I'm gonna guess low to mid 140's. What you hear, and what the term lab tells you can sometimes be two totally different things. I have two DD9917's in a wall on a Z1 at 2 ohm (about 2000 watts, other amp blew only option for the comp) and pulled a 147.3 at the driver headrest =/ I though just from hearing it that it was a 150 easy...

Another example. about a week or so after that comp, a friend of mine got 4 RD alpha 15's in his honda element...which sounded to the ear a HELL of a lot louder then my setup...he was only able to pull a 146 even at the headrest, and a 149 at the dash.

But you still have to think though your box design could be 10x better then mine and my friends which could put you up there pretty high.

All you can do is meter it, adjust, meter, adjust, and meter some more.

I havn't heard much RE stuff, but I like your build, it looks nice and clean. Good job =]

tuning plays a big factor in this too, lower tuning seems louder so his 146 at headrest could have been at 30hz w here your 147.3 is at 42hz
