Please tell me if this JBL sub replacement is wired right

[Gavin S.]

before I button my rig back up. Sorry, I know there is a forum for this but obviously this one has a ton more traffic and time is of essence. Here's what I got. I did a bit of editing to illustrate what I think are indicators of which post is positive and negative. I attached the wires to my new sub (Rockford Fosgate P3SD2-8) based on this. There are two pairs of pos-neg posts on the new sub, one set for each voice coil, I assume. Any input would be greatly appreciated. Thanks.

The easiest way to test polarity is to tap a 9v battery on those terminals and see which way the speaker moves. If it moves out, look at which terminal the + side of the battery is touching and that's the + terminal.
