IKnowImLost224 Posted March 6, 2012 Report Share Posted March 6, 2012 I have been hearing aero ports are the way to go. I don't have a whole lot of space in my trunk (2001 Malibu) and I want to make a box with aero ports for a 15" XXX. That being said, I have absolutely no experience with aero ports in any way. What I want to know is... How do you decide on the placement of the ports? Should I do sub to trunk lid and port to driver? Or both to trunk lid? How do I know what size aero I need and length? Held in place by glue? If so, what type? Do both ends need flares? Would there be any way of saving the box pictured since I made the port too small? I need about 4 cubes and I want to tune it to like 36 Hz. Max dimensions are like 34"W x 16"H x 20"D Box plans and any tips on how to make them would be greatly appreciated. I have made normal L ported boxes using Torres so I know how to make them, but thats about the extent of what I have done. Link to comment Share on other sites More sharing options...
Joe X Posted March 6, 2012 Report Share Posted March 6, 2012 Here is a slot ported suggestion that will be louder than the box you have, aeros are no good option for your dims. Enclosure Specifications: Fb = 36.094 Hz Vb = 4 ft^3 External Height = 16.5 in External Width = 34 in External Depth = 20.5 in Port Width = 4 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Front & Back (3 parts) = 34 x 16 1/2 Left & Right Sides = 18 1/4 x 15 Top & Bottom = 34 x 18 1/4 L Port Internal Assembly Parts: Front to Back = 14 1/4 x 15 Extension = 2 1/4 x 15 Let me know any questions.

Lbox88 Posted March 6, 2012 Report Share Posted March 6, 2012 So here are a couple things I have picked up from others as far as aero porting: -keep port volume between 8-12 in2 per cube of port area -end of inside flare must be at least 1 port width away from the side of the box Typically in a trunk build, most people have the best luck either putting the sub back or seal it off facing forward with port forward. Port size/number/length is chosen based on getting the proper port volume and desired tuning. Flares are used on both ends to get optimal efficiency from them and to avoid port noise/chuffing. Many aero ports come with one of the flares read to be screwed or glued onto the box. I feel a little less retarded today and re-did that box I made before but with real sized aero ports than you can buy at parts-express lol. This is what I came up with UBL | Build Log Link to comment Share on other sites More sharing options...

This is what I came up with Now would I put all 3 ports next to eachother? And do both ends come flared on ports you buy from the internet? Also is this something you have tried in your malibu? I believe we have close to the same trunks, i have a 2001. Link to comment Share on other sites More sharing options...
Lbox88 Posted March 6, 2012 Report Share Posted March 6, 2012 dammit, didn't think of the flare outer diameter. Our trunks should be the same, no i haven't tried it in mine, and yes the ports come with both ends flared from parts-express.com i believe. Search "ports" at PE and you can see them. Might not fit with the flares. Imma just quit now since i fail at aeros evidently lol. UBL | Build Log Link to comment Share on other sites More sharing options...
Joe X Posted March 6, 2012 Report Share Posted March 6, 2012 Aeros can be purchased from partsexpress.com BUT this is a 54mm Xmax driver, you NEED more port area. Link to comment Share on other sites More sharing options...
pimpnFosgates Posted March 6, 2012 Report Share Posted March 6, 2012 i use pvc as aeros. flares are like adding the45 to the slot port. u dnt need it, its just better. you buy pvc, heat it up on some round objeccct and push down to make it flare out. its what i did for my box but no flares.

StrongmanDesigns Posted March 6, 2012 Report Share Posted March 6, 2012 I built a box for a XXX using a 6" aero port and it did very well. I also built one using a kerfed port with much more port area and it also did well but I'd say the extra port area was not necessary. Link to comment Share on other sites More sharing options...
chrishova Posted March 6, 2012 Report Share Posted March 6, 2012 I have a Grand Prix with similar room and a SMD 15'' going on a SAZ3500 @ .5 ohms... What do you think? -and I saw the longer the port, the deeper the bass, can I use a PVC coupler and put on an extension for lower bass for daily driving? Pontiac Grand Prix GT400a Mean Machine alt.
