[. . . ] Failure to do this means you're a few brews short of a 6-pack and you probably already acquired the nickname of "Sparky" or "Smokey". Do NOT hook the ground cable back up to the battery until the rest of the wiring is complete. Factory ground wire may need to be upgraded, especially if it is smaller than the power wire, frayed, or broken. Positive battery terminal Fuse must be installed within 18" of battery. Run signal cables (RCA) and remote turn-on lead down the opposite side of the vehicle of the power wire to avoid radiated noise. Drill a hole in the firewall & use a rubber grommet to keep wire from shorting. Run the cables under the carpet near the side of the vehicle. Avoid sharp edges that could chafe through the insulation. Ground cable to bare metal chassis/ frame with nut & bolt. No screws or seat/seatbelt bolts! <7> TERMINALS * Power terminal block & Speaker terminal block for PC360. 2 / S580. 5 * Power terminal block & Speaker terminal block for PC400. 4 / PC640. 4 * Power terminal block & Speaker terminal block for PC1000. 1 * Power terminal block & Speaker terminal block for PC740. 5 <8> CONTROLS * Crossovers for PC360. 2 / S580. 5 * Crossovers for PC400. 4 / PC640. 4 * Crossovers for PC1000. 1 * Crossovers for PC740. 5 <9> Control Definitions Alrighty, here comes the fun stuff. [. . . ] We're going to break this down to it simplest form so that there is no way you can possibly do any damage in the installation process to your audio system. We're going to explain in detail how every single knob and switch work rather than turn you loose on a sophisticated amplifier and have problems. You MUST use a fuse holder or circuit breaker within 18" of the battery. All cables ran through the firewall must be protected by a rubber or plastic grommet. If you have multiple amplifiers, the main fuse or circuit breaker at the battery should be the sum of all fuses or slightly less. Connect to the amplifier output or power antenna output of the source unit. If the unit does not have a switched +12V output, you can use another switchable +12V. Crossovers These controls allow you to pass and block frequencies to each driver. LOW PASS ­ This control allows you to pass only frequencies lower than the frequency you choose to the drivers. For example, if you are powering a sub woofer and you choose 70Hz, then only 70Hz and lower tones will be passed through to the subs while all unwanted higher frequencies above 70Hz will be blocked. A lot of head units have 4 volts of signal voltage which mean that your control would be set in midway through the range. If you happen to have a line driver (signal booster) that yields 9volt or more, you will set the gain at the minimum position. In all of these examples, when properly level matched, the amplifier will put out full volume. Setting the control above the proper point may cause damage to the amplifier and speakers, and can result in poor sound quality and overall undesirable results. . . If you do not know what goes here, get over to your local PRECISION POWER dealer immediately!Balanced Signal Inputs ­ Using our BLT Balanced Line Transmitters, you can achieve balanced, noise-free signal transfer. This is a MUST and no-brainer for any audiophile, sound quality competitor, or anybody serious about their music. CH1&2 Signal Mode ­ There are two options here for the signal processing. You can either choose CH1&2 HP/FR for High Pass or Full Range operations, or you can choose COPY CH3&4 making channels 1&2 receive the same processing as channels 3&4. This is handy if you want channels 1&2 to be identical to 3&4 or if you need low pass or band pass signal. [. . . ] This is handy if you want channels 1&2 to be identical to 3&4 or if you need low pass or band pass signal. Understand that this bypasses EVERYTHING so that the front channels are identical to the rear channels. Phase Switch ­ This switch changes the phase of the woofer from 0 to 180 degrees. Subsonic ­ The Subsonic Filter protects your subwoofers from playing frequencies below the physical limitations of the woofer, or that are beyond the human hearing capabilities. [. . . ]
