Dimensions:
39.5" wide
19" tall
18" deep.

Josh can figure out something good!

oooh. I'm on it.


Is there anything particular I should aim for as far as response goes? Also, If I max out any of those dimensions, is the box going to hit into anything? I'll probably shoot you like 2-3 designs.

I don't think it will. My horn for the 2 12's fit great. It was 36x22x14 or something like that. Also gave him my 4th order that was 38x16x16.

Just something that will take care of business, really. You know how we do.

Here we go. I'm still playing with other designs, but they take longer.

I used the T/S for the AQ SD2.5 to model response, because of the similar response.

That port is small, huh? Nice tho... response should be tight(in a PT)

So far, It is the loudest per watt design I have too, and the cone displacement looks to be lower then a bass reflex in the same footprint.

I'm going to call it a night. Keep me updated on this guy.

Will do! Have to remember that he's going to be running them on a Big Bang 2400.

What was cool too, was I normally start with an excel based calculator for T-lines where I stick in all the driver parameters, and it spits out some enclosure parameters. I then take that basic design and stick it into hornresp where I typically tweak the parameters into something I like.

For this, The basic parameters given by the excel calculator were dead on with the response curve being aimed for. I whipped this one up at warp 9 and it worked out.

Makes me wish I had 38" width for a box in my car sad1

I think it will be ok as long as attention is payed to what the woofers are doing, and as long as the amps don't run a train on them with a square waveform. I'd keep the amps dialed back a little, and the subsonic filter at 30hz.

Depends on the enclosure you go with, but I think it will sound better and be louder facing the rear, unless the enclosure becomes too restricted by the rear hatch.

I know my hatch only seems to like woofer/vent back.

I'd say play around with it a little, with box placement... you never know, you could find that "sweet spot" just by moving the enclosure around in your vehicle.

But like what vmann said, facing back to the rear of the vehicle... that seems to always work with most applications.

Let us know what happens bro!

I have tried a few different set ups. I have fired subs and vent up, front, and back and by far it seems to be better subs and vent up. I would like to try subs up vent on passenger, and subs up and vent to the back, but I don't really want to build a box just to try those orientations.

Vmann I really miss having my civic hatch, I had one back in the day and ran 16 JL 12s, off of a usamps VLX-200, and a usamps HC-50 on my interior. It kept me in a 0-250 power class which was alot of fun. I am thinking the reason the pt dosent like the subs and vent back is because the hatch has an odd slope, and I think it causes some funky loading.

I just picked up an mechman ho alt for it, I have all of my equiptment but now I am kinda thinking I might want to go another direction on my substage. But it will have to wait for me to get back from Brazil. I am going on vacation for three weeks. But it would be nice to have some help from anyone that has some free time.


I have knowm Cam for quite a long time, he knows me pretty well so if anyone want's to help I would appreciate it.
