User manual AUDIO DESIGN R250-1

[. . . ] Congratulations on your purchase of the world's finest brand of car audio amplifiers. At Rockford Fosgate we are fanatics about musical reproduction at its best, and we are pleased you chose our product. Through years of engineering expertise, hand craftsmanship and critical testing procedures, we have created a wide range of products that reproduce music with all the clarity and richness you deserve. For maximum performance we recommend you have your new Rockford Fosgate product installed by an Authorized Rockford Fosgate Dealer, as we provide specialized training through Rockford Technical Training Institute (RTTI). [. . . ] For easier assembly, we suggest you run all wires prior to mounting your unit in place. Route all of the RCA cables close together and away from any high current wires. Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any vehicle. never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection. ALWAYS protect the battery and electrical system from damage with proper fusing. Install the appropriate fuse holder and fuse on the +12V power wire within 18" (45. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall. Use high quality connectors for a reliable installation and to minimize signal or power loss. When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good, clean ground connection. Grounding connections should be as short as possible and always be connected to metal that is welded to the main body, or chassis, of the vehicle. Seatbelt bolts should never be used for connecting to ground. Engine Compartment Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will void your warranty. Passenger Compartment Mounting Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount of air for the amplifier to cool itself. If you are going to mount the amplifier under the seat of the vehicle, you must have at least 1" (2. 54cm) of air gap around the amplifier's heatsink. Mounting the amplifier with less than 1" (2. 54cm) of air gap around the amplifier's heatsink in the passenger compartment will not provide proper cooling and will severely affect the performance of the amplifier and is strongly not recommended. Amplifiers will put an increased load on the vehicle's battery and charging system. We recommend checking your alternator and battery condition to ensure that the electrical system has enough capacity to handle the increased load of your stereo system. [. . . ] Allows you to conveniently switch the output phase of the amplifier between 0° and 180°. This is an adjustable Bass level control centered at 45Hz @ 12dB/octave. When connected, the "Gain Control" is linked and allows you to remotely control the output level of the amplifier from the dash or center console. Find a location, either under the dash or near the center console, that gives easy access to adjust. [. . . ]
