I remember. I think I finally fell asleep on the third page or so.
Thanks for the link.
I was thinking of using a mono sub for my 4ohm DVC 8s, so I could use the rear channels of my 4ch amp on the 6.5" mids in my rear doors.
So, I'd want to use just a single VC of each sub in series to the mono amp for a total 2ohm load. And, since they're free-air I remembered some of your earlier comments about changing woofer specs with the undriven VC.
Any easy ways about figuring what resistors I'll need or should I attempt to tune by ear?
