Gunbir, I did try the uhhhh... usual sources. Maybe a bit more looking around... :-)

vid6639, yes, I think I'll try something like that immediately. It tints can be avoided, nothing like it.

In fact I'm also going to try making a very light frame (maybe with the thinnest available aluminium 'L' rods) with regular speaker grille cloth (of good quality) stretched over it (the acoustically transparent type of cloth). I can then velcro this frame onto where the parcel-tray was (between the two vertical panels on which the amps have been installed). That way the stuff under it will remain hidden, the AC will still get to the amps, and I will still get the benefits of the sub firing into the cabin from the open boot. I'll probably get it done by somebody who knows his job rather than DIY (I want good and presentable finish). I'll chuck it if it doesn't look very good, though. If I can get this, all the related problems are solved. And, if I do want to show off the setup in the boot in the weekend outings, I can just remove this frame. A little bling never hurt anybody :-)
