I want to build a new box for my 2005 Ford F150 extended cap.I have 4 DD 3500 twelves and a DD ZSE Amp.I wanna street beat more than spl.Anyone know the resedent frequency of my truck?

put a sealed box in and see where you peak at thats what ive always done every vehicle is different!!

If you want to street beat it doesn't really matter what your resonant fz is. You would want to build a box that gives the subs the flattest response curve or a possible bump around 40hz. Four 12"s would want 9-12 cu ft. , 100-150 sq. in. port tuned to 32hz-39hz.
I would think subs forward and ports up.

Tested 2 f150's a 2005 and a 2007 and both were at 58hz

I dont know about that res freq not mattering. Cause no matter what I tune my boxes too they are louder at my cars freq. An sometime it hass to do what song your using too.

yeah def agree with supa your vehicle likes a certain frequency no matter what your box is tuned to! at least in my experience. now i aint as loud as these guys so maybe once your get so loud it dont matter but it does to me!

That is not the case! I have built boxes that peak were I want them to! It has more to do with box size than port size .

Maybe it's a difference of opinions. What exactly is streetbeat? A system going 'bang,bang,baaang,baaaang,bang,bang,baaang.' At 60hz or something going 'boom, boom, booom, booom, boooom, boom'at 40hz? That is what's going to determine the design and tuning of the box.

Good way to look at it though anthony tell these young bucks dammmmit tell them...LOL i know what you mean bro one customer wants burrr burrrr burrr and the other wants BOOOM BOOOM BOOOMM.... fo sho i consider a streetbeater to be around 40hz but he means sb the class i think
