User manual AUDIO DESIGN P500-1BD

[. . . ] 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). [. . . ] Route all of the RCA cables close together and away from any high current wires. Use high quality connectors for a reliable installation and to minimize signal or power loss. 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. 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. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall. 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. 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 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. Stock electrical systems which are in good condition should be able to handle the extra load of any Punch Series amplifier without problems, although battery and alternator life can be reduced slightly. To maximize the performance of your amplifier, we suggest the use of a heavy duty battery and an energy storage capacitor. CAUTION:If you do not feel comfortable with wiring your new unit, please see your local Authorized Rockford Fosgate Dealer for installation. Keep RCA cables close together but isolated from the amplifier's power cables and any high power auto accessories, especially electric motors. This is done to prevent coupling the noise from radiated electrical fields into the audio signal. When feeding the wires through the firewall or any metal barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this point to adjust for a precise fit at a later time. NOTE:We recommend a 4 AWG wire for use on the power (B+) and ground (GND) connections. Prepare the RED wire (power cable) for attachment to the amplifier by stripping 5/8" of insulation from the end of the wire. [. . . ] Check for proper speaker connections and use an ohm meter to check for possible shorts in the speaker wiring. If the noise is eliminated, connect the REMOTE lead of amplifier to source unit with a delay turn-on module. If the noise is eliminated, use a relay to isolate the amplifier from noisy turn-on output. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires. [. . . ]
