5. d to allow adjustment to properly match the output of the radio This is one of the most misunderstood adjustments By rotating the control in the clockwise direction the amplifier s input will become more sensitive and the music will play louder This is not a volume control and you will not get more power out of the amplifier in the maximum position It may seem to deliver more output but actually the system is only playing louder faster as you turn the volume control on the radio Ideally to properly level match the system the goal is to achieve maximum output from the amplifier without distortion at about 3 4 of the volume control To determine if the amplifier s gain is set properly turn the system on and slowly increase the volume control You should be able to use about 3 4 volume before the system gets loud but not distorting It is very important when making these adjustments that you do not over drive the speakers at point of distortion this will cause permanent damage to the speakers If you are unable to achieve 3 4 volume before distortion you will need to adjust gain control in this case you would reduce the gain The gain controls should be adjusted very slowly It may help to have another person to assist you by adjusting the gain controls while you listen for distortion FINE TUNE THE SYSTEM 13 Select the crossover type on the amplifiers side panel Low pass is selected in this example for subwoofers You can add up to
6. e provided by any circuit in the car s fuse box We recommended using an 10 to 12 gauge power wire for your connections depending on the amplifier and length of the wire Strip one end of the wire to connect to the terminal on the amplifier marked 12V Loosen screw terminal and connect bare wire and 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 an 10 12 gauge wire black to connect to the terminal marked GND 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 with the power control of the radio If the radio has a Remote output wire connect it to the amplifier s terminal marked REM using a 16 gauge wire or heavier Now when the radio is turned on the amplifier will automatically turn on This connection can also be made to the radio s Power Antenna
7. hear traffic sounds and emergency vehicles Use common sense when listening to your system IMPORTANT Before making any connections disconnect the car s battery until the installation is completed to avoid possible damage to the electrical system Serial Model 1 SAFETY PRECAUTIONS Fuse amplifier s power wire at the battery Be sure to fuse the power wire within 12 of the car s battery This will protect the car s battery in case of a short circuit between the power amplifier and battery THIS IS A MUST the amplifier s built in fuse will only protect the power amplifier not the car s battery Use high grade wire connectors To ensure maximum power transfer and secure safe connections it is recommended to use high grade barrier spades for connection at amplifier and terminal rings for connection at battery Do not run any wires underneath vehicle Exposed wires have a chance of being cut or damaged It is best to run all wires through the vehicle under the carpet and or side panels This lends to a cleaner installation and less risk of damage Use caution when mounting amplifier Remember there are many electrical 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 Run signal wires away from electrical wires To avoid possibility of induced noi
