I need your opinions

Right now I have 2 JBL GTO1002D's running off a Boss 1200M getting ~300 RMS a piece, probably less.

Right now, they're in a triple-chambered sealed box (made out of 1/2" MDF) with about .75 cuFt for the two sub chambers with empty space inbetween. Subs are faced toward the back of the seat (aka toward cab)

I did the math when I was building the box, and I figured it would be about right size (a bit on the small size) for the nominal ported box.

The reason I used 1/2" MDF was because the opening to my trunk is tiny, and it was my first box. I know, "USE 3/4"!!!!!" And I plan to when I get more power.

How the box is now, it's just a simple box with a facade in the front, more or less, to go flush with the back of my chairs.

Picture:

My options:

I was sketching this out a while ago:

Sub down, port back, or just sealed.

(With this build, I'd put through-bolts in the top and then attach it to my rear shelf... but put the nuts inside of the box so that you can't just unscrew it and leave.)

I was also thinking, sub back, with/with out port back, and how the facade is now, except double chamber it so there's a space inbetween the actual outside of the sub box and the amp rack... here's a quick sketch:

(The dimensions aren't perfect, like I said, rough sketch. That amp obviously wouldn't fit there with the seats up, I'd make sure the top offset is enough for the amp to have room to breathe.)

Any ideas?

I'm confused, in that first model, are you talkin about mounting the subs downfiring but box mounted to the rear deck kind of thing? that would be cool imo, make sure you build a wall behind the amps/subs to separate them from the trunk though

Basically, yeah. Subs firing down into the amps. I'm not sure about output firing subs down. I don't think it'll sound good. Any other opinions I. The second design? I'm kinda digging that one.

second one is just meh...boring, I say if your setup is going to be as simple as it is anyway, you might as well do something neat/different with it. And if you put up a wall behind the box/amp rack like I said and seal it from the trunk it shouldn't sound bad at all, and will most likely be louder and sound better than design two, firing back

Well, I guess that's reasnable. If I were to do it, I'd do another amp rack option. The amps are too close to the subs IMO.
