POWER CONNECTION MONO CHANNEL AMPLIFIER - APPLICATIONS PLA3100D/PLA4600D INTERCONNECTION EXAMPLE 1 Subwoofar wi th a Oual-Voicecoil @ MA STER J I' "d IMPORTANT ! Before making any connections, disconnect the car' s battery until the installation is completed to avoid possible damage to the electrical system * The + 12V DC power cable should be heavy gauge stranded copper cable with heavy insulation , since it draws power directly from the positive battery terminal. Select the cable gauge al least 10mm 2• And the ground cable gauge should be the same as the +12V DC. * Connect the +12V Power terminal to the battery ( + ) position terminal. An in- line fuse must be installed in the + 12V power cable near the battery less than 50mm . Wit hout one , an accidental short circuit could pose a fire hazard and damage your amplifier. Connect the fuse holder to battery, however, do not install fuse at this time . * Connect the GROUN D Power terminal direclly to the battery ( - ) position terminal or the car chassis. Ensure that all paint or other insulation is remove from around the hole area , and using self tapping screw, securely affix the bare wire ends to the vehicle chassis. Use as short as possible. * Many radio ' s and other music sources have an output terminal for connection of the remote turn on of the power ampli fier. CONN ECT the output terminal to the am plifier REM control jack. If a radio doesn ' t have a remote turn on feature , you can connect the RE M pole to external switch for positive + 12V ON / OFF. * To help minimize interference, it is best to run the Dower cables along the opposite side from the audio cables . Caution : The power cables must be connected tightly. A loose connection may cause malfunctions or interference noise or distortion. 2 SLA VE Subwoot..
