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.
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. Turn on the various components and slowly advance the volume control ONLY after checking and double checking all connections.

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. This is sometimes done to allow a specific high frequency or low frequency cabling to be used for the two separate signal paths.
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. Woofer mounting Route the speaker wire from the woofer installation locations to the crossovers.
Flush mount (Surface or Angled) NOTE: Ensure that there is enough clearance within the interior door panel for the M4-0.7 X 4-1/2 cm (1.77 inches) flat head mounting screws. Reduce the length of the mounting screw as necessary to meet clearance. Check the intended installation site to be sure that there is sufficient depth behind the mounting surface for the rear cup and mounting screws. The minimum depth required behind the back of the mounting surface is 1" (25 mm).

Use the supplied black butyl material to attach the tweeter grill for all other applications.
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.
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. Failure to set the switch correctly may cause damage to the amplifiers or the 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. Failure to set the switch correctly will not damage the equipment, but could interfere with any enhancement of the sound due to bi-wiring.
