I dont think they would sound that good mate. I mean generally speaking subs should be boxed up in a suitable sealed box for best performance.
How do you plan on sealing them up ? There is not really that much room behind there hey.
I mounted my amps on some MDF above my fuel tank, they are out of the way and its all pretty neat. I mounted my 15" sub in a custom made box on the drivers side of the boot where you have your amps now.
Seems to work pretty well.
Anyways, keep us posted , its always good to see new designs

Noooooooooo, that will sound elcrapo!!! The amount of stuff that will rattle around back there is lots, not to mention that subs ALWAYS sound better in a box.
Your best option would be to (if you are still keen on twin subs) is to mount the subs where you have the amps, kinda against the fender/rear bar join and angle them so that they both point towards the cabin, ie angle them so that the focal point of the sound is in the cabin. Mounting the amps under the rear shelf is easy as, just cut some mdf pieces, and suspend them with some alloy straps.

The 2nd to last one is the option I'd be going for. Ideally you want them to focus on one point. Having them directly opposite to each other can cause turbulence where the sound waves meet.
Unfortunately, bass and boot space in a soarer can be a talll order at times, especially when keeping access to the spare. A single 12" in a well made box does wonders in a soarer, have you entertained that idea at all?
Having them on the 'wall' as in the pic with the alpine system (ie, in boxes) would be ok, just not straight onto that panel as is. In an infinate baffle (or 'free air') setup, it is designed as that, and INFINATE baffle. ie the best performance would come from a panel that extends forever in every direction. As that is not possible in the mortal realm, having it so that as little of the sound waves from the back reaching the front is the best option.
There are many problems arrising from mounting them like this onto that panel... 1 where the boot lid arms poke through is to much of a gap for air to pass 2 the panel is weak as all hell. As it sits so close to the fuel tank, reinforcing it from the rear is not possible, and doing so from the front would just look crap.
If you want, give me a buzz on the weekend and I can come round and run through a few ideas with you if you want?

mine is the last one.
Behind that sub all the bits that usually sat there including the old amp, plastic thingos etc etc were all removed and the whole thing was sealed with fibreglass.
It is a funny shaped enclosure as it goes all the way up the side towards the rear seat. There is a deceivingly large amount of space in those corners once you remove all the crap.

The second pic from the bottom is a nice setup, simple but looks very pro! looking to make something similar only amps will be on the sides with some storage space, still abit up in the air about it but I'll nut something out. Maybe a fibreglass/MDF combo. I'll keep you all up to date on how things are happening but currently I got so many things on my plate to do to the car it isn't funny! At least it's just sitting in the shed instead of being driven for the moment. Ripping out the side cooler to replace with FMIC, making a new BFI box from stainless courtesy of a mate, body work as well since I'm sick of the cheap ass bodykit on it, custom rear parcel shelf and the custom boot layout!

Oh yea as Ben has mentioned, never point the subs towards each other or directly at a flat surface as sound waves tend to 'bounce' back and are a main cause of distortion. Best off having them angled slightly and never directed at flat surfaces, this also applies for inside your box as well since a sub works both ways. Never aim the mag/basket at a flat surface where the soundwaves can bounce directly back. Also if your going to be placing them like that it's probably a good indication that your boxes for your subs arent going to be huge and will have a small air capacity so you may want to buy some speaker dampening cloth. The cloth will mask the actual size of the box making the sub think it has more volume than it actually does.
