Your right, I found his post on ROE.

im going 4 spl.... i have 2 pa a3000db

We need your under the window line dimensions.

If you want cut sheets and 3d plans, you may need to pay

someone. I hope your good at woodwork, this is not a good

"first project", but hey if it is you'll learn a lot.

These guys will create your plans and cutsheets for $25 bucks.

I could give you dimensions and port size/depth, but you'd have to

figure the rest out on your own.

Yes MOFO12s 4 of them in different boxes talking to a few people I quickly

learned that was not a good idea same with multi maps anyways

I will get the measurements tomorrow only thing I do not understand is

it says for a 12 * Ported box: 2.4 cu..Ft.

I have 4 will I need a box that is * Ported box: 9.6 cu..Ft.?

 

[mcsoul 10+ year member]

yes 9.6 + port displacement and bracing.

It's a fairly easy box to design, your going to

want a lot of port area.

Are you wanting 4 individual enclosures?

Am I reading that right?

if there is no need for individual enclosures then no

most-likely going to power them all by one amp

this way they all move at the same time and at the same wattage.

Ok after playin with the sub box calc to get it tuned right and have the correct

cu..ft of 9.6 I would have to mount 2 firing forward 2 firing up and the port on the

driver side.

Any one see a problem with this setup?

 

[mcsoul 10+ year member]

I think I's try to fire them all up.

What are your max box dimensions?

I'll post you up a compatable spec.
