I haven't measured the airspace of the dash pods yet, but it's sounding like it might need to be bigger. The 4.5" Seas are high passed at 160hz and the bottom end of vocals are much to prominent than the rest, even after -6db cuts
The spec sheet shows a nice curve with the driver in a 2.5 liter sealed enclosure, so I'll aim for that.

I have two options I can think of without needing to build new pods (which I probably should because they don't look the best... ...if I do rebuild, I'll try tweets in the sails and midrange in the same location, slightly more on axis.
1. Vent the pods into the dash. The pods currently sit on top of the OEM speaker location to vent to.
2. Use a uniseal and add a length of PVC pipe to gain the additional desired airspace that routes thru the OEM speaker location


Technically, I supposed I can try #1 first then add the pipe if the venting doesn't work out. I'm really liking the punch/kick/attack of the sealed pods, so I'm leaning to staying sealed.
Testing to come...
