Joe X Posted August 20, 2012 Report Share Posted August 20, 2012 .6 cu frBox 31hz, sub sa8v1.5, 730 Rms tuned with DD-1 SQ track. Great specs but not that, the external dimensions of the box, the dimensions of the port (H;W;L), the model of the amp. Link to comment Share on other sites More sharing options...

jhmeg2 Posted August 20, 2012 Report Share Posted August 20, 2012 .6....... um, for an sa8? I'm not an expert, but I think you need a bit more air space. The sub itself takes up a bit of that in its self. But its motoming out, and there are standing waves inside the box. you can see it affects the cone, do you see how the cone ripples.... thats not good. if you can, try some polly fill. and at low volume, see what the impedence rise is before, and after. If you see a noticable decreese, the box is to small, and your choking the sub. again I'm not an expert in sub=enclosures, I'm just a rocket scientist. ////Alpine, Eclipse, Load Boss, Pheonix Gold, MB Quart,Digital Desings, Memphis, Stinger, Periphial, MTX, Visualogic Link to comment Share on other sites More sharing options...
dkahns51 Posted August 20, 2012 Author Report Share Posted August 20, 2012 It makes the sound holding it in air too I just can't film it when I do it. .6 is plenty of room for the sub. The ripple effect you are seeing is the camera effect.. It can't pick up the motion of the sub. **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time Link to comment Share on other sites More sharing options...
