Jared420 Posted October 29, 2009 Author Report Share Posted October 29, 2009 as long as you can equal the port area you need you can use as many smaller ports but then it gets really tricky. what program did you use to figure that out Ill check it out and see what I can come up with i could do some really long 3'' diameter ports maybe. but what frequency would you guys recommend i tune it to?

One site told me 2 3'' diameter ports 2 and 3/4 in length will tune to 38 hz? should the ports be longer than 2 and 3/4 inches?

barros57 Posted October 29, 2009 Report Share Posted October 29, 2009 wait, so you have 4 dual 2 ohm subs..could you wire them to 4 ohms instead of 1? I think it would make the amp more efficient = less power draw. At least it would help with the dimming of your lights ans stuff.. ha im having a hard time visualizing how the wiring would work for 4 subs Quote My 93 chevy truck Orion HCCA 15's Build 6K HID's 2 orion HCCA 15.4 2 AP30001D's 2 optima yellowtops, 2 C&D 270fr's, all 3 tsunami 1/0, CS144 190 amp Rockford p200-2 Rockford p200-2 Rockford p300-1 Kole KX1 5500D -broken Link to comment Share on other sites More sharing options...
