JRminivan Posted November 26, 2012 Report Share Posted November 26, 2012 I just picked up 4 12" Soundstream Rubicon 12 for $80 and I want to play around with them. So I'm looking to build a box for all 4 12" It will be going in back of a 2005 Pontiac Montana with the all 3 row of seat in the van. I have max of 49" wide X 18" deep X 28-30" high. The back rest of the seat are 28" high but I'm willing to go as high as 30". They will be powered by 2 Phoenix Gold Ti800.1 so around 1600 watts rms. I'm thinking of either 2 subs per Ti800.1 @ 2 ohms or strapping the two Ti800.1 @ 4 ohms. I came up with do design for boxes and was wondering what you guys think. I listen to rap, hip-hop, r&b mostly but do occasionally listen to country, alternative and rock when the wife is in the car. The first box is made with 2 boxes with 2 12" @ 2ohms off a Ti800.1 Net 4.46FT^3 32.5 hertz port will be 28.5" high X 2" wide X 24.5" long The second box would be all 4 12" on the two Ti800.1 strap @ 4ohms Net 11.2ft^3 @ 32.5 hertz with a double baffle port will be 4" high X 20" wide X 10.75" long Any input would be great, thanks. EDIT: brace will be added and subtracted from the net volume after I know what box I'll be using. Soundstream says 1.5 to 3 ft^3 per sub. Link to comment Share on other sites More sharing options...

Daniel Shepard Posted November 26, 2012 Report Share Posted November 26, 2012 what is the port area? How to I figure that out? Take the inside dimentions of the port opening and times them by themselves.. box one has 57sq inches per box, box two is 80 sqin. a good rule of thumb is 14sq inches per cub of the box. I think you should go a bit bigger on your ports personaly Link to comment Share on other sites More sharing options...
JRminivan Posted November 26, 2012 Author Report Share Posted November 26, 2012 For box #2 I could go with 5" high X 20" wide X 15.33" long that give me a net of 10.79ft^3 with a double baffle. Or I could go with a single baffle and get 11.46ft^3. Link to comment Share on other sites More sharing options...
Truconcept Posted November 26, 2012 Report Share Posted November 26, 2012 isn't 32.5hz port tune kinda low for wanting to play all genre of music? **actin bad like a kid at six flags** Link to comment Share on other sites More sharing options...
JRminivan Posted November 26, 2012 Author Report Share Posted November 26, 2012 I will mostly play rap, hip-hop but when the wife and kids are in the van the bass is off so I guess the country and other stuff my wife like will not really be playing any bass. Also the wife doesn't drive, I'm the only one that drive the van. Link to comment Share on other sites More sharing options...
