99xtremedime Posted January 21, 2010 Report Share Posted January 21, 2010 Ok I will soon be buying my BL 18 when income tax comes in, and I've been using exposports box calc. ALOT coming up with designs and I think I found the best one so far. I just wanna know you guys' opinion that know more about this stuff than myself. Ok, box external dimensions are 46W x 26H x 16D and i got a gross volume of 8.56 cuft. Slot port internal dimensions are 14H x 6.5W x 15L, and including the 0.26 cuft sub displacement i got a net of 7.46 cuft tuned to 33.16. How does this sound, it should definately LOVE the lows yet still play clean highs and get LOUD (hopefully close to 140ish???). Oh yeah and the box is sub forward port up on the driver side, and for bracing I'll use 1" dowels to save some space and the front will be double baffeled with a countersunk sub. Material will be 1" MDF Quote -2 AQ HDC3 15's-'Nendo 3KWP @ .5-7.75cuft @ 30hz-Alpine CDA-117-4 Cadence PA 8's -AQ 200.2-2 AQ Supertweeters-XS Power D3400-270a Mecman Alt -Knu Konceptz Wire Link to comment Share on other sites More sharing options...

In my opinion though, I would try both your idea and also sub up port sideways to see which yields a better sound. Should pound nicely. I wouldn't be surprised with that setup hitting a 140.

Yeah i hate it when a noob thinks they can just buy an 18 and slap a box together and hit 160! lol But when you say port sideways you mean facing either the driver or pass. side of the truck right?

Depending on the position yes. Hell, I would try all three if your design allows. It's all trial and error and you might just be surprised with the result! Quote Need an install?

I'll will most likely do all 3 and try them on my buddies TL, but for now im gonna build the said box of one that someone else designs if they do and run with that for a while. I'm just to get away from a Sony Xplod 10 and .65 cuft sealed box....... lol (came with my truck back when i bought it btw... not my doings!)

Hostility Posted January 21, 2010 Report Share Posted January 21, 2010 (edited) I'll will most likely do all 3 and try them on my buddies TL, but for now im gonna build the said box of one that someone else designs if they do and run with that for a while. I'm just to get away from a Sony Xplod 10 and .65 cuft sealed box....... lol (came with my truck back when i bought it btw... not my doings!) i think your ports wrong. if your box is 16" deep (you must not be tall because in mine 15" is max i can go. lol) and if your box is 16" deep, port up, your port would be 14.5" (.75" on each side for the wood) unless your using 1" mdf. but the 18 will do nice in there, dont port sideways, its only good for smaller box's. sub forward, port up!! Edit: sorry just re-read, you are using 1" MDF lol.... carry on hahaha Edited January 21, 2010 by Hostility Quote 99 s10 4.3L Big 3 220amp alt Odyssey 1500 Odyssey 2150 Northstar NSB 75 Sundown Audio 3500D Sundown Audio 125.2 3 Sundown Audio SA-12's Alpine H/U RF Power Comp set 6.5" RF 3 sixty line driver 5.25 cubes @ 31hz Link to comment Share on other sites More sharing options...

Yeah luckily i got the 3rd door which help ALOT, and as far as seat placement goes it will be a little close but i surprisingly have enough room to lay my seat back quite a bit. My buddy is 6'1" and he can still fit in it, a little cramped of course, with a mock up cardboard box we made.
