Joe X Posted November 12, 2012 Report Share Posted November 12, 2012 So here is a suggestion: Enclosure Specifications: Fb = 32 Hz Vb = 2.5 ft^3 External Height = 16 in External Width = 34 in External Depth = 17 in Port Width = 3 1/4 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Top & Bottom (3 parts) = 34 x 17 Left & Right Sides = Side 1 = 15 1/2 x 13 3/4 Side 2 = 16 1/4 x 13 3/4 Front = 30 x 13 3/4 Back = 34 x 13 3/4 L Port Internal Assembly Parts: Front to Back = 12 1/4 x 13 3/4 Extension = 22 x 13 3/4 Assembly guide (generic dimensions): Any questions, let me know.

SCS_Audio Posted November 13, 2012 Report Share Posted November 13, 2012 W7's like big boxes. The bigger the better for them IMO. I had a 13W7 in a 5 cube box in my trunk with 2 slot ports. Sounded good and got loud. If you could get to 4 cubes after displacement and tune to around 32 as suggested by JoeX that would be good. WIth only 1000 watts on that 13, no box will be too big. With mine in a 5 cube box, I had a Orion 2500D on it at 0.75 ohm. A larger box will be louder and more efficient. It will also help with lows (35 and below). 2012 North American Street Stock Runner-up - 150.9 on 1800 clamped watts (Teammate)2013 dB Drag Street Trunk World Champion - 153.9 on 3200 clamped Watts (Teammate)2013 MECA Trunk 1 World Champion - 152.8 Headrest (Teammate)2013 MECA Park & Pound 2 World Champion - 130.6 (Teammate)Checkout our build and videos !! : ) 150+ Trunk Build Log itsgordy1 youtube channel (click for Hairtricks)Smith's Custom SeatsMartinsburg, PA (Second Skin Dealer) Link to comment Share on other sites More sharing options...
Nssuits Posted November 13, 2012 Author Report Share Posted November 13, 2012 What would be the differnce of running a 500/1 instead of the 1000 because I have a 500/1 1 as now and working at 1000 would the whole box change or would it be ok box for both 1000 and 500 Link to comment Share on other sites More sharing options...

I did have 2 JL 1000/1 on mine for a while. One on each coil. A single 1000/1 is enough to get this sub going, but no where near it's full potential. As your power increases, the general rule is you need to decrease your box volume. This is because a larger box has less control over the excursion of the sub. In your case, a single 1000/1 will have no problems even in a 5+ cube box. The X-mech of those things is pretty hard to hit. You just need to set your subsonic filter if you are scared of making it tap. 2012 North American Street Stock Runner-up - 150.9 on 1800 clamped watts (Teammate)2013 dB Drag Street Trunk World Champion - 153.9 on 3200 clamped Watts (Teammate)2013 MECA Trunk 1 World Champion - 152.8 Headrest (Teammate)2013 MECA Park & Pound 2 World Champion - 130.6 (Teammate)Checkout our build and videos !! : ) 150+ Trunk Build Log itsgordy1 youtube channel (click for Hairtricks)Smith's Custom SeatsMartinsburg, PA (Second Skin Dealer) Link to comment Share on other sites More sharing options...
