Help with a subwoofer

Hey guys, I have two p3d412 I got off of ebay each from a different seller and I've been having issues with one of them. I acquired it over a month ago and just was able to finally diagnose it now.

Well I think anyway. So I tested it by hooking it up to an amp and I'm not getting anything even though it works perfectly fine with my other one.

So I tested it with a multi meter by putting the positive on one coil and the negative on another coil and I don't get a reading however if I put positive on positive I get a reading and it jumps all over the place. Is the sub dead like totally or can I repair it?

Thank you

Do two tests, positive on coil 1 +, negative on coil 1 -. Remember to be in ohms mode. Then repeat for coil 2, post numbers

No reading and the cone makes a scratching noise when pushed down on it.

It's probably toast.

Recone is your only option I think. The scratchy sound is indicative of a fried voicecoil. If it's been less then 45 days the I recommend you file a paypal dispute against the seller. That's assuming he claimed the sub was in good working order when you purchased it.
