I want to build a 4th order bandpass enclosure for 12" Level 3 but can't find specifications for it. Can anyone help me with this? Thanks!!!

All, I've been looking unsuccessfully to find specifications to build a 4th order bandpass enclosure vented into the cabin of my civic. The sub will be pushed by a JL Audio HD750/1. Front stage is Hybrid Audio Legatia L6's and L1Pro Tweeters running active off an HD600/4 processed by an MS-8. I also have a 10W7AE that I planned on running in a sealed enclosure but want to try the 12" Lvl3 in the BP enclosure to cut down on trunk rattles.

As is or do I need to strip them? Dumb questions I know, but having never worked with on a braided wire like that, I dont want to mess anyting up. I've soldered plenty before so I think I'll do it myself if thats all it is.

I received my 12” Level 3 and was super excited when I opened it up. It is an amazing looking sub. However, once I pulled it out of the box, I saw that the braided wires (tinsel leads??) that connect to the terminals were disconnected on both sides (both terminals). Is this normal? And if so, is it something I can fix.
