[What do you think of butyl rope?]

GM used butyl rope between the door and the weatherproofing layer beneath the door panels on older (60-80's) models from what I've found. It seemed to serve as a seal for the plastic sheet to keep water from coming in the vehicle through the door as well as preventing the door panel from rattling on the door.
I took the original rope off the doors of my elk when I was cleaning up the metal and there was a very noticeable difference in the amount of rattle (plastic on metal) that was audible.

[Metered your Skar Audio System? Let's see scores!!]

Did a 137.9 @ 30 hz on the dash and a 138.1 in the kick with one VVX10 v1 on a DD SS1a at 2 ohms. I'll get a pic at the next meet.
Build is in sig for anyone interested.

[What version SA-8 do you have ?]

Interesting to know that I have a v1.75; thought it was a 1.5 since the day I got it as a replacement.

I realize it's a little off topic, but would the softer spider of the 1.75 cause the Fs of the woofer to be slightly lower than the v1/1.5? Trying to find a legitimate reason to rebuilt my transmission line.
