Subwoofer and Amp mount ideas?

[ticopowell]

So i have my super cab 2005 F-150 and I have a 12" shallow mount memphis sub and 2 amps, 1 for the sub and 1 for the door speakers. I want to have as much space as possible without hurting the sub or the amps, so i was wondering if it is possible to mount the sub under the front center part of the front 40/20/40 bench seat with some modifications, and also my biggest question is if it is possible to put the amps behind the rear seat. I figure that this will give me the most room, and since the sub doesnt need a lot of space, if i can't put the amps behind the seat I can just put them under and then not use that area. Either way I still havent figured out how to remove it to see how much room there is, i assume ill have to pull the whole seat out to find out, but if anyone already has tried that or knows how to do it easily then please let me know. thanks
Also if anyone has any better ideas on how to put the rest of my system in there then please let me know!
