Fi BTL 18 enclosure

[Juice+ 0]

Ok, so i have figured out what i am going to get.

1 fi btl 18 and ma audio HK4000D with pioneer premier DEH-P980BT deck.

I need some help building a box, just need a very simple one

I have a dodge charger and the dimensions we have to work with are

31w x 14 1/3h x 30depth and MDF 1inch

since the height is only 14 1/3 i am going to have to slant it, can someone help me with a drawing or something, like where the top panel needs to slant in order to have enought room to fit the sub

please tell me what you think and if you have any advice please tell me.

Thanks, Madison

Do you already have the sub? If not it would be a good idea to get something like a couple 10s or 12s. Something like 4 nice SSD 10s would probably be the way to go.

But if you already have the BTL and really need to get it in that trunk, you can do it. Not sure how well it will work though. If you really take the time to design a real nice enclosure and recheck all the math thats the way to go, but if you're just lookin for a daily beater (Ha, I said "daily beater") you dont need anything special. Just a quick design from the RE Calculator would work fine. Its not exact, but Ive used it a ton of times and every system sounded great.

Actually, after just entering the max dimenions and getting a decent amount of port area, the box is going to be REALLY small for that sub. Id just run sub up and port back even though that doesnt usually work too well because you would be worse off with a slant beause that would give up even more airspace that you REALLY need. I know those are the dimensions in the trunk, but be sure you can get a box that size IN either through the backseat or through the trunk opening.

Personally, Id just sell it for as much as possible and get something that you can run properly. Something like 4 sealed SSD 10s in the right airspace off that MA amp would most likely do much better than the BTL thats being choked off in that tiny box. Just run a little 4 cubic foot sealed 1 chamber box. I could help you out with that and even do you a little design from Sketchup to show you what it would look like. Would be pretty simple to build in the trunk if needed. Would also save a ton of room for an extra battery that the MA amp will definately need and even room for the amp itself, since it doesnt exactly have a small footprint.

Heres a quick design I came up with in a couple minutes. If you feel like putting in the effort, it would be really beneficial to build assemble inside the trunk and use fiberglass to contour into the spare tire well and in the nooks and crannys to get every last tenth of a cubic foot you can. Id also just use 3/4" MDF and use threaded rod as bracing on the X, Y, and Z axis because using 1" MDF takes up a good bit of precious airspace.

In this link enter the numbers in red in this order, from top to bottom. 31, 14, 30, 30, .75, 5, 0. That will give you a real quick design. http://www.reaudio.com/speaker_box/LPort_Box_Calc.html

Hope that helps. If you wanna talk about anything feel free to PM me or send me an IM on AOL Instant Messanger at galacticmonkey0.

Best of luck to ya!
