Default ZV4 4th order Blowthrough Help

Alright guys I'm needing some help with a enclosure. Im wanting to do a 4th order blow through box for a single cab silverado. I have 2 ZV4 15" subs with SPL cones. Im strapping two sound stream ta1.3000d amps at .25 ohm lol with box rise i think i should be ok. Working with this until i can save for better amps. Anyways my dimensions are W: 49.75" H: 19" D: Trying to stay around 36"
I was told by multiple people to do a 3:1 ratio box so 4 ft3 sealed and 12ft3 ported. But after displacement and 1.5 thickness all the way around to keep my box stiff as hell its damn near taking up my whole bed which i just don't want to do right now. Im open to all ideas from my basshead community. Im also willing to throw some money to someone for a nice design must have good references in that case. Thanks and god bless

Why not cut a larger opening and do regular ported

It will take up less room

Well that's true but I'm already iffy about cutting a hole just big enough for port lol also I want more range in bass. I listen to all sorts of music and ported boxes that I've used just don't seem to give me the range I'm looking for hopefully I'm explaining myself correctly thanks again

What ohm are your subs? Dual 1's I'm guessing? Are you strapping at .25 nominal load or .5 with each amp at .25? Either way thats way too low for those amps I believe. I would run them seriesl/parrallel. Wire them both to 2ohm and then series them together for a 1ohm nominal load...each amp at .5....only amps I know that can take .25 loads are sundown or a comparable korean made amps.

The amp is stable at .5 ohm. They are dual 2s. Each amp will be at .25 but I'm pretty sure it will be more than that. My multimeter shows subs sitting at 2.3 ohms

Personally i would run them strapped @2ohms rather than .25.....i trully dont belive those amps could handle a .25 load.....a 0.5 yes...thats what they are rated for...but they rate those amps at thier threshold...not half of thier threshold...do what you want but just a word of advice...

They would see about .35 as sitting right now in a enclosure I can almost guarantee they will see .5 and probably a lot more . I just want to get as much power as I can out of them

Just keep an eye on them, if they go into protect mode then you'll know why...
