fiddly for big rugby playing fingers but no real probs,
undo some dash, feed cables down around gubbins from unit slot ( remember to keep them even lengths), - use electrical cable with a loop in the end to locate an pull cables-
pull up trim in f/well. locate the rubbers on the sidewall of the footwell, poke hole thru, feed cable, remove door cards,( be carefull with the original plastic if any still present)
I removed the original little door tidy pull open trays, increased the remaining aperture to suit the cones I selected , using a round file it took seconds.
the sound is well balanced, that extra tin is appreciated up front
