Akslowroller Posted February 27, 2013 Report Share Posted February 27, 2013 I have built a few boxes and know there are several things to take into consideration. With that said I want something that will play low and put out decent spl. I am putting it in the back of an extended cab Chevy. I'm thinking firing forward and port firing up. But my main concern is port and box size. I will be running a Rockford T4000.1 on it. I know it's a little much but it's what I have. So just worried about building the box to spec with that much power. Any ideas would be appreciated. Link to comment Share on other sites More sharing options...
Joe X Posted February 27, 2013 Report Share Posted February 27, 2013 Post your max dims for a box, and guessing you are removing the backseat. Link to comment Share on other sites More sharing options...
Akslowroller Posted February 27, 2013 Author Report Share Posted February 27, 2013 My demensions are 48x20x20. My main concern is that sub should handle that power if I'm not super abusive. But I know I can build my box so that it will help save the sub some abuse. At least that's what I think I might be wrong. Who knows lol. I looked at FI's site the other day and it said 4-8 ftcubed. Now it says 4.5-9 what is the benefit of a smaller box compared to a bibber one. Also what will a smaller port do for me? I've been reading that 14-19 square inches of port is the norm, so just wondering what I should do Link to comment Share on other sites More sharing options...
Joe X Posted February 27, 2013 Report Share Posted February 27, 2013 Taking your maximum dims here is a suggestion: Enclosure Specifications:Fb = 34 HzVb = 6.3 ft^3External Height = 20 inExternal Width = 48 inExternal Depth = 20 inPort Width = 6 inCut Sheet List:* All Dimensions in Inches.* Wood Thickness is 3/4 for all Parts.External Enclosure Parts:2 x Front & Back (3 parts) = 48 x 20Left & Right Sides =Side 1 = 18 1/2 x 17 3/4Side 2 = 19 1/4 x 17 3/4Top = 41 1/4 x 17 3/4Bottom = 48 x 17 3/4L Port Internal Assembly Parts:Top to Bottom = 12 1/2 x 17 3/4Extension = 7 3/4 x 17 3/4 Assembly guide (generic dimensions): Important notes:- The port needs 6" of free airspace in front of it for proper operation.- Setting your amp subsonic filter to 28Hz is suggested.

Joe X Posted February 27, 2013 Report Share Posted February 27, 2013 Sweet man. Thanks for the quick response. I will give this a try and see how she does. I will update the visual to show bracing and all, anyways if you are too near the front seats maybe port/sub up would benefit you, take a look.

Akslowroller Posted February 27, 2013 Author Report Share Posted February 27, 2013 Should be far enough away from the seats. I took that into concideration when measuring. So I think this could be a winner. Now I need to figure out how and where to mount my surfboard of an amp Link to comment Share on other sites More sharing options...
