Cdizzle Posted June 10, 2008 Report Share Posted June 10, 2008 We have a rockford fosgate p1000-1bd amp running at two ohms to the p3 sub. The gain on the amp is a little less than half and infrasonic filter is off but we have also tried having it on without a difference. when the volume is turned up about half way on the stereo it sounds like the sub is bottoming out until you turn the volume back down. what would make the sub sound this way?

What kind of box is it in? Could be too big, or leaking bad.. Quote Check out StoneSounds to see my recent builds.Or look at the Flying White Facebook Page!

Cdizzle Posted June 10, 2008 Author Report Share Posted June 10, 2008 Well the box we built today, and it isnt leaking air that we can see around the box, except we did notice there is some air coming out of the front of the box where we cut the sub circle... The box is 1.73 cu ft, and I believe that the recommended was 1.79... Quote Damn Thiefs Link to comment Share on other sites More sharing options...
ISO Posted June 10, 2008 Report Share Posted June 10, 2008 1 P3 with a 1000 watts on it. It might have too much power on it. Is it ported or sealed?

ISO Posted June 10, 2008 Report Share Posted June 10, 2008 I guess sealed. I think you have to much power on it.

pstone11 Posted June 10, 2008 Report Share Posted June 10, 2008 Well, he has it at 2ohm which is 500 (probaly more like 700ish), and that P3 takes 500 RMS... I think maybe you should set the gains with a meter and seal that box up proper. Quote Check out StoneSounds to see my recent builds.Or look at the Flying White Facebook Page!

Cdizzle Posted June 10, 2008 Author Report Share Posted June 10, 2008 It is Ported... The gain isnt even half up... Quote Damn Thiefs Link to comment Share on other sites More sharing options...
ISO Posted June 10, 2008 Report Share Posted June 10, 2008 I'm pretty sure that amp does 1000 watts at 2 ohm. I'm checking now.

ISO Posted June 10, 2008 Report Share Posted June 10, 2008 My bad, it is a 1 ohm amp. Sorry. Quote Isobaric - Refers to the practice of coupling two drivers together to make them act as one.
