Allows you to fine tune the level matching between your source and the power amplifier 04 WORLD RECORD BREAKING TECHNOLOGY MOUNTING LOCATION Before you start the installation it will be necessary to find a mounting location for the amplifier Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation Two popular mounting locations are in the trunk or under the seat Select the location in which you wish to mount the amplifier Use caution when mounting amplifier there are many wires gas lines vacuum lines brake lines as well as a gas tank in the automobile Make sure you know where they are when mounting the amplifier to avoid puncturing lines shorting wires or drilling holes in the gas tank Once you are ready use a pencil to mark the mounting holes in the bottom panel After you have marked the locations of the holes move amplifier out of the way and drill small starter holes to make the tapping screws easier to install Use provided screws to tighten down the amplifie on ee EN EPEE 4 05 www dbdrive net POWER CONNECTIONS Fuses Speaker RADIO S REMOTE TURN ON OUTPUT IN LINE POWER FUSE MOUNTED WITHIN 12 FROM BATTERY RECOMMENDED NOT PROVIDED IMPORTANT
5. Before making any connections disconnect the car s battery until the installation is completed to avoid possible damage to the electrical system Connect The Amplifier To The Car s Battery At times the amplifier will need to draw large levels of current that cannot be provided by any circuit in the car s fuse box We recommend using a 4 to 8 gauge power wire for your connections depending on the amplifier and length of the wire Strip one end of the wire and prepare for connection Loosen the terminal on the amplifier marked 12Volt and insert wire and then securely tighten Use caution to make sure no stray wire stands come in contact with surrounding terminals causing short circuits Run the wire directly to the positive terminal of the car s battery Make sure to use an in line fuse within 12 of the car s battery to protect the electrical system and amplifier against short circuits and or power surges Connect The Ground Terminal Of The Amplifier To The Car s Chassis For the ground connection use a 4 to 8 gauge wire black to connect to the terminal marked Ground and then connect it to the car s chassis Try to keep the length of the cable as short as possible preferably less than 6 Also make sure that the point on the car where the connection is to be made is free of paint and dirt Connect The Remote Terminal Of The Amplifier To A Switchable 12v Source This connection allows the amplifier to be turned on and off w
