sub box size/tuning help

[Mudcrab92]

Want to build a sub box for 2 alpine type r etc etc.

Can anyone give me some dimensions for a box that will fit into a vx holden. And that is slot ported to 35hz and is 4.5cubic foot.
Subs facing towards roof of boot and slot port also facing the rear would be good.
Ive failed with the whole box calculator im just not smart enough to understand a few points haha.

Thank you.

my best advice pay someone

Is that because you are a mobile electrician?

Talk to some of the other VX owners on here man

Also, try Nic92, he knows his car audio

From what I've learnt you can't use a l shape for duals. But I don't know much at all, however there are lots of calculators online which I have found.

Na im not paying anyone. My old box I paid for but I wamma have a go at building one myself and get my head around it while I build it piece by piece.

Although I dont think many vx owners would have such a bih box as it literally takes over the whole boot hahshs

Use the rockford fosgate box calculator and then use a port tuneing website or program.

Try this man, might be handy:
Rockford Fosgate® - Woofer BoxWizard

that Rockford wizard would be good, but im not 100% of the dimensions of the box id need for it to be 4.5cf.

This is where I stop haha. I dont even know what the cf part is

As you may have noticed, I have limited knowledge in car audio

Put in dimensions then convert litres to cubic feet in google.

L shape ports are pretty common, so you could use this for tuneing etc. But it is in inches.
