Where to mount an Amp?

Arite, after much thought and mind changing, i finally have the idea for my system. so far i have a single 12" going in a box (a friend is making for free, to get practice, hes very good actually) in the trunk. Im going to make a rear seat delete. Thats where im monting the amp, NO wires will be visible. My question is, should i mount the amp on the bottom peice (where your ass would go is there was a seat) oe the bottom peice (where your back would go if there was a seat)? this is the last detail im strugglin with! thanks again guys.
 
not sure what you are talking about. if you are doing a rear seat delete the amp mounting location wont matter, it will look like crap either way. do you have a hatch? if so, the spot on the back of the backseat between the back panel is the best.
