Sealed box for Dual 12" GCONs to fit in my 2011 Charger Hemi

Recommended Posts

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!

Hey, thanks all for the support!

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.

I've been flush mounting for 13 years.

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.

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!

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!

Mounted the amps.

For now, I've decided to not use the 1.6 farad cap.

Nice gear, and nice skills. smile.png

For what it's worth, I've used a few of those kappa models, and loved them.

      Hello! This is my first post here. Crossing my fingers that I'm not breaking any forum rules. I have a 12 inch GCON ordered and the wait is killing me already. I've already purchased an amp and box for this sub and I'd like to have any willing opinions on my choices. 
       
      The amp:
      http://www.sonicelectronix.com/item_43132_Hifonics-GLX1800.1D.html
       
      The enclosure:
      http://www.sonicelectronix.com/item_19279_Belva-Sub-Box-1SV12B-Belva.html
       
       
      A few questions:
      How did I do? Will this pound like crazy?  How much impact will my smaller than suggest enclosure have on the sound? Ported good? How should I wire this beast-sub to this amp? (I'm thinking just running it at 650w @ 4ohms to avoid problems with the following...) Will I need to upgrade my factory wiring in my ride? My battery? My alternator? If I did wire it for 1200w @ 2ohms would this be bad for the sub? (considering I don't roll around pounding at super high volume levels, plus the gain would probably be turned down in this scenario)  It's going to be a long wait for this puppy. I'm fairly certain (hopeful) this will be the best system I've ever owned. A couple a months ago my humble 300w amp and single 12" infinity sub was stolen. My wife gave me a 500 budget to replace it with our tax money.. yea.. $490 spent so far, honey!
       
      Thanks for your feedback and thoughts my fellow bass-lovers.
       
       
      Edit: Oh I forgot one more question! My car currently has a 4 gauge power wired to the trunk. I think if I wire it for 4 ohms I'll be safe right? What would happen if I wired it for 2 ohms?

      Have a 12" GCON in a sealed box. It sounds great but I am wanting more and I know the sub will give it to me if I can put it in the right enclosure. I used the ICON enclosure design for the sealed box it is in now, would the ICON ported design work well for the GCON as well? It falls into the optimal range, 2.5f^3 tuned to 33hz. It is a 2 ohm sub with 500 watts powering it in the trunk of a '96 accord. I have about 32" x 20" x 18" to work with. Anyone have any experience or recommendations for a ported box design that will work well with the GCON?

      I'm still waiting for the GCON 10-D2 to actually arrive, but figured I'd take the time to look for a amp to power this beast now. It will be in a sealed box, in a saturn ion 2003. Looking to present a 1ohm load at amplifier, since I'm assuming that power at 4ohms is asking too much for my budget. No HO alt, or big 3 done yet, assuming it won't be needed yet though.
      I was mostly wondering if I'd need to feed it the full 750w, or if I could get by with less, near the 500w level? Just wondering as my budget is a bit tight currently, and I was hoping to grab the amp for under $150.
      Given what I've listed, would any of these amps work well, or are there others I should be considering? All listed are CEA-2006 compliant, so I'm assuming they all do rated.
      1. Concept CC-D1200 (Apparently 750W @ 1ohm stable, manufacturer refurb, so not new)
      2. Massive Audio N2 (800w @ 1ohm)
      3. PPI BK650.1D (650w @ 1ohm)
      4. Hifonics GLX1000.1D (1000w @ 1ohm)
      5. MB Quart ONX1.1000D (1000w @ 1ohm)
      Thanks for taking the time to look, hoping I get some great feedback!
