Just wondering what you guys think of this design for a F150 Blowthrough with 4 15's AA Chaos on 3500-4k watts. Will this hit the daily lows 28-38hz area and do good for daily music also any kind of numbers as well??


If you have built a 4th order with good re****s then please post any helpfull tips or information you have for me. I wont say and please no one say who this box was designed by. Want to see what other people think to have several suggestions to get a idea of the ideal box.

Not sure if I should do 1" or double 3/4MDF?

Did you tell him what kind of sound you were looking for before he designed it for you? If he designed it with your goals in mind, which I'm sure he probably did, then it should work well. Just build it and test...that's the only way you'll know if it will satisfy you or not.

yea use 1inch wood double baffle the wood the subs mount on and use 2x4's (about 8 of them 43long) goin across the top for added bracing in the ported chamber and u should be fine

if someone desgined you the box then they should have entered the t/s parameters into your program and then you can adjust it to suite your tastes, simple as that

I've been wrestling with 4th orders in a van for the past 2 yrs. and I'm not quite where I would like to be yet but I'm getting there. They are not easy on a large scale.
