Amp Strapping Question

[loburbon]

see this is where im gettin thrown off. the 9518 says it calls for 6cuft with 120sqin. but everybody i've talked to said thats too much. also i dont have my yukon any more. so no barn doors. this box is in a 2000 2dr s10 blazer. i had no problems getting my yukon loud, but this blazer is a whole different story

It calls for 5 cubed after displacements.

We are a dd dealer at the shop I work for, and ive ran DD's for about 7 years.

So for what its worth, Id try my box I said for you. Or else call up and talk to Steve and see what he says for it.

[audiofanaticz]

Blazers are actually easier to get loud, subs up port back is not always the loudest tho. So because you got a suv dont be stuck on a crx style box

And if my box isnt louder, your only out $30 bucks, and on to trying something new, but thats the fun part to audio.

i'm a dd dealer myself and i've never had this much trouble with a box. on the dd site now it say 6cuft and 120 sqin. yet before it was smaller. the 9500 series are the only one's that are like that. and i wont be out any money if the box doesnt work, i have more then enough wood layin around. i'll build a box anytime, i enjoy it. i'm just confused on why there site says something in one spot and something different in another

[loburbon]

it says 5cuft with 80sqin here

Volume # & size of Drivers Port Area & Length

5.00^ft (3) 10" or (2) 12" or (1) 15" or 18" 80.0 sq" vent x 18" long

but here it say different

im always up for a better box design by the way. i will give it to the box that's in there now, it sounds awsome. it hits the lows like crazy.

Thats for a G series 9500. I have no idea what you are running. However Id go with 5 cubed.

But that is besides the point..

Its fact that a larger box will make the speaker louder with less powered because its more efficent, where as when you toss more power to your speaker you need a smaller box.

Do you know how big Dantes box is? Its under 3 cubed if i remember correct and its doing big numbers with lots of power.

More power less box.

Im just trying to help and took the time to mess with some numbers and it seems like you dont wanna try anything else.

If you dont want to try new things and are going to be stubborn why bother posting?

[loburbon]

ok i said i wont be wasting wood, then i also said i'm always up for a better box design. which means i'm going to build the one you said. as for seeming like i dont want help, thats not it. i was just trying to figure out the reason for the difference in specs. and yes i'm running a g motor sub. i ordered two of them to run in my ranger on the 2 m3's. but someone wanted the ranger more then i did. i always try to look at every angle. like i said i havent messed with 18's. the box thats in there now does sound good, it just isn't good enough.

[audiofanaticz]

I didnt see this til after you edited your post.

im always up for a better box design by the way. i will give it to the box that's in there now, it sounds awsome. it hits the lows like crazy.

The box calculator im using is one of the most accurate ones online made by Expo Sport on these forums.

And with your listed dimensions of your current box, your port failed bad.

Im also bringing some of the specs on this box from a PWK design that I just got. Its almost half the size for my 2 9518s Im building soon.

You can get his calculator here, and do some number crunching for yourself.

And if you get really curious try out some of the other online "box calculators" and notice the change in tuning freq for yourself using the same dimensions.

[loburbon]

i've tried his calc and i dont know if it's my computer or what, but i can never get it to work. it always gives me crazy low tuning like 10hz. and i tried a few box calculators and your right they are always different.

[audiofanaticz]

It works fine on my end..

As it says in his post make sure your windows is up to date with the latest framework and what not.

Click on your start bar, and goto update windows, and when your at the windows site, select custom install, and check mark almost everything that it lists (except for stuff like monitor/video drivers, sound drivers, eithernet drivers etc cuz that wont matter).
