how to mire up 6x9"s?

[spitfire123]

hi all,

going to put some 6x9 in the parcell shelf of my fiesta..i was just wondering how to wire them up?

i currently have 2x 5.5" fli Speakers in the door cards that i want to use with them.

but how do i wire them up?

do i just use the same wire going to the front Speakers? like just spline it so 1 wire splits in to 2 wires and run the 2nd wire to the back of the car to my 6x9s and leave the fronts how they are?

cheers all
