every speaker and amplifier connection . The supplied speaker wire has a white 
stripe to indicate the (+) positive conductor .

termination
The woofer uses an angled locking screw connection integrated to the basket of 
the speaker . The tweeter wires are terminated with molded connectors (male and 
female) .  Use  the  supplied  wire  with  insulated  connectors  to  extend  the  tweeter 
wires  to  the  crossover  section .  Alternatively  you  may  solder  the  tweeter  wire 
connections and insulate them with high quality heat shrink tubing .

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 . Use the supplied template to 
help you locate and mark the holes needed to install the speakers .

If the planned installation location is in a door panel, be sure the speaker will not 
interfere with the window lowering mechanism . Ensure that the speaker wires are 
positioned to clear all moving parts inside the door .

For each woofer you will need to cut one large hole and drill small holes around 
the circumference . If the mounting surface is covered by carpet or fabric, use a 
knife  or  razor  to  cut  the  material  away  from  the  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 . 
Pull the wire through the installation hole and attach the terminals on the ends 
to terminals connections on the speakers . refer to the speaker wiring section of 
this  manual  and  the  wiring  diagrams .  Push  the  wire  back  into  the  area  behind 
the  installation  location  and  be  sure  it  will  not  interfere  with  the  speaker  or  get 
snagged by any mechanisms in the area .

Attach  the  supplied  foam  gasket  strip  to  the  mounting  surface  of  the  speaker . 
This  will  ensure  an  air  tight  seal,  which  is  required  to  achieve  the  best  bass 
performance .
