Box build

[Tallyfiman]

Hey im getting ready to build a box for 2 fi ssd 18s in a 96 jeep grand cherokee and was wonderin if anybody could help me out or tell me a good software i could get to design a good box

Give dimensions please, but I'm not sure you have enough room for 2 18s, especially those 18s because they like quite a bit of space. Minimum of 12 cubes, but doing minimums isn't the best way to get the shattering lows most people would expect from a couple of 18s. More like 8 cubes per sub, so that is 16. Add in port, bracing, and sub dissident, that's another 2-3 cubes.

alright im about to go measure the back and thats what im lookin for is them loud lows

[Tallyfiman]

from the back seat to the back latch is 35in about 40 in wide and 33 in tall but i wouldnt mind lettin the back seats down to give it and extra space it needs

[CleanSierra]

Ok, I'll check for you what can be done. It's the 35" basically from the seat to the hatch exactly?fI'd have to dial back to allow the port to breathe.

[Tallyfiman]

yea i kenw it was gunna be complicated because i have a box for 1 18 fi in the back and it pretty much took up most of it

[Tallyfiman]

but like i said i wouldnt mind putting down the back seat if that would be an easier design and sound better

Here is my version, still you would need 4 1/2" of free airspace in front of the port, you should state your amp power, this will work at least about 20% above rated power without issues:

i have a 2100 hifonics brutus amp
