RobertMcDonald Posted September 3, 2011 Report Share Posted September 3, 2011 FIrst off I would like to thank Forevrbumpn for his tutorial, w/o it I probably would not have undertaken this project. So, I decided one day that I wanted to build a T-line for a buddies car, it housed a single 12. Once I was finished with it, installed and listened, I knew right away that I must have one, it sounded amazing and produced tremendous bass for what it was. So, I went to the hardware store and purchased a butt load of glue, screws, and MDF. I started building on Saturday morning at 0600 and had the box installed on Sunday night. It wasnt complete, but it was close. I just had to see what it sounded like so I installed it. Ok, the box is 17 cu.ft with exterior dimensions of 62"w x 33"h x 28"l and houses 4 Skar Audio vvx-12's. The line is 9 feet long making it ~32hz tuned. It is a tri-fold with a port of 5" x 59". Its slightly small, ~20 sq.in. I placed this behemoth in a 06 dodge ram quad cab, but its not in the cab. I cut the bed and cab open and placed the box in the bed. Its a blow through, this way I can still haul my kids around if necessary. Ok, enough with the talk and on with the videos. Sorry I dont have progress pics or vids, I am single minded when it comes to working and normally dont stop until I drop or the project is finsihed. Ok on with the vids.

IH8PunkRok Posted September 3, 2011 Report Share Posted September 3, 2011 you have 295 sq inches of port. for four twelves you need around 400. did you do this for power handling? im curious Quote -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
RobertMcDonald Posted September 3, 2011 Author Report Share Posted September 3, 2011 you have 295 sq inches of port. for four twelves you need around 400. did you do this for power handling? im curious Mainly I did 295 because of space, there simply wasnt enough opening to allow for the 125%. I was under the impression that the SD of a 12" woofer was ~76 sq.in, is this wrong? Quote My link Link to comment Share on other sites More sharing options...
Torres Posted September 3, 2011 Report Share Posted September 3, 2011 no, it's ~100 sq inches per, depending on what radius you use to measure (5.5, 5.75, 6, etc) Quote Link to comment Share on other sites More sharing options...

RooTxBeeR Posted September 4, 2011 Report Share Posted September 4, 2011 Np dude, Those guys that are talking about the calculations know what they are talking about when it comes to boxes. If you didn't have space to have it proper, its not a error but what ever.

The hole is 59" x 19", only a couple inches left below the glass. Looks like I have to fiberglass the box, the bed liner isnt sealing it well enough. I will Start with the top and see how that does. Anyone know if I have to use the matt or can I just use resin to seal it? Quote My link Link to comment Share on other sites More sharing options...
