Mason Poston Posted April 15, 2015 Report Share Posted April 15, 2015 I have 2 RF P3D2-15 in a 2004 avalanche midgate that are currently on a free air setup with my bed acting as a huge box. I have tried using a program to design my ported box but it failed miserably and sounded terrible so i threw it out. Now I need professional help, I already have around a 4" wide (may be wider not 100% sure ) 16" tall square hole cut for the port from the old box that i could use but I need the depth, width, port length, etc.. does anyone have a diagram they could give me or some tips? And the perfect height was also 18" so if that could also be a set factor that'd be great. Would like it tuned to the low 30s. Any help is appreciated thanks!

Joe X Posted April 15, 2015 Report Share Posted April 15, 2015 It would be best if you took detailed measurements and post pics of the working area and the hole you say you made, also what amp you are using. Link to comment Share on other sites More sharing options...
Mason Poston Posted April 15, 2015 Author Report Share Posted April 15, 2015 Actually the port width is 6.5 inches wide.. wider than i thought but can be changed if necessary. 48 inches is the perfect width because it was perfect width in the last box i built. Since the box will be in my covered bed the depth can be however deep it needs to be, size is not an issue. I cannot include pics for some reason but theyre in my avalanche midgate with the subs out the outside and the port in the middle. Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted April 16, 2015 Report Share Posted April 16, 2015 You can use photobucket or imgur to host pics and then post them here. I find imgur really easy to use. You say the box can be as deep as it needs to be, but we really REALLY need to have the actual number. Different people have different opinions on just what "size is not an issue" means, numbers don't come with opinions.

Broke_Audio_Addict Posted April 16, 2015 Report Share Posted April 16, 2015 His box is extending into the bed of a truck, basically a blow through. I'm doubting you could design a simple ported enclosure for those 15's that would take up that entire bed. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Skullz Posted April 16, 2015 Report Share Posted April 16, 2015 Best to go with rockfords own recommendations. http://www.rockfordfosgate.com/Support/BoxAdvisor.aspx Single sub ported dimensions are 18x28x12 with a 4" port 10" long. To do a pair just double the internal volume and use 2 ports of the same as recommended. The box would be 28x36x12 and put the ports between the subs in the middle of the box so the subs get tricked into thinking they are in single enclosures but with a common shared chamber. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
Mason Poston Posted April 16, 2015 Author Report Share Posted April 16, 2015 Im willing to build any box design that will give the p3s proper justice. The box can go up to 3 feet deep possibly a little more if necessary but i doubt that. I will post pictures trying the method ASAP Link to comment Share on other sites More sharing options...
