Impressive! Curious to know what difficulties you encountered replacing the hookup wire. The run from the coax board to the coax looks problematic to me. Some questions:

Was your OEM wire in a tube, sealed with hot melt?

How did you guide the new coax wire from the coax chamber through the fiberglass and around the brace above the woofer?  

How did you seal the new wire at the hole where it enters the coax chamber?

Finally, what gauge is your new wire and did you have any problems fitting it into the hole on the driver tab?

How did you seal the new wire at the hole where it enters the coax chamber?

That would be a challenge since I assume the coax chamber has to be sealed from the bass compartment.  If there is any leakage, it will affect the sound of the coax driver.

My guess is you have to cut the existing wire, then run your own wire through the existing opening, then seal it with some type of weather sealant from Home Depot. 

Finally, what gauge is your new wire and did you have any problems fitting it into the hole on the driver tab?

It looks either to be 14AWG

or 12AWG:

But I am not sure how he run the ground wire.  Speaker wires usually do not have any grounding terminal so I would guess it has to be modified afterward.

Used Google translate to write this so hope it's all clear to you guys.

The diameter of the Supra Ply 3.4/S cable outer sheath is 8mm, I have removed the plastic tube that contained the coax wire and the existing holes are then drilled to 8.5mm with an angle screwdriver, where the cable enters the coax chamber I glued it with a PU TIX Express from Bostik, first I have the cable extended further then glued and then retracted the cable thru the hole again so that the hole itself is also provided with glue, immediately afterwards I sprayed some water with a plant spray to accelerate the drying process, later I tested the closure by pressing the passive woofer with a good result, totally no movement at the coax, the remaining holes are also drilled to 8.5mm so that the wires are supported there too, this time without glue.

The Ply 3.4 / S cable has two 3,4mm2 (OFC) cores, these cores are far too thick to fit into the holes of the coax and woofer terminals, these are soldered neatly direct on the plus and min terminals, the terminal supports of the coax and the woofer are attached to the units with a bolt, the earthed wires are secured to them so the frames are also grounded.

I have placed the gold plated earth terminal airtight through a 3mm hole between the two +/- connections, at the rear is a thin gold plated solder plate fixed to the m3 bolt.
