    features Molded woofer basket - The backbone of any good woofer is its basket. It provides the proper alignment and support structure for the magnet and moving parts while the very thin braces guarantee a minimum of early reflections off the basket that would be ordinarily transmitted as sonic colorations through the cone. Woofer cone - Anodized aluminum cones provide the perfect combination of rigidity and low moving mass for ultra-low distortion and superior transient response.

  • Page 4: Installation Planning

    Never run wires outside or beneath the vehicle where they can be snagged by road hazards or the moving parts of the vehicle. Use existing wire channels, sills, panels and molding strips inside the automobile to hide the wiring for neat appearance and safety. Make sure your radio/cassette/cd player and or other equipment is turned off while connecting the speaker terminals.

    crossover features and connections Tweeter Thermal Breaker Midrange Contour Switch Parallel Bi-amp Switch Woofer Tweeter demo Midrange Contour switch Positions of Demo or Car are provided to offer different contours to midrange woofer frequency response. This switch should be left in the Car position for most applications. Bi-amp/Parallel switch Select the Bi-amp position if you intend on driving the woofers and tweeters with separate amplifiers (four channels).

  • Page 6: Speaker Wiring

    To bi-amplify the system you will need two stereo amplifiers (or 4 amplifier channels) with one pair of channels to drive the tweeters and one pair to drive the woofers. You may also Bi-wire the system by connecting the woofer input terminals to the amplifier and connecting the woofer input terminals to the same amplifier with another set of speaker wires.

    holes to be cut. This prevents material or fibers from becoming tangled in the drill bit or cutting blade. If you are using the packaged metal screws provided in the hardware kit, drill the four speaker mounting screw holes with a 1/8"(3 mm) drill. Clean the work areas of all filings and shavings with a vacuum cleaner before you proceed with woofer mounting.

  • Page 10: Crossover Installation

    crossover installation The system supports conventional wiring, Bi-wiring or Bi-amping using the supplied passive crossovers. While conventional (parallel mode) wiring will provide excellent sound, bi-wiring or bi-amping may further enhance the performance in no-compromise systems. Bi-wiring uses a separate pair of speaker wires for the high frequency and low frequency signal between an amplifier channel and its associated crossover network.

    crossover connections and input switch setting Route the wires connected to the input terminals on the crossover network to the power amplifier. Connect the wires to the amplifier outputs as recommended by the manufacturer of the unit. Make sure there are no stray strands of wire which could cause a short circuit. Observe left/right polarity markings. Amplifer NOTE: In this configuration, you may connect the amplifier (+) positive to either the tweeter (+) or woofer (+) terminal, and the amplifier (-) negative to either the tweeter (-) or woofer (-) terminal.

  • Page 12: Bi-Amplified Connections To Crossover

    bi-amplified connections to crossover Connections from the crossover to the woofer and tweeter are the same as the normal wiring method. Connect the amplifier you have chosen for the tweeter to the “Tweeter In” terminals input. Connect the woofer amplifier to the “Woofer In” terminals. NOTE: You must move the selectable switch to the Bi-amp position.

  • Page 13: Bi-Wire Connections To Crossover

    bi-wire connections to crossover Connections from the crossover to the woofer and tweeter are the same as the normal wiring method. Connect the amplifier to the tweeter input terminals with one run of wire. Connect the amplifier to the woofer input terminals with another run of wire. NOTE: You must move the Bi-amp/parallel switch to the parallel position.
