Torres Posted July 28, 2007 Report Share Posted July 28, 2007 (edited) i am going to get 4 15" fully loaded BTL's and was wondering what the best box to put them in would be. 5 cubes by themselves ported? i always heard it's best to put them in their own box or if it shares a box, to put a separater to separate the subs. but lots of vehicles i've seen lately have 2 to 4 subs in one BIG box. any differences in the two? should i put all 4 in a box with about 20 cubes and brace the hell out of it? if so how big should the port be? i have a lil more than 20 cubes of airspace available. nothing bigger than 42"W x 33"H x about 40" long. i also heard that it's loudest if subs face up, and port faces back. but with 4, i'm probably going to have to wall it off. it's going to be going in a daily driver that wants to compete can anyone help me with box/port dimensions? i just want the best build possible. if you can i'd love you forever Edited July 28, 2007 by ExpoSport Quote Link to comment Share on other sites More sharing options...

Also, a street box and comp box are not the same, one your building for ground pounding(street) and the other (comp) is for the mike/sensor.not your ears!! depending on how serious your gonna get, I would stick with the street build, it would sound better. Comp boxes are made for 1 note/freq. If I'm wrong, I'm sure someone will correct me.

Torres Posted July 29, 2007 Author Report Share Posted July 29, 2007 yeah i knew there was a line between straight comp boxes and daily boxes. was curious as to if there's a safe mix between the two. maybe a removable port? single boxes, or two boxes with their own chamber might be better, just as far as fitment in concerned. opening in the back isnt quite as big as the inside of it. so maybe i'll build two separate boxes. thanks for the tip. there's a LOT i dont know about box design. i see some seriously complicated boxes and just think ???

Did some more checking, as for ports, you can do changable ports, the would be your best bet if you want to walk the line between comp and street.

No need for 2 boxes!! 1 box, changable ports. Unless you just want to build 2 boxes Quote www.competitionsoundz.comTeam R&RTeam MaxxsonicsTeam DC AudioTeam PowermasterTeam KinetikHooker car audio Link to comment Share on other sites More sharing options...
Torres Posted July 29, 2007 Author Report Share Posted July 29, 2007 No need for 2 boxes!! 1 box, changable ports. Unless you just want to build 2 boxes just depends on fitment issues. one box would be easier as far as work, 2 boxes be easier fitting in cuz the opening in the back isnt as big as it is inside. but i might have enough room to lower it a couple inches. just make it a tad longer. hopefully tomorrow i can get out and get some measurements done. might need all the heighth i can get, it's like 34 inches from the top to bottom. but yeah...i'll check Quote Link to comment Share on other sites More sharing options...
