amp installation options (opinions welcome)

[videsh 0]

hi all i have a sax 100.4 and a saz1500d ... i want to change my install a bit ... do something a bit more visually appealing

now in the pics below ud see one of the amps " floating " in the center ... i want to do a symmetrical pair like that

the lower board will have a small fan and it will have gaps in the board exposing the heatsink a bit

so now my questions

1 : has anyone ever installed their sundown amps in an area with minimal ventilation and did it have any issues ?

2 : do you think the setup will have adequate cooling ?

3 : what improvements do u think i can make?

The sides are wide open and the boards are not flush - ventilation should be fine.
