Ive got a Pioneer compact 10" sealed downfiring behind the drivers seat. Its pretty good, but it gets a little peaky once it crests ~65hz or so. I think its just a simple matter of a 10" driver having .35 cu/ft of space.

Since I dont use the space behind the drivers seat, Im thinking about getting a single 12" and building a box for it. The only thing is, I need a 12 that can handle 400watts and has a single 4 ohm voice coil. My class D amp is only 4 ohms stable when bridged.

Of course, I also want to get a tweet amp so I can finally run the DEH80PRS active.

Decisions decisions...
