[. . . ] In addition, mount the amplifier on a stable, flat surface. Mounting amplifiers upside down is not recommended and may cause premature thermal shutdown. Do not mount any amplifier in the engine compartment. Amplifiers are not designed to endure the harsh environment of the exterior elements. Passenger Compartment If you are going to mount the amplifier in the passenger compartment, make sure you have adequate room for ventilation. The amplifiers have been designed to make under-seat mounting possible. When mounting your amplifier under a seat or similar area, keep a minimum of 1" of clearance around the amplifier for adequate cooling. Trunk Compartment Mounting your amplifier in the trunk provides excellent performance as long as you do not restrict the airflow around the heatsink of the amplifier. For optimal results, mount the amplifier with as much clearance as possible. This type of mounting will yield the best cooling due to the convection effect of the amplifier chassis. General Precautions and Installation Tips NOTE!Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines, vacuum lines, or electrical wiring when working on your vehicle. Disconnect the vehicle's ground wire at the battery before making or breaking connections to the audio system's power supply terminals. Failing to securely mount the amplifier can result in damage or injury, particularly in the event of an accident. An unmounted amplifier becomes 16 © 2005 Directed Electronics--all rights reserved a dangerous projectile in the event of a crash. Never mount the amplifier where it might get wet. Mount the amplifier so the wire connections will not be pulled. Route the wires where they will not be scraped, pinched or damaged in any fashion. The +12V power supply wire must be fused as close as possible to the battery terminal, ideally within 18". Use the recommended fuse size or circuit breaker listed in the Power Connections section of this manual. If you need to replace the fuse plugged into the side of the amplifier, replace the fuse with the same size ATC type fuse that came with the amplifier. If you are not sure as to the correct value, refer to the Power Connections section of this manual for details. Using a higher current fuse may result in damage to the amplifier that is not covered under warranty. Make sure all the equipment in the system is turned off when making or breaking connections to the input RCAs or speaker terminals. Turn on the system and slowly turn up the volume control only after double checking all wire connections. Power for systems with a single amplifier can be supplied by most automotive electrical systems. Systems with multiple amplifiers may require a higher capacity battery, alternator or the use of a storage capacitor. [. . . ] Check system with known work ing speakers and fix or replace as needed. Speakers are blown Poor bass response Speakers wired with wrong Check speaker polarity and fix polarity causing cancellation as needed. at low frequencies Crossover set incorrectly Reset crossovers. Refer to the Internal Crossover Configuration section of this guide for detailed instructions. Impedance load at amplifier Check speaker impedance load, is too low if below 2W, rewire speakers to achieve higher impedance. Battery fuse blowing Short in power wire or incorrect wiring Fuse used is smaller than recommended Check power and ground connections and replace or repair as needed. [. . . ]
