Next build, looking for feedback

[ghostismyname]

So im looking to do a rebuild for my two 18"s, and I am looking into a 4th order. I finished a gsketch and got some dimensions, can anyone let me know if im going in the right direction here? Side note more bracing to be done. And subs inverted with motors in ported section.

Dimensions are as follows,

Sealed Section H=34.5 W=41 D=11 6.60 ft^

Ported Section H=34.5 W=41 D=21 13.68 ft^ (with port)

Port H=14 W=14 L=6 196 in. of port

Anyone?

Just need to know a couple things, like is my tuning high enough? Is this a good design? Any suggestions?

What 18's do you have

How much power you throwing at them

And what do you want them do?

aq hdc4's 4400 watts, (more later, around 8000, but it doesnt have to be on this build.)

I'm mostly concerned about my tuning and if its high enough

in general what i have seen other people do when building 4ths that they have had good success with is to make that front port removable or tunable so that you can adjust it once its in your car to see how it interacts with your cars acoustics etc. Since this is your first 4th and done know exactly what to expect that is what I would suggest you do. It is what i would do for sure if i were in your position. Good luck!

in other words: start with more port area and higher tuning than you think you will want and then shrink it down to lower tuning until it plays like you want

Alright thank you
