So, onto the Power. Really handy having the Battery in the front, it means that power runs are kept to an absolute minimum length. Keeping to the ethos that everything would be hidden - I didn't want to use the standard Amp location and decided a false floor would be the way to go, ensuring that the amps (one 4-channel and one 2-channel) were adequately cooled.)
So the component count is very simple: The two amps, a fused distribution block and a 1/2 Farad Stiffening capacitor. There is also a main fuse attached to the boot wall, approx 6” from the Battery.
The components were laid out on an MDF board cut to shape and then the cable runs decided on:

Then secured to the front boot floor:

I then templated and cut out a ‘floor’ from MDF, incorporating vent holes, a handle (made from Velcro) and a slot fan that shifts a surprising amount of air. This was then trimmed in black carpet -

(Can you see the face?!)
The final touch was to attach a luggage net to it and fit

And by filling in the holes left by the removal of the CD changer and amp, and attaching the warning triangle, I think it looks pretty stock:
