How can I vent the spare tire well?

Asked this once before, but no one's answered, so I'll try making it a thread.

Installing a custom sub enclosure (single 10", about 1 cu ft) in the spare tire well of an '05 Subaru Outback.  With it go 3 mid-sized amps.  It's all covered by the stock false floorhatch. 

The question is this - how do I vent those amps?  2 of them are class-A, so they're gonna get hot.  I'm open to any ideas & not afraid to be creative, but I need to keep the functionality of that area intact (no big holes in the floor to be covered by luggage, for instance) and it needs to be very stealth. 

Thanks in advance!

If the amps must remain in the spare tire well, the only solution I can come up with would involve cutting out some sheetmetal in the spare tire well and installing vents to the outside (like the ones inside bumpers).  Then you could install fans.  Also you could place luggage above them all day long and not worry about it.

It would be easier to build a sturdy false floor under which you mount the amps and have room on the sides to vent into the cabin.  Connect some fans, and you'll be just fine. 

Thanks for the input.  Someone else mentioned the bad juju I'd get from venting outside:  moisture + quality electronics = Tylenol-IV type headaches.

My thinking now is to use "channels" between the carpeting & metal underneath, one on each side, and force air in one, out the other, and have them vent to the very edges of the trunk space where it'd be hard to obstruck them.

When this idea proves impossible, I'll be back to cry for more ideas.  Meanwhile, still open to suggestions here...

People keep pointing me towards venting the hatch into the trunk, but I don't want to do that simply because those vents will be covered when I load up to roadtrip.  I think I've got it figured out using a couple squirrel cages & channels in the subfloor, it's pretty unique.  I have no idea if I can pull this off!  If I do, I'll put up some pics.

Frankly, this install will be the most challenging I've ever taken on - custom fiberglassing x2, wierd dash mods with springs(?!?), creative venting of class A's in small sealed spot, & all stealth - may take a month of spare time to pull off.  I guess I'll either be proud as hell or flat out ashamed of my failure, we'll see.

I've been replying to others' questions trying to give something back for my own, and behold I'm a Standard member now!  Hey, thanks to everyone for the input & time.
