Posted July 14, 201213 yr I just ordered a pair of GCON 12" D4 to be powered by a couple of 800W RMS amps. While waiting, I figured I'd build a box to fit in my trunk.After deciding I wanted to go with a sealed box to save room on space and measuring the insides of my trunk, I sat down with google sketchup and this is what I came up with.It will be cut from a sheet of 48"x96"x3/4" MDF, wood glued, and then wrapped in trunk-matching carpet.Let me know what you think!
July 14, 201213 yr Author Hey, thanks all for the support!Looks great! Not your first time using sketchup eh?Heh, actually, I picked up sketchup just for this. It took me a few hours and a few attempts, but I think I got it down. It makes modeling pretty easy.
July 14, 201213 yr Admin Great work on the box, air space looks right. Which amps are planning to use?
July 14, 201213 yr Author Great work on the box, air space looks right. Which amps are planning to use?Great, thanks!I have a pair of Infinity Kappa One amps 800RMS @ 2 ohms each.I have an oscilloscope to test the actual power output (and adjust crossovers, etc), and on a high-impedance load, i was actually able to get around 40Vpp before the amps start clipping (on a 100hz sine wave). Now, with a 2 ohm load, I'm sure the thermal shutdown circuits will kick in before hitting this voltage, but hopefully I'll still get around 700-750 watts on a 2 ohm load.I've got a 1.6 farad cap (yeah, yeah, i know), and am running 0/1 awg wires from the battery to the distribution, and then 2 awg to the amps.

July 16, 201213 yr Author damn nice bro!!Now where's my lay out you said you would hook me up! Thanks!Your design is done, meet me in the chat Edited July 16, 201213 yr by joemosfet
July 16, 201213 yr Author Finished building the box for now - all assembled and glued. I might add dowels or screws later.Here are the build pics:Here's the circle jig I made for my router to cut the holes:I then rounded the inner edge of the outer board for aesthetics.And then painted the areas black in case any cuts in the carpet show through.Perfect fit!
July 25, 201213 yr Author Carpeted the box today!Ready with some glue:Mask up the holes so we don't get a bunch of spray adhesive inside.The first seam:A more complicated side seam:And all done up:Do the same for the otherside, and prep the speaker hole:Apply some glue and press it all down:Repeat for the other side, and all done!
August 16, 201213 yr Author Wooo, UPS claims a 50 LB package will be delivered tomorrow. Now I'm excited.
August 16, 201213 yr Nice gear, and nice skills. For what it's worth, I've used a few of those kappa models, and loved them. Edited August 16, 201213 yr by stefanhinote
