featur es Molded woofer basket - The backbone of any good woofer is its basket. It provides the pr oper alignment and support structure for the magnet and moving parts while the very thin braces guarantee a minimum of early reflections of f the basket that would be ordinarily transmitted as sonic colorations through the cone.
When removing or installing the grilles, be car eful 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 destr oy the unit. Never run wires outside or beneath the vehicle wher e they can be snagged by road hazards or the moving parts of the vehicle.
cr ossover featur es and connections Bi-amp/Parallel switch Select the Bi-amp position if you intend on driving the woofers and tweeters with separate amplifiers (four channels). Select the Parallel position if you intend on driving the woofers and tweeters with the same amplifier (two channels).
Y ou 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 fr equency cabling to be used for the two separate signal paths.
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 requir ed to mount the woofer .
Install the tweeter into the extension housing by first threading the tweeter wir es 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 dir ection, typically towards the listener’ s ear location. Surface mount The preparation of the mounting surface for the tweeter involves drilling thr ee holes.
Check the intended installation site to be sure that there is suf ficient depth behind the mounting surface for the rear cup and mounting screws. The minimum depth r equired 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.
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.
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 thr ough the holes in the crossover unit, and tighten them until the assembly is firmly in place.
bi-amplified connections to cr ossover Connections from the cr ossover to the woofer and tweeter are the same as the normal wiring method. Connect the amplifier you have chosen for the tweeter to the “T weeter In” terminals input. Connect the woofer amplifier to the “Woofer In” terminals.
bi-wir e connections to cr ossover Connections from the cr ossover 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.
