Fmxperson Posted May 26, 2012 Report Share Posted May 26, 2012 I have 2 sundown sa12s and im trying to move as much air as i can with them, like enough to do decent hair tricks, and i need suggestions on how much port space per foot i would need. im looking to tune the box at 29hz as that is what my current box is tuned at. Most likely going with an L-port design and subs up port up.

sprkn_ranger Posted May 26, 2012 Report Share Posted May 26, 2012 (edited) What kind of music do you listen to? 29hz is way too low IMO. And your probobly not gonna get hairtricks outta 2 12's. At least not good hairtricks.

An just cause one guy was able to in a trunk car doesn't mean anyone can do it. Its very dependent on the vehicle and install. Oh and can you link a vid of that hairtrick on those subs?

Thats what i want. im probably going to go with a slightly smaller box with a little more port area than the box i have now. the box is too big for the power im pushing haha Quote Team Audio Specialists 1998 GMC Sierra SLT Z71 ext. cab Headunit: Pioneer DEH-P7400HD Mids and Highs: One pair Boston SC65 6.5s One pair Boston SE75 4x6s Two pairs of Precision power T.2 tweeters Two pairs of ebay type tweeters (soon to be replaced) Boston GTA704 four channel amp RCAs: Stinger 4000 series 4 channel RCAs Lows: Two Sundown Audio SA-12s Sundown Audio Saz-2500d 3.9 cubic foot ported box (full 45 corners) fully braced and resined tuned at 33hz, all before displacement XS Power D3400 and Interstate starting battery, both under hood all KnuKonceptz Kolossus 1/0 wire (just 1 run for now) Big 3 done in 1/0 Audio Specialists <-----Best car audio shop in Western Kentucky/North Central Tennessee Link to comment Share on other sites More sharing options...
