Amp mount suggestions?

[DJ_B_Easy]

NICO! Currently driving '08 Altima Coupe, finally installing my system. I purchased the Zenclosures box...

...to try and save some trunk space and keep it looking clean. My problem now is where to mount my amps? I need functional trunk space and dont want to lose the spare if I dont have to. Any suggestions as to where/how to mount the amps to keep my trunk functional and also not entail a TON of custom fab? Behind rear seats is no go because that pushes the Zen box out too far and defeats the purpose of looking clean.

Anyone done anything with this enclosure or another that can shed some light?
