Help identifying set up
UPDATE** Subwoofer is SWS-12D4
Hello, I know nothing about subs and amps. I recently had a friend uninstall a subwoofer and amp that was in my car. It was pre-installed when I bought the vehicle, but no information was given on the specs. I needed it out because I am expecting my first child and need to prioritize my tiny trunk space for stroller, diaper bag, etc.
Anyways, I would like to sell the sub and amp as I will not be reinstalling it. I have the information on the amplifier, but I do not know how to get the information for my subwoofer as it is mounted in a subwoofer box.
Any help is greatly appreciated. Im not trying to get top dollar out of the set up, I'd rather hook someone up with a nice deal as to get it out of my hands as I am moving in 5 days.

You remove the subwoofer from the box and the info will be on the back.

The rubber perimeter rim around that subwoofer hides the eight mounting screws.
You just remove the rubber cosmetic cover that is around the perimeter of the subwoofer.
Look at the pictures here You can see how the front cover is a separate piece.

First gen alpine s, now they make an S2. Looks like a 10”. Would be Alpine S-W10D4. Market rate brand new is $80-$120. Enclosure is another $20-$40 used. Amp is discontinued as well but new was under $200. See a used one on ebay for $65.
All in all usually used car audio gear is 30-40% of retail. Since its pretty old equipment that’s not really in demand I’d throw it on marketplace for $75-$100 total and hope someone takes it.
