noodlebot Posted March 8, 2012 Report Posted March 8, 2012 Hey, so i have a 05 civic sedan and i want to put 2 12'' lvl 3 dcs in the trunk. I want to do subs forward port through the rear deck, although I have never built a box with a cylindrical port yet. I was wondering if the shape of the box really matters or I can just get my volume and put a port in. I wanted to do 3cu.ft. net volume. tuned to around 35hz (open to suggestion) sub info http://www.dcsoundlab.com/level3.html Also does it matter how much of the port is outside the box? because it will be poking out a bit to make it through the rear deck. This is what I came up with, is this a good diameter etc? When I put in a 4'' diameter the length was 6 inches so that didnt seem right. This wedge will be rotated 90 degrees. The subs will be parallel with how the seats lean back any advice would be greatly appreciated. I made this thread quick so if i missed anything let me know. Quote
LoudBimmer Posted March 8, 2012 Report Posted March 8, 2012 Use Torres calculator. It's better Also try to use 6" aero Quote
412 CVX Posted March 8, 2012 Report Posted March 8, 2012 download torres like stated. keep about 8-12 sq inches per cube of port area Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.
noodlebot Posted March 8, 2012 Author Report Posted March 8, 2012 I have a mac so I cant use torres....... I remeasures and need the width to be 35''... if anyone wanted to put that stuff into torres and post a pic here... Quote

Yes exactly. I want the end of the port flush with the rear deck. Will I count the entire port length for this or just the port inside the box? and is this a legitimate way of having the port. Quote
Joe X Posted March 9, 2012 Report Posted March 9, 2012 (edited) It's a perfectly legitimate way to run a port but you need to make sure that the box is bolted. The entire length should be used to calculate the port but the port displacement is only for the part that's inside. Edited March 9, 2012 by Joe X Quote
Jman08 Posted March 9, 2012 Report Posted March 9, 2012 Its easy use the 12voltbox caculator and go to psp-inc.com to figure port tuning. Would use 1-2 6's Quote Youtube.com/J Hutch22
412 CVX Posted March 9, 2012 Report Posted March 9, 2012 for two 12s?? single 6 or 2 4's should do. 2 6's is too much more than likely Quote Just say no to Ground Pounder Customs.
