Thanks for all the info.
I also got an RSD to compare. I might put it in my wife's car (sedan, I got a hatch back). Much higher power handling than the IDQ...
I am curious about the Treo but I believe it has a deeper mounting depth (5.5" & recommended enclosure >.8 cu/ft.)
I went back to try the CVT and AGAIN, the installer told me they do better in a larger box...powerful sub tough...
Shame AA didn't publish the mounting depth. I called the site that sells them but they didn't know what it was either...I read a bit on them & seems like they use pretty fancy tech even in their low end Subs...what was their story with Adire?
