Freshman6969 Posted April 11, 2010 Report Share Posted April 11, 2010 alright so i finnaly decided to get rid of my prefab since i hate the port just looks dumb , anyways if anyone could draw up some box plans for me id appricate it, i cant really seem to find any dimentions for my "trunk" but eh dont think a box is gunna be 3 feet tall >.>, width wise ill mesure tom. heres the specs of the subs, mind you theres 2 Fs (Hz) 38 Vas (cu ft) 4.017 Sensitivity 87.2dB Mounting Hole Diameter (Inches) 10.91 Mounting Depth (Inches) 5.51 my gpa will be building it from 3/4 MDF if we can find some laying around that is, we owned a millwork for awile, but would say 1/2" MDF be ok? or just straight say....pine or oak? jw Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k!

Guest Posted April 11, 2010 Report Share Posted April 11, 2010 dont do 1/2. 3/4 with wood dowel bracing will be fine. says right here on crutchfield, ported box volume: 1.5 cubic ft. so do a 3cuft box (after sub and port and bracing displacements) tuned to probably 34-35hz will be fine.

Freshman6969 Posted April 11, 2010 Author Report Share Posted April 11, 2010 (edited) my gpas old, so he wants pure mesurements, cubic feet mean nothing to him lol, hes nearly 8 0 but hes a tough fucker Edited April 11, 2010 by Freshman6969 Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k!

Guest Posted April 11, 2010 Report Share Posted April 11, 2010 (edited) you can figure that out yourself since i have absolutely no idea what your max specs are. plus its good that you learn now instead of later. find Torres (thats his username) calculator on here and play with settings.

P4killer_ Posted April 11, 2010 Report Share Posted April 11, 2010 and really you dont have to worry about bracing its just 2 12's and i think those cobalts are the low end like 500w or something iirc, just a simple 2 12 box will do. Use the RE calculator, itll do everything for you even a cut sheet i think. just google RE box calculator or something Quote Setup: 2010 Hyundai Elantra Factory Unit via 4 chan NVX LOC Excessive Amperage "H/O" Alt Xs D3400/ Xs XP3000 Big 3. 2 Runs of +, 2 Runs of - DD M3b and 2 12" AQ HDC4s Link to comment Share on other sites More sharing options...
Freshman6969 Posted April 11, 2010 Author Report Share Posted April 11, 2010 yeah i dident think it needed bracing either, there 400watts about, but i just dont know where to start from Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k!

Freshman6969 Posted April 13, 2010 Author Report Share Posted April 13, 2010 daily bump, looking for someone who can draw it out with mesurements, port can be changed around if need be, but im trying to stick with that design Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k!
