actually I think he is saying it right... but depends if he's pulling the whole port out of the box and keeping the length but outside the box... you know the extra airspace in the box causes to tune lower

then give me dimensions of the lagest box that can fit in your trunk
Will do. Once I took the lvl 5's out of my old box no more surround rippage lol I will indeed be getting smaller motors but they wont be a step down. In fact the new motors are as strong as the 99z's.

What u need if u stick with 10's is a long throw motor but no more than 7" or so in diameter. Do u have room for a single 15" ?

Looking good Rob

Been following this on CA, Termpro and here for what seems like ages and i have been waiting to see you try this setup (center aero), lot less port area but it should help with the loading issues and with any luck get you even louder.

How about some more pictures?

This time around I'm making a vanity plate for the face of the box and one for the trunk opening. We're gonna shoot for breaking 50's at 36hz while looking good lol
