Building a box for two Digital Designs 9518i sc

[AZaudio]

Height 29" you should be too near the roof, subs up / port back is not going to work well, consider a wall.

Why would it not work well?

I could add more depth to work with if need be to accommodate

Maybe you could go all the way to the back and do subs / port up (across the back) and lower the height of the box but neither this configuration has been very successful to many of those who tried in any case you would need to deaden the roof, that is a very decent deadening job, if it was me I would probably still do a wall.

My skills are not wall ready yet

Deadening wont be an issue for me, especially materials

Edit: I could get rid of the plastic cover on the hatch to add another couple of inches

[Joe X]

Yes walls are a lot of work no doubt, here is the alternative to subs up / port back I was talking about:

With the space gained you could lower the height of the box, still you would need, as said to deaden firmly the roof.

I would much rather do this design than a wall for now.

How could I come up with dimensions for the box above?

[AZaudio]

I believe this will work but I don't know what to do about port dimensions

How can you wire two 4 Ohms subs to 2 Ohms ?

Two DVC 4 OHms subs ::::>1 or 4 Ohms on the amplifier. That's what I think.

For the box : double layer is a good idea, but you can use a lot of bracing instead : you may gain weight, and have a stronger box.

I am sorry, you are right, I meant wire to 2ohm per sub.

So looks like I will be using rods and a double baffle, thanks

2ohm per sub to a mono amp still will equal 1ohm. It's a mono amp not a 2channel

I get what you're saying. I worded it incorrectly twice. I completely understand that I will be going from a 4ohm load to a 1ohm load

Building begins today, any input appreciated
