bre2ts Posted March 7, 2011 Report Share Posted March 7, 2011 (edited) Ok let me give you all the info. I live in japan and they use the metric system for MDF so I try don't have quite 3/4 inch MDF. What they do have is 18mm MDF which is as close as I am going to get here. I drive a 1994 Toyota hilux surf (4runner). I am going to have a 270a DC Alt under the hood with an optima red top under the hood and 2 hc2400s in the back. This will be powering the new DC 5K amp. I am going to be running 2 DC lvl 4 XLs 15s. I want to build a box with subs up and port towards the back. I was wondering if some one could help me design a box or design a box for me. I do not want to invest all this money and not have a properly designed box affect the system from operating at optimal level. I would appreciate any help and input.

Carroot1 Posted March 9, 2011 Report Share Posted March 9, 2011 we need dimensions in inches Quote Link to comment Share on other sites More sharing options...
bre2ts Posted March 9, 2011 Author Report Share Posted March 9, 2011 1 inch = 25.4 mm 1 mm = 0.0394 in so 18 mm = 18 X 0.0394 in = 0.71 of an inch (just over 7 tenths of an inch) And since decimal inch rulers aren't readily available, you'll have to convert to fractional 16ths: Multiply 0.71 x 16 to get the number of 16ths inch. 0.71 x 16 = 11.36 11.36 = the number of 16th's of an inch. This is the numerator of the fraction. Apply the rules for rounding. 11.36 rounds to 11 because 0.36 is less than 0.5 Therefore, 0.71 in. = (approximately) 11/16ths of an inch Quote Feedback 1 | Feedback 2 you win some, you lose some Link to comment Share on other sites More sharing options...
