possible to get a hairtrick? maybe someone could help?

[fecupe2001]

Exactly! I hit 147 with a low tuning and did hairtricks, the explorer it´s over 150 and can´t move even a toilet paper haha

i have to disagree. i know a few guys with 1 18" or 2 15"s doing 145-147db and they can do hairtricks. on music i could do 149.5ish and i couldnt get a hairtrick. i burped a 150.4 but never did a tone with a girl in the window.

hey skittles, I finally got just a hair over your score, i got a 150.5 sealed up on the dash @ 41hz. no vid or pic though cuz i was doing power testing and just writing it all down.

and on topic, i also did a half ass hairtrick with a single 15, in a 2 cube box, 22hz tune, 25sqinches of port, on 3k. It did the trick at 20 hz,

22 hz tuning??? damn!! i bet it sounded like crap over 40 hz hehe, just a moving hair box right?

It actually did pretty good, peaked on the termlab at 42hz i think with a 144.4 i think. I did a 140.1 at 25hz.

It was a mess up box that turned out real well. It was an attempt a a tline before i knew all the rules to building one

Damn, very flat respond!! That´s nice, i´m gonna build a box for moving hair, but nothing below 35 hz tuning i guess, don´t wanna loose the 40-44 hz that i like so much

How do you even find out what to tune your port too?..I wann learn how to tune ports and i want to learn about port area.I've built some ported boxes and they seem alright but i have no clue what they are tuned to or anything..lol I'm planing on going a lot bigger this summer when i get my next car that i will keep a while. I need to learn about ports, so if anyone has suggestions,tips, or wanna help me learn. I would appreciate it greatly and you would be helping me a lot.

Its all about low tuning and power. I'm doing a hair trick with just 2k and 2 12's. I hit 140s

what kind of 12's

DD2512s there not broken in cause I barely have enough power to. lmao

[fecupe2001]

Well, there´s a very simple rule on port area, 12-16 SQ of port per each cubic feet, it´s very good if it´s a simple box, but there are subs that likes smaller, others bigger, for example, my DD´s LOVE at least 16 SQ of port per cubic feet; Also, depends on the power, if it´s a small power you don´t have enough for a big port and viceverse.

Said that, you find out how much internal space you want for the box, you get how many SQ of port you need, and the tuning just use the12volts.com or any other online calculator for the port depth, that´s pretty much it, of course, it´s way more complex than that if you are competing or something, but for a simple box, that´s the easiest way...
