Subsonic Filter??
the NINE.2X does not have this.. do I need something on the amp for the 9kv.2s? like a 20 or 30HZ High pass so it will not play below that?
I should have my NINE.2x today. Probably will not install it until I figure out what the hell I am doing in the car.. LOL
I have a couple thoughts.. One being swapping my bostons ( at least the 1" and 4" with an Infinity set I have to see if it is better/worse)

I do not run a subsonic filter in the Vette. Did you get to see the 12Hz movement on the Infinity subs 
A subsonic filter is a must at the tuning freq (or higher) on a ported enclosure. Otherwise you can send the sub into defib
