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. Vented voice coil - Ma

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. Make sure your radio/cassette/cd

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. Be sure to connect the positive crossover terminals to the positive speaker terminals and positive amplifier ter

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. U

Check the intended installation site to be sure that there is sufficient depth behind the Metal mounting bracket mounting surface for the rear cup and mounting screws. The minimum depth required behind the back of the mounting surface is 1" Mounting slots (qty 4) (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 M4-0.7 x 4-1/2 cm the rim of the cup will completely cover the

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. Bi-Wired
