The Power Series T1D412 Dual 4-Ohm subwoofer builds on innovative new Rockford Fosgate technologies. Built for cars and trucks, these bad boys have patented VAST technology that increases surface cone area up to 25% so the T1D412 performs like a much larger woofer over the previous model. The new FlexFit basket not only looks the part but it provides extreme flexibility for extreme installations. Clean, high tech and ready to set off car alarms, the T1D412 is here!
