Robert8252 Posted February 18, 2011 Report Posted February 18, 2011 Just using those dimensions is over 9 cubes gross!! Why can't you get the port right? In Torres calc adjust your actual box size until you get around 7-8.5cubes gross and then put in the info for port size and length and sub displacement. 45s will be nice if you can but aren't needed. 2013 F150 Crew Cab Old Build Log Feedback 2013 F150 Equipment - Some Awesome Stereo Sound Making Stuff
BanginOnABudget Posted February 18, 2011 Report Posted February 18, 2011 Did your sub come with T/S parameters? if so, drop em, and i'll give you the numbers you wanna hear ;D im taking out my passenger seat, battery is disconnected, going to unwire and take out the three amps, take out the 70+ lb box, then the platform so i can crimp 1 wire. Almost as bad as those fegs that put those horns in their grills and roll down the street distorting the block.... 1990 Jeep Cherokee 2 Dr. Big-3 in 0g on Stock Alt.

dugee81 Posted February 18, 2011 Report Posted February 18, 2011 next time you make a box, use torres calc. much more accurate as opposed to RE 200a alt. by Excessive Amperage hc800 under hood & 2 Deka 9a31 in rear 1/0awg + big 3 SAZ 3000D HDC3 18" @ 2 ohm
Playa Named Joe Posted February 18, 2011 Report Posted February 18, 2011 a center port at the back, firing back. 8H x 14L and 32D. you have to make the port like a box, but gives you a little over 16 per cube for port area, and 6.9^3 before sub and bracing dis[placement. That should be perfect. should yeild about 32hz tuning 1994 Pontiac Grand Prix build

xXxOuTLaWxXx Posted February 19, 2011 Report Posted February 19, 2011 The 7.5-8 cubes is before displacement. After you add the port and the subs displacement it'll drop to where you need it to be. Punch those numbers in as the gross volume and then play with the port size till you get your net volume of around 6 cubes and I would tune to 30-32hz "i'd rather die like a man than live like a coward" quoted from Tupac
mazdaspl Posted February 19, 2011 Report Posted February 19, 2011 What is the displacement of your sub?

manofthehour Posted March 15, 2011 Report Posted March 15, 2011 I've never been able to use Torres Calculator, too many spaces to fill lol, I use http://www.the12volt.com/caraudio/boxcalcs.asp to get the volume and port length and so on... Try that if the calculator is confusing you...
