Uhh that's not a 4th order. That's a ported wall. But the subs will be fine behind the seats.
here is one more idea for keeping the port above the seat. i cannot keep the subs tottaly behind the seats there is a small portion of the subs on the top that will be sticking past the line of the seats. the seat are 25" from the ground. heres the pictures.

Haha yeah I know that was one design idea I had for having the port above the seats just wasn't sure if have the subs close to the seat firing at them was a good idea.

Keep the port unobstructed. I'm actually going to hack off the headrests of my front seats because they block my port a little.
yeah i already took my back headrests off. so if i dont wanna abstruct the port would the same go for the subs as well. if i had the port above the seats i would have to do the sub behind the seat firing at it. If i made sure that the subs would not hit the seats or rub against them would that be okay.
if i did this deisgn i would have to keep the the angled sides, which i dont mind because it would make the depth less giving me more extra room in the back.

I would just build I good box the sundowns. And I think I seen you say you stuffed the box with polyfill stuffing to take away some of the space. Adding the polyfill with actually make the subs think they are in a bigger box

not sure if this has always been said but i think making a new box would give you the best possible results.

E-series arn't suited for 4th orders? obviously whoever says that has no CLUE what they are talking about...
#1: The t/s parameters say otherwise
#2: I have heard several set ups in person using them in a 4th, and they sound awesome.
i hear apposing statments from everyone. I just have the ask and see if more say yes than no. seems like forums are hit and miss for fining the right answer. basically how some people will say a box design is horrible and wont work but them you have some saying its the best.

The 4th would be best for putting the port above the seats. But loading may get weird for the woofers. Can't say for sure.
If you laid the woofers down horizontally. They would load a lot better. Because if you kept the woofers how they are now but had the port at the top, then the top two woofers would load into the port and the bottom two wouldn't.
yeah thats a good point. Is there a problem with the port being there? should the port having something "CLOSE" to fire at? with the windshield being the first thing that the port will fire at which is prob about 4ft away from the port. Idk if that is an issue with a 4th or not.
if i had the port under the seat line firing at the seat would that be better or would i give me some better results? I know sound waves need to bouch off of something and have heard the sooner they bounce off a surface the better.

I can't fix my font after copy/pasting that so fuck it.
What makes a driver suitable for a 4th order or not is it's EBP.
EBP = 1/Qes * Fs
Now that you have you EBP, you know what your speaker is suitable for!
If the EBP is 100 or more, it’s best for ported boxes. (And 6th order bandpass)
If the EBP is 50 or less, it’s best for sealed boxes. (And 4th order bandpass)
If the EBP is between 50 & 100, it will work in either style boxes. (And either style bandpass)
EBP is 51.57.
Will work fine for a 4th.
And you should tune that a little higher. The tuning point for 4th orders differs from typical vented boxes. The tuning point is actually the low-pass point. It will be attenuating frequencies above tuning.
I say tune it around 45hz.
Which box do you think I would have better output from. I've decided I wanna go with a port above my seats so I don't have to have them folded down all the time. This is the best picture I could get of my second row seat. I would like to have the port above the seats. Would that be a good idea or would that all depend on the box type
-
I wanted to look up their T/S specs to check if they will work in a 4th but sundows page won't work right.
yeah its down for me too. just goes back to the main page. what is it that make a sub a "good" sub for a 4th order.
-
Please do it. Great idea. Somewhat "budget" wall. Great potential to actually slam.
Sorry I couldn't offer any knowledge, just encouragement
Well thanks man.
Hopefully some knowledgable will reply. Soon.

okay so ive been working on a few designs i wanna do a wall behind my second row seats so a "C" pillar walls. I know 4th orders have more more potential to get louder as far as spl goes. I've seen a few people run the e series subs in 4th orders but some say they are no suited for a 4th order.
Would a 4th order work for the e series
info-
subs: 4 sundown e15's
vehicle: 2004 toyota sequoia
location in vehicle : behind second row, c pilar
box type: walled 4th order or ported wall
amp: ta1.3000d
This is a design concept.

Moar updates now . Please. Build looks sick.

ive been looking for a bench test on this since i see amp test tuesday

Heres the thing. It cant be a one time thing unless you are going to put it on as part of the show. If thats the case. Give someone 60 seconds to bust the windshield. If they do it they claim the prize. If they dont no prize. This gives you guys the chance to inspect first. Make sure nothing is hokey with the glass previously or someone hasnt removed something to make it go etc. That will draw a big ass crowd.
Whatever is done has to be done and validated. While the lowest voltage is cool its hard to validate. Plus people will just pull a battery or two and say oh look.
Heres the best one. Let's call it the I have a dream award. That one person who doesn't quite have the money but they are trying like hell to make it work. They may not have the best gear but the install is clean. They've got nice work done and take care of their car even if it has a million miles on it. They take pride in it even though its not the best car on the planet and their work and stereo shows. Thats the person who I feel would benefit the most from a cash prize. What would be even better if you could get others to pitch in on it. The sundowns the DCs the other vendors and get that person a full install that they may not ever have a chance to accumulate with their current financial status.
this is one of my favorite ideas here, xs should take like 10 ideas and make a poll out of it/
deadening top of box?

i defiantly agree with you on this one. i have never seen the real benefit based on exactly why your saying. I guess i could see some benefit if there was a way to loosely attach them without have them so loose it would bounce But properly bracing the box will stop a lot of that in the first place
