bumpin04voy Posted March 20, 2008 Report Share Posted March 20, 2008 (edited) well pretty much the title explains it. i built a box for my 2 18in BTLs ...subs up, port along the bottom facing to the rear of my truck. its 11cu ft at 34hz.... i dont know what i might have did wrong but im not happy with it...sound wise and on the meter..(146.6 on the TL) so im comin to you guys to help a brother out. my dimensions are 44wide, 24 height, doesnt really matter how deep.. i want to do swappable ports to so i can burp them at local comps. maybe its just me being used to 12s or its my box but i hate not having bass on every song...just seems like it only picks up the real low notes and nothin higher Edited March 21, 2008 by bumpin04voy Quote Avic N1 rockford 400.4 type-r comps all around (2) 18" Fi BTLs fully loaded 11 cu ft. vented box 34hz (2)RD Audio 1750.1 (4) optimas Link to comment Share on other sites More sharing options...
