Well the sub. Did you connect the RCA hookup for sub out? Antenna lead for the amp turn on(blue wire) Fuse good to the amp? speaker hooked up inside the box? (Dumb i know, but happens)

Oh ok, you have the stock 8" sub. It was powered off your old deck. I'm not overly sure about how itll work now. Call your local car audio shop
