Sub/Port firing option? which would be louder?

It's all completely car dependent.

Unless you know someone with the same vehicle and has tried multiple locations, we can't tell you for sure.

Unless you have a good bit of space between the back of the enclosure and the back of the vehicle I can see you not being happy with it.

Yes i know.. but in general thinking about a single cab. With my current box, it loads off of the roof which is pretty far away. And it may be harder to compress the air in my cabin because it can easily flow out of my windows. I've heard that utilizing the reflection of sound waves in your vehice (loading) helps with something or other? Not sure if its SQ or SPL. Any thoughts?

The vertical part of the box above the sub will be against the back wall. Should I just down fire?

Try the downfire method or you could try side venting into the cab corners.

My original plan was sub up, external port into the passenger side corner so I could switch tuning easily. But I think I'm going to put a battery there. Now I'm leaning toward the idea of porting out of the front with the flares (like in the picture).

I'm thinking about firing the sub like the drawing, but maybe decrease the angle so its closer to a downfire setup. But i'll still have an angle on it so the sub will be able to breathe and it may create a horn type affect with the angle.

Give it a shot, you will have some major up front bass with that setup.

Up front as in by the windshield? kick? my head? lol

I'd like to give it a shot, but I'm trying to do as much planning as I can since 3/4 MDF is 30 bucks a freaking sheet!

I remember when I started building (about 4 years ago) 3/4 was like $22.. now the 1/2 is $22..

No kidding! I'm paying $32 + tax per 3/4" 4x8 sheet!

Good question, look at firing the port towards the back along the rear wall.

Price of fuel has gone up, lumber is very heavy thus expensive to ship.

[Kanaworm$ 292]

Price of 3/4" MDF is $31.99 here. Was in the low $20's just last year on sale.

Load off the back wall.

[imhungnurnot 9]

Load off the back wall.

Sub? port? sub and port?

[Kanaworm$ 292]

Port off the back wall. Sub up front downfiring at the angle you described.

[imhungnurnot 9]

What if i fire it into the rear wall?

Sorry.. by the time i replied you already answered..

i would go with sub forward port up, you may have issues with the loading off the back wall, depends on how much space would be between the sub and back wall, i'd say you would be safe if its greater than 6" with sufficient room for airflow from behind the seats to the front (or under)

[jlftn 11]

not to mention the geometry of the box would hurt airflow within it, start from the sub and ask yourself where would the air compress, basically back into that far left corner, then to exit the port it would have to pass by the sub which is continually compressing/decompressing the surrounding air (this is a very watered down version of what really happens) but you get the idea

wow you guys have it cheap for 3/4 mdf i payed 48.95$ a sheet for my box 4X8

[BanginGMC 23]

Load off the back wall.

Sub? port? sub and port?

If you can get a nice amount of space between the back wall and the port, so its not loading off with 3 inches of space between.. understand?

Also, sub facing H/U could be interesting with the port loading off back wall.

This is a small box, so trial error would be easy to do.

You should check sq_mgb's build log. He also has a regular cab truck with a console box. Here's the link.
