bundle together when possible. (But never bundle speaker wires or signal cables together with power wires. Professional Tip: Crimp connections Purchase crimp connectors and crimping tool. [. . . ]
