[. . . ] These safeguards provide enough detail to complete the installation successfully. If you do not have the necessary skills, Clarion recommends consulting your authorized Clarion dealer for installation. MOUNTING PRECAUTIONS Although the Clarion DPX1001. 2 incorporate heat sinks and protection circuits, mounting the amplifier in a tight space without any air movement can still damage internal circuitry over time. Choose a site that provides adequate ventilation around the amplifier. For easy system set-up, mount the amplifier so the front panel controls can be accessible after installation. In addition, observe the following precautions: 1. For the most efficient cooling, mount the amplifier so cool air runs along the length of the fins rather than across them. Remember, any moving air will dissipate heat. Avoid mounting to subwoofer enclosures or areas prone to vibration. Do not install the amplifier on plastic or other combustible materials. Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines, brake lines (under chassis) or electrical wiring. WIRING PRECAUTIONS Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion dealer. Before installation, make sure the source unit Power switch is in the OFF position. Disconnect the negative (-) lead of the battery before making any power connections. When making connections, be sure that each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing. Failure to do so may damage your equipment. A secure clean ground connection is critical to the performance of your Clarion amplifier. Use the shortest ground wire possible and securely connect to the car chassis to minimize resistance and avoid noise problems. 9 DPX1001. 2 Power System Amplifier 5. Add an external fuse on the amplifier's positive (+) power lead and connect it as close as possible to the vehicle's (+) battery terminal. Use a fuse rated to the total current consumption of the amplifier(s). [. . . ] Review Installation and check all wiring connections. Problem Whining or ticking noise in the audio with engine on. Solution Amplifier is picking up alternator noise or radiated noise. Turn down input gain; move audio cables away from power wires. [. . . ]
