[gibblegeibel]

i have 2 12 rockford fosgate p3 the versions that do 500 watts rms and was looking to build a ported box for them what do you guys suggest for size and hz.

my max demesions are

14 high

36 wide

16 deep

What power are you running them at and what kind of tuning would you want?

[skittlesRgood]

are those dimensions until you hit a wall or is one of those dimensions open?

[gibblegeibel]

i have till i hit a piece of the car. and i would like to tune about 40 hz

Ok, I made it the max dimensions it could be, so you better test fit with a cardboard cut out to make sure it will fit properly.

The box is a bit underrated but should work.

Also, I am no expert just to let you know. If someone else wants to chime in and give some suggestions, I would love that.

Too much port per foot^^try 14 port per foot

two things here. one, that box is fucking tiny. yeah the port should be smaller and that will help BUUUUUUTTTT, he said those measurements were until he hits a wall. so just the subs being on the front of that box means that it wont fit. it goes over the max dimension. but even if they did fit, you're firing a sub and port directly into a wall. there needs to be AT LEAST 4" between the port and a wall.

so to summarize... you don't have enough space for two 12"s ported, and you should never take box building designs from a noob. either go with a sealed box or sell one of the 12"s.

ok

[gibblegeibel]

well the box will be in the trunk of a 2004 nissan sentra 1.8s

Well, I know the 4" rule, but it's also way easier to design a box if you had all the adequate information or could see everything in person. I personally wouldn't have 2 12" woofers for that small of an space. Takes a lot of planing to get a system to work together smoothly. I would listen to Skittles and take a different approach for your system, make it well planned.
