Alright, I modeled this with linearteam after running across another thread. Looks like it will be -8db @ 30hz. I am not sure if this will be acceptable when you include cabin gain in the car. Or if it just looks awful.

not a cheap performer

when I first bought the QT305,I was just looking for a low to moderate priced replacement for my 2.5 cu. ft. box. I installed the QT305,a 3in. id.x7.0 in. vent tube,and a 250 watt sub amp. The end results were way beyond my expectations. Even at moderate power levels the woofer gives a awsome performance.

IB setup with a pair of 12" woofers in my 240sx ala Scott Buwalda's car. Essentially I am willing to give up no trunk space and am looking to pick up the low end that the 8" woofers in the door leave off. I can get Image Dynamics woofers at cost through a friend, so Ill likely do that.

Thanks!

Yeah, the FI and the AE's are awesome. The main reason I am looking at IDQ's is because I can get them at a very reasonable cost. There was a guy locally selling a pair of 12" kappa perfects which we were unable to come to an agreement on price with.
