Sub Terminals, eclipse 12''

dielon, forget about taking a picture.  Post the model of the Eclipse sub you are talking about.  If it is a dual voice coil sub, it will have pos and neg inputs for each coil.  When this forum knows the model, we can look at the sub.  If you have a manual, read it.  If you don't understand it or don't have one, you can get one online.

For pos and neg, usually there is a + and - on or near the terminals.  Or there may be a red or purple dot near the positive terminal.  At any rate (and ignore this if what I say here is too confusing) you can use either of the terminals for pos, and the other for neg.  AS LONG AS you are consistent with all coils on both subs;  that is to say, you can label them yourself as long as you make each sub identical.  Then wire according to the diagram.
