I have a 95 S10 truck extended cab with two 12's and it won't do nothing with both windows down, I have to have one up all the time and that's in a custom enclosure from D4S that's built just for those subs... I thought it was the shape of the cab that was messing with it but idk I think if it's more square it will be better then rounded like your jeep is more square inside where my truck is all rounded in the corners I feel like it has to much flow inside the cab
I had a 2001 S10 and it was the same Deal. Had a 10" tuned to 31hz, and it would hit really hard at 33hz (strong cabin resonant frequency) and then drop off a fuckin cliff just a few hz below that. Seriously it had ZERO lows below 30hz lol. No matter how hard I pushed it. One window down made 33hz a lot louder, and both windows down made the 40-55hz range a bit louder.
Love all the videos was wondering when it comes to port size and box size do I over build the box to compensate for port? Say like I want the box 12 cubes after displacement of subs and port do I then add what displacement would be and build it to say 16 cubes but ends up 12 cubes after displacement of everything? Thanks again
The port does not account for any of the room of the box so say if u need 5 cubes for a sub u would need a 5 cube box then figure out your port and add that much to the box, like zero or the port length adds to your desired box size so the port will be an addition to the box
In another video I heard him say 13sqin per cuft and also said fire it at rear driver panel so will be louder for passenger side, I’m gonna build a box for 2 15s subs up port firing at passengers side panel so it will be louder for me haha and I’ll follow his 13 sq in per cuft recommendation as that makes designing port way easier good luck with your build bro ✌️ Jerry is the shit I’ve learned so much watching his videos dudes fkn awesome posting all this first hand knowledge deserves that Emmy he wants 🏆
@@soundofbass6842 in a sixth and a fourth at least with b pillar walls there always has to be a front port unless it is something that is extremely unorthodox, the sixth he has, has a port front and rear both tuned differently usually one octave off from each other I think his is tuned a little broader then that but usually sixth r turned like 26-46 or 22-42 something around that range
@@soundofbass6842 God no I don't want to either but I build some, I built my b pillar wall and about to rebuild it again to go bigger with more subs 6-18's to be exact, there are a lot of talented designers out there that are much more qualified than I would ever be, I can design standard ported boxes like most people and maybe small fourth orders but I don't understand the kind of magic that is done with the ports that don't abide by the same rules that I am use to, and I don't understand how to figure them I wish I could tho
Dang bro you keep cranking em out! *So your telling me that a sub in a sealed box in a room with the door open is all a 6th order is or am I missing something? * sub in a ported box in a room I think I meant to say.
It's really refreshing to have someone cut the bs and tell the truth,thanks,appreciate you.
Do you think you could give an explanation of how to use the ts parameters of a sub to figure out how much port area per cu.ft?
there's a rule of thumb to have a quarter of your cone area for port area
@@brycedupps8719 a quarter‽ I've always gone with 40-50% and it's worked great. I build custom boxes and a quarter is definitely not enough.
@@bailey2517 especially for something like a sundown x or a woofer with lots of xmax will need more port area
@@GTILOUD exactly
Jerry what size aero port would you put with 2 Avatar stu 15s in a just over 7 cube box?
You the man Jerry!!!! 👏👏👏👏

Great info on this one Jerry 🤘🏼
Does it matter what size subs your using or do you always use that 15-18 rule
Motor strength xmax and power you're putting on them factor in.
I never really thought too much about tuning a 4th to gain that much,I may try it one time.
Thx Jerry.

Yes that's about right, there's programs like sub box pro that will calculate it for u
The port does not account for any of the room of the box so say if u need 5 cubes for a sub u would need a 5 cube box then figure out your port and add that much to the box, like zero or the port length adds to your desired box size so the port will be an addition to the box
What is your recommendation for port area for good hair tricks?

Doesn’t a front port also load the subs? I dont get why someone wouldn't make one
Idk if u mean this exactly but his front of his box is a port, usually the mouth of the box is the secondary port in the sixth order
@@1-Six-dee He mentioned people not doing front ports, I was so confused

A woofer in a sealed box, in a car with the door open works like a series tuned 4th order so yes! a 4th not a 6th.
What size are the pride subs
15" TV3 series
Awesome thanks...I did hear you say 300 each right
Can't hear it I even went to another video an it how sound but this one dont
its got sound for me
@@2015GTPP it did for me after I reloaded it a few times. I live in KY and it will show I have good service but really don't
