The Depth Really depends on if you want to mount the amp behind it like I did or not. My sub requires a mounting depth of 5.5" and has room to spare. The 10W6v2 requires 6.9". My "Dome" is 8 Inches in Depth, So it would be a pretty tight fit if you mounted the amps behind it. Without mounting the amps, you should be able to get an 11" dome, and get the air space you need.

 

Update:

I Removed the two Rockford Amps and Installed a single 4 Channel Clarion Amp. MUCH better sound quality from the Clarion, I highly recomend them.
