Beautifully designed and built. I particularly like the rear seat fold-down 'arm rest' that reveals the single Type-R sub, and the PXA mounted in the roof.
The RCA cables are presumably quite long, passing from the PXA to each amplifier. Does this bother you? I would prefer to have short RCA cables, and maximise the use of the digital connection between the D800R and PXA. I am of course being very critical, because there is nothing else to fault!
Other details are excellent, like the Techflex braiding on wiring, metal trim pieces, and custom front tweeter pods in the sail panels.
