Homemade subwoofer

I had to see if I could make a subwoofer, so I used a pool noodle(the blue on top), a plastic laundry basket(the black off and around the the white dust cap), a pop can wrapped in 4 layers of 26 or 28 gauge magnetic wire) the spider I can’t remember what I used and the basket of the speaker with the magnet was a alpine r1 12 inch sub. Not anything other than a project to see if I could make a sub produce sound
