subwoofer with uncertain single or dual ohm

[drwang 10+ year member]

I was given this mtx blue thunder 12" subwoofer and I think it is dual 2 ohm however I've never seen this configuration before. Would someone please confirm or correct me on this? Also, I can't tell how to identify how to wire this up as a 4ohm load with this configuration. Thanks.

I'm bettin' it's a single 4 ohm woofer... only way to be sure is to get a dmm and test it.

Its definitely not a dual voice coil since there's only one terminal
