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 polypropylene provides the right combination of rigidity and low moving mass for low distortion and excellent frequency response.
When removing or installing the grilles, be careful not to brush the woofer's rubber surround or the tweeter's dome with the edge of the grille. Cutting or tearing the surround or dome will destroy the unit. 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.

Select the Parallel position if you intend on driving the woofers and tweeters with the same amplifier (two channels).
You may also Bi-wire the system by connecting the woofer input terminals to the amplifier and connect ing the tweeter 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. See Crossover Installation for additional information on bi-wiring.
speaker installation Woofer installation The woofer will fit into many standard factory mounting locations using the existing mounting holes in the automobile. Remove the trim panels and inspect the installation locations before you cut and drill the holes required to mount the woofer. Removing the panel will also make it much easier to route wiring inside the door. Look for original equipment speaker installation cutouts that can be used to install the woofers with little or no modifications.
Install the tweeter into the extension housing by first threading the tweeter wires through the extension housing and then installing the tweeter into the mounting slots of the housing and turn the tweeter counterclockwise to lock the tweeter in place.

The tweeter is mounted at and angled relative to the woofer. Before final woofer mounting, rotate the woofer so that the tweeter is pointed in the desired direction, typically towards the listener’s ear location. Surface mount The preparation of the mounting surface for the tweeter involves drilling three holes. Two holes are for the mounting screws. Their centers must be spaced 15/16” (24 mm) apart. Use a 1/8" (3 mm) drill bit for the supplied screws to mount the cup.
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). The front cup mounts into the mounting through a 1-7/8" (48 mm) diameter hole. Be careful that the hole does not exceed 2-1/8" (55 mm) diameter at any point so that the rim of the cup will completely cover the edge of the hole.

Tweeter Bolts Tweeter Wire Panel Flush Mount Housing Bracket Wiring NOTE: The tweeter grill can be easily removed for coaxial applications, or to facilitate mounting the tweeter behind an existing factory grill. 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.
Align the mounting holes in the bottom half of the crossover unit with the holes you have drilled at the installation site. Pass the four #6 x 1 1/4" screws through the holes in the crossover unit, and tighten them until the assembly is firmly in place. As before, do not over-tighten; this is especially important if the mounting surface is not perfectly flat. After all the connections and any necessary adjustments have been made snap the cover back in place.
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 selectable 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.
