What's wrong with my subs?

Question

I bought Rockford Fosgate 12" P1 subs about 2 months ago but recently they haven't been working that well. They're running on a Sony Explode 800W amp and I checked all the wires, which seem to be in the right place and working, but you can't hear any bass coming from the subs. I can see and feel the subs moving a little when I'm next to them, but when im sitting in my car I don't hear any difference whether they're on or off. Could they be blown and still be able to make the little movement that they make? Or could I have just blown one of the two fuses in the amp?

Answer 1

well you can easily check to see if your subs are blown....just push down on the center of the subs and if you feel and hear a crunch, then you've blown them....but i dont think they're blown with only a 800 watt amp unless your subs are less than 400 watts a piece.
