    Try to let stuff roll. Nobody will think you are a bitch because you choose not to argue. Do research to find out why or how you maybe wrong. Just because one person says it on the internet does not make it gospel. Wikipedia is full of senseless bullshit for example. Just because it's posted somewhere doesn't make it fact. If someone doesn't like what you do or how you do it, it's up to you to show your character on how you handle it. Try ignoring it. A wise man once said, "It's better to keep your mouth shut and make them believe that you are ignorant, than to open your mouth & remove all doubt." Look it up.

    To keep things simple, if I were you, using the amp & going in an escalade like you said above I would download the specs and design from the store for the dual ported enclosure. You should have more than enough space to make that happen.

    If you were throwing more power on them or limited on space, then you could manipulate the design with modeling another design.

    What's on the store as a zip file for dual ported I believe would be just what you're looking for as far as port area, gross, & net volumes.

    On sub & port placement, subs up and port towards the back seems to work well in most SUV's.

    Also will it change anything by not having a baffle in the middle of the box?  I planned on a shared port in the middle..

    You're actually get a better response out of pairing the subs next to each other rather than isolating them left & right. With the port shared in the middle and nothing splitting the port you will create unwanted turbulence in the port. Keeping it simple the air from both sides crash into each other and creates pressure as the two forces blend and create air friction when competing to exit out of one opening. Keeping the subs paired close to each other in a common shared chamber almost makes the two act as one. Audibly the change may seem minimal, but you did mention sound quality. Quick visual reference look at altoncustomtech profile pic.

    Anyone ever bet on sports? Thought it may be a fun extra spice on the NFL since I watch it a lot anyway.

    I could make a buttload of money if I bet against myself...lol 

    I don't bet, it'd be more profitable if I just tossed the money out the window.

    It's been my experiences that it's okay to go larger than recommendations per sub as long as you really watch the port velocity. Modeling kinda gave me an idea as to what was way to low on velocity. With those subs you could even set your limits on preferred velocity a little high from and audible stand point. With that much output the chuffing with be very hard to hear.

    With that in mind, the reason I would set the bar higher is that when going with a larger than recommend enclosure there's a point where you won't have enough velocity to keep the right amount of back pressure inside the enclosure causing the sub to be more prone to bottom out on the lows such at anything around 32hz & lower.

    One thought, and I am just tossing this out there is that you could just design a single enclosure for each of the subs. Stacking the 3 side by side and the front baffle would still give the illusion of a common chamber but the internals & port would be so reinforced on the inside it would diminish any flex from having such a large port.

    Designing a single enclosure for a single sub would be a lot easier to control your design. If you ever had any failure from one sub it would keep the others from shreading themselves apart as well being that there are an odd number of subs in the design.

    As far as a velocity cut off on the min, I really can't say. I use a different program when I model & design. But on mine I would try to not go lower than maybe a 6% mach. Without modeling this myself it may even go higher. Increasing the area would lower the percentage bit also makes the port longer, but you already are aware of that. In my opinion a 36" long straight port really isn't that bad. I've built & seen some that were well over 50" and without sacrificing anything other than space. If you got it use it...lol

    Tuning lower can flatten things out on the response curve but generally I don't like going lower that 26hz to achieve that. The actual gain in the cabin on tuning would have to be answered by the meter. I know in my little ranger on just a blow through, if I tuned the enclosure @ 26hz. my peak would be at 32hz. which for me was awesome because I listen to a mix of rock & rap. With a flat response curve I could play a variety of songs during demo and still turn a lot of heads.

    You asked for opinions.....we gave our opinions....you obviously didn't give any rats ass as to how to interpret any of it. I have a lot of experience myself, but we aren't having a who can piss further contest. Most of your responses to anything did give everyone only one perception, you really want to build some sort of a bandpass. Never did I ever see you put forth as much effort toying with a ported enclosure nearly as much as bandpass. Asking for opinions with a closed mind is kinda arrogant.

     They understand what the other people have done to get their rides to the show week in and week out. They have respect for that effort....people online not so much

    It's hard sometimes to type what you're trying to say & not have people read it and misunderstand you sometimes. Face to face you can read body language. But on a website there are a lot of ignorant jackasses that love to do nothing but start things by feeling the need to argue & bully people. Speaking only for myself, if I type something or say something that upsets or offends someone I appologize. Unless they need to have something said that makes them upset. I would rather have everyone laughing at something I said on purpose that was stupid than have them think that I am serious and stupid. I know I've been corrected many times and got bent out of shape until I realized I was wrong.

    Remember everything you have ever "heard" is from someone with some driver in some vehicle.  Your situation is not the same.  sq in per cuft is not a way to determine port size.  I realize you are trying to move air, but again you used the word musical in your needed description.  If you care at all about the latter don't go but rules of thumb or the grapevine.

    I agree, the bandwith on the ported enclosure is more efficient for music. Both bandpass designs modeled have a nasty roll off. Will they be loud, yes. But if you care about moving air & being pleasant to the ear while playing music then you will need that line to be as flat as possible without tuning ridiculously low. A wider wave tends to move more air as far as frequency goes. When playing music, songs are never produced with a similar frequency range on the bass line. That's why one song will hit like crazy in one design & lack output on another design. Unless you're going strictly for SPL, I would stay far away from a 4th order design. There are never any "rules of thumb" when it comes to any design beign that there are too many variables between not only the equipment but the variables in the actual vehicle itself.

    whats difference between velocity and meters/second

    Velocity is the rate of speed & distance an object travels. Meters/second is a measurement of selected distance during a selected rate.

    i.e. feet per second, miles per hour....ect.

    Nice enclosure.  Your not very far away from me at all.  Milford ohio is where I'm at. 

    Yep, I've spent the past year doing the sheet metal hvac out at Mercy Anderson Hospital expansion too. But where I live is just outside of Harrison.
