I have a pioneer premier 3001d2. Its being powered by a hifonics brutis 1610 amp wired @ 1ohm. I just built a box for it. It was 1.35 cubes, and the sub displacement was .181 so its about right on for the recomended portedbox. oh and the port is 3"x 3.5. It clips no matter what I do. I have 4 gauge wire throughout my truck and I cant get it to stop. I tryed wiring it @4ohm but my amp wont even tickle it. any suggestions? is my box screwed?
