hi guys got a question im looking at building me a box for my car for my 2 12inch kicker L5's. but the problem i have is im not to good with math to where i can come up with a good size box. and was wondering if i were to give somone the info of my car space and what cubic feet i need the box to be. would somone beable to come up with the size of each pice of wood i need to cut out. because i can put the box togeather thats not the problems its just coming up with the sizes of the wood i need to cut and how many pices i need to cut is the problem. i built like 2 boxes for my past system i had befor but the guy i knew who did all the math and stuff for me move and now i have no way of getting hold of him.
yea right now the box i have which i got off ebay is said to be tune at 38hz so yea i have no ideal about tuning lol alot of people i know tune there amps and stuff to 40hz if only i knew a good tune to go with i mean if im right i belive i seen a setup with somone with a 6.50 cubic box tune down to like 32 or somthin like that
i see well looking at what you have done the death is a bit to long. for the space i have because this is what i have for space tall 34" x deep 19" x wide x40" and after the box is built. i should have 3.25 cubic ft per sub which comes out to 6.50 cubic total with a divider and for tuneing i talking to someone i know and he said he was thinking 38hz as well
If you have a table saw you can just set the blade on a 45 degree angle and cut it and then switch the piece of wood around and run it through again so you have cut the two side to 45 degrees. then the piece should fit in the corner perfectly.
If you do not have a table saw you can do the same thing with a circular saw its just alot harder to do
k lol was looking at what u gave me for each pice of wood which i thank you so much for u been so much of a help to me. but im a little confuse here sorry when u say deep tall and wide what do u mean ? all i know is if im right for 2 fronts 16 tall 16.125 wide is 16 x 16.125"
k so just make four 45's for each corner of the box ? or is this picture post to be what it looks like if u were to look inside it without the top on to where all i need to do is put 2 45's on both top corners and not the bottom corners
When i say wide for your bottom and top i mean that the board when in the vehicle is going to span the width of the vehicle (from side to side). When i say deep or depth i mean from front where the speakers are mounted to the back (near the back seats. I hope that helps explain it
yes it dose lol thx now i edit the pic u sent me of the box is this how it should look now or do i need to add the 45's at the bottom of the box to on the back because i can make 45's off some 2x4's at work if i have toside
yea from top to bottom. To tune it to 38 hz your port needs to be 22 inches long. that means that you need to curve the port so your 2 port walls will be 16 inches tall by 20. Then you need to add a 2 inch piece to go join the two ports so that you get the 22 inch port.
sorry i dont understand what u saying u lost me there about the part when u said .that means that you need to curve the port so your 2 port walls will be 16 inches tall by 20. Then you need to add a 2 inch piece to go join the two ports so that you get the 22 inch port.
You need two pieces for each port. One is going to be the main wall of the port(16 tall piece x 20) the other piece needs to be 2 long by 16 tall. The second piece you will screw onto the first piece to form a L shape.
Picture yourself looking down from above the back of your box with the top off your port will have the one center piece and on the left side you will have a backwards L shape to the right you will see a regular L shape.
k i think i have the box down now cool let me go over this to make sure i got everything.
2 pices of 24.5 x 16 for top and bottom 1 pice of 16 x 40 for back 2 pices of 16 x 20 for the I sharp part of the ports 2 pices of 16 x 2 for the L part of the ports 1 pice 16 x 22.25 for the divider 2 pices of 45 degree pices that go from top to bottom for both back corners
after everything put togeather with subs in box i should have a total of 6.50 cf with 3.25 cf per sub tune to 38 hz
