I got a 10" Pyle subwoofer. Its just sitting here collecting dust. It's 500watt and 4 OHM. It sounds decent. I had it in my truck for a small length of time and in my Geo Metro for 4 days. It hits pretty good. It's the perfect bass but I wanted something that hit a little harder. Ill let it go for $35 plus a small amount for shipping depending on your location.
