Combined with the experience of a professional installer, these safeguards provide enough detail to successfully complete an installation. If you do not have the necessary skills, do not install the amplifier yourself. Instead, see your authorized Clarion dealer for installation recommendations. MOUNTING PRECAUTIONS Although the Clarion APX200. 2M incorporates 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 and is isolated from the marine environment. For easy system set-up, mount the amplifier so the front panel controls will be accessible after installation. For the most efficient cooling, mount the amplifier so cool air runs along the length of the fins rather than across them. Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines, 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. 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 vessel battery to minimize resistance and avoid noise problems. 7 APX200. 2M Power System Amplifier 5. Add an external fuse on the amplifier's positive (+) power lead and connect it as close as possible to the vessel's (+) battery terminal. [. . . ] Check battery and ground wiring at amplifier; also check battery connections. Check speaker continuity to ground, it should not show a common ground. Check location for adequate ventilation; consult an authorized Clarion Audio Dealer. 11 APX200. 2M Power System Amplifier Problem Distorted audio.
