SDMorris Posted April 30, 2010 Report Share Posted April 30, 2010 So my previous box I just built last week for my truck ended up not working and one of the walls broke causing the box to pretty much be trash. I am trying to design a box for my Ford Ranger. The maximum depth the box can be for me to still sit comfortably and drive is 18 inches, and the box cant be much wider. It can maybe go an inch or two wider and an inch or two taller. I am looking to be tuned around 32-34hz. The subs I am using are two 15" Level 3s, and they will be mounted inverted. Does this box look good? I am not sure about the port, do you think I'll get any port noise with it being only 3" wide? Thanks for the help.

hdorre Posted April 30, 2010 Report Share Posted April 30, 2010 You should have 12-16 square inches of port area per foot. Also, I would Make the port height 20.5 inches tall because it's easier but it height will work too Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...
SDMorris Posted May 1, 2010 Author Report Share Posted May 1, 2010 Ok so how would I go about increasing the in^3 of port area, decreasing the box size? And making the port 20.5 inches tall won't affect it with the port being so close to the bottom of the box? Sorry I really suck at designing boxes :/ could anyone design me something using torres calculator and post a screenshot? I'd appreciate it.

Guest Posted May 1, 2010 Report Share Posted May 1, 2010 make the port bigger, or wider in your case Quote Link to comment Share on other sites More sharing options...
OBI Posted May 1, 2010 Report Share Posted May 1, 2010 Might not look super pretty. But have you thought about having a an external port, would work better with aeros though. Quote Link to comment Share on other sites More sharing options...
SDMorris Posted May 1, 2010 Author Report Share Posted May 1, 2010 Here's my problem, when I get the square inches of port per cubic foot to around 12, my tuning is way higher then I want it to be, like up around 38-40hz, and im trying to keep my box at 32-34hz. What I am doing wrong here? Quote DC AUDIO 06' Lancer Link to comment Share on other sites More sharing options...
Skullz Posted May 1, 2010 Report Share Posted May 1, 2010 (edited) Switching to round is 9 to 12 and aeroports are even less, so switching to a more efficient port can help you. EDIT: round port of 2x6"x18" with a .3 dis will put you at 34hz and a net of 5.5 Edited May 1, 2010 by Skullz Quote 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

Im sorry I dont get what you mean by switching to round is 9 to 12.. Aeroports would be cool, but I dont know if I could even fit them. The port has to be on the top of the box with the speakers, and I cant make the box much wider then 34". What will happen if I dont have the proper amount of sqaure inches per cubic foot?

Skullz Posted May 1, 2010 Report Share Posted May 1, 2010 Round as in pvc pipe, exhaust pipe, carpet tubes, sono tubes and anything round with a hole in it to use as a port.
