Serious Help with an enclosure

[scooter99]

Ok everyone here's what I'm looking at. My head is going to explode I swear to god! I'm doing an SQ type install on my Honda Civic Sedan. My build thread is in my signature. I've only ever built sealed enclosures my entire life of building, and I'm trying to venture into a different realm of sound with vented and other enclosures.

I recently found an enclosure that I love the looks of, and would love to do in my car. I was going to try and do two subs with that look, but I don't think it's going to work, but I also have nothing to base that off of. I have a pass through in the rear seat that measures 11" high by 5.5" wide. I was originally going to do just a standard vented box, build it with the matching cutout in it, so the sound could travel through it better, but the more I deal with this the less I like it. But it's there, and if I could vent through it I'd love it, but I"m no longer set on it. My issue is, I want to make sure the sound can travel through the rear seat efficiently. I've also got a 3" deep by the width of the seat wide component panel behind the seat that the sound is going to have to fight through. Also another reason for the pass through. I have alot of components and I wanted somewhere to keep them all neat and tidy. So that kind of needs to stay. Here's the component wall:

From the back seat

From the trunk

In the rear deck, I have a 4" by 32" sliding drawer amp rack going in. I'm able to work around it a little bit, but obviously if a vent will go through the top into the cabin via the rear deck, I have to figure out how to do it and retain the drawer. Maybe a single vent in the middle and then split the drawer into two drawers would be ok. Anyway, moving on.

Here's the picture of the design I love:

This was with a JL woofer, and my subs are Hertz High Energy HX300D's (dual 4ohm). I have two of them, and have two Audison LRx 1.1k mono amps on hand that I was going to run with them. However, at this point, I'm not tied to using both. If I can great, if not, I'm not going to loose sleep over it. Here is the specs and manual for the HX300D's.

This is what I made, from my idea, on MS Paint on what I was thinking. But I'm not sure there's enough room as I said before.

And it doesn't have to be that way I guess. I was hoping to show off the whole sub but if it was front facing, meaning toward the cabin so the magnet was toward the trunk, that would be cool too. The magnet is chrome on the bottom so that would look nice.

So I think that's all the info I can think of. The space that I have to work with is 40" wide max x 14.5" tall max x 11" wide top and 17" wide max bottom (wedge for up against the back seat).

Can someone please help me out on how to do this? Design a box for me, or something? I'll be happy to throw a donation to someone for their time. I know people can't charge for boxes anymore on here, but I think everyone's time is worth something. I can build, I follow plans well, I just have a problem with lack of knowledge on the design. Thanks ahead of time for any help.

if u want to do a 4th order like that have a sub on each side (firing toward each other) with a common ported chamber in the middle & port thru the armrest.

sealed - ported - sealed.

& the whole back of the box could be plexi to see the subs...

[scooter99]

That would work. How would I figure out the sizes?

Scooter I learn alot from you man. You are the shit. Hope I haven't made you mad with the billion questions on my build. Thanks for all you help me with. I won't disappoint you with my build! I promise

[scooter99]

Thanks man. No worries, I'm not mad at all. Just busy. Just cause I'm on doesn't necessarily mean, I'm on. I won't be disappointed, you've already impressed me. I don't want you to be disappointed.
