I honestly dont see this formula being accurate. Maybe im not understanding what you are trying to do, but I think you are trying to use a mathematical equation to figure out how loud a vehicle will be?
Pretty much. I know it's not going to be very accurate, that's why I gave an acceptable error rate of + or - 5 decibels. Hopefully that'll account for the differences among vehicles.
I know it's probably a lost cause, but I can't get it out of my mind till I try. I'm like that sometimes.
I think he is trying to find an equation tieing together the meter, decibels, and wattage.yep. as close as I can. And it includes the cone area of the subs, too.
-
I'm working on a project to determine the decibel level of a setup to + or - 5 decibels. I'm using Meade's hoe as an example, and am getting close to my answer.
I just assumed it was .5" in diameter, and working backwards through my current formula, I ended up with the math saying Meade was putting just under 40,000 watts to all 4 of his subs. A lot, I know, but 2 hours ago, the math had him putting 500 kW (yes, 500,000 watts to his subs!) !!!
So, I'm def. getting close to having a formula on my hands.
I've been thinking about it for 3 days, I found a thread back in the near end of the off topic section that got me interested.
I was going to bump it when I got the math right.

Ok, so I'm doing a little math project on the side and need help. I need to know the diamter of the pressure mic in a TL. I know it's not a mic per say, but I need to know the diamter (in inches) of the part that senses pressure.
thanks in advance.

Hulu.com , Fancast.com , tvshack.net
Hulu doesn't have it until a week after it airs, and they only show it for 4 weeks and delete it.

I'll try and get a vid of my pipes shaking my house windows tomorrow.
but the camera isn't that good (blackberry cam FTL).
-
Dam! That looks good. I like the screen. Now you can start watching tv again.
-
holy crap! To me all this shit is confusing..... Windows is so much easier
Same here. I had Ubuntu at one point, but got tired of it. I kept failing trying to get it to do what I wanted.
-
Thanks for the link. It worked great. I'm editing the vid now.

Can't wait for the build log. 'specially pics.

who ever said Pyle was that bad?
Ever hear of Hot Shots?
LOL.
On a side note, I have a 12" Pyle that I put approx. 300 (clipped) watts RMS on for 30 minutes without blowing it.

HOw much you use dpends on the product, your system the design of your doors and your goals.
Ther eis no real way to put an exact number on it
25% might be perfect, Maybe 50% or even 100%
It will take some trial end error but most peopl find that 6-10 sq feet per door is where its at.
Hope that helps!

Ok. Thanks for the info.

You've got a loose connection. If the area where the wire connects to the amp is hot too, then it's at the amp. But from what you've said, it sounds like a loose connection at the battery.

. I don't remeber the size. It's nice though.
That's a bit big for my tastes. I want one in my truck. I already have a 15" and held it up in diff. locations in my truck and it actually looks kinda small. LOL. I was wondering cause I wanted to retrofit a tahoe dash in my truck because the screen has a dang good place to sit.
Sorry to get off topic Steve.
-
probably not that much bigger unless you are trying to get super crazy on the fiberglass. Dont forget this thing has a frame around it so it looks smaller when molded in but the frame is still there.
I would say a 12 would probably be about the limit before the degree of difficulty starts to go up a little higher. I would have done a 12 but i couldnt find a 12" touchscreen with front buttons. I think i found one with side buttons (its been a while i think it was a 12).
Ok. Thanks.
-
Hey Steve, if you don't mind my asking, how big of a screen do you think you could fit in that dash? Possibly 15.6"? I have an idea for my truck, and would like to know.
-
Awesome! The touchscreen looks really cool.
-
And order 10% more than you think you need. Trust me...
-
Just now? *becomes more paranoid by the second*
-
LOL. I'm amazed they still play.

Ok, so I took a vid on my blackberry and I just found out that my video editing software doesn't support the file format my blackberry uses. It was saved (and transferred) to my computer in a .3GP format (WTH is that?) and I need some free software to convert it. I'm running Windows 7 Home 64 bit and Cyberlink Powerdirector Express (got it in '06, LOL.). Does anyone know any free video conversion software?
Has anyone ever used this video converter:

If so, is it good?

I think I'm gonna keep him and take him to all of my 2010 shows
Other ones gonna see a wall socket.

What are you're future plans for Frank?

You could make a custom metal rack. That would allow you to use some kinda thick metal tube and plates plus heavy duty bolts (don't break the amp
). It shouldn't be expensive if you know how to weld decently.
Thanks for the link. It worked great. I'm editing the vid now.

LOL. What, the thread or my though process?
BTW, I think I'm even closer. Assuming the TL mic is approx. .3" in diameter, then the formular works! I'm kinda happy, but don't want to celebrate too early.
Thanks man.
And that info completely blows the formula out of the water. LOL. Oh well. But then agian, maybe not.
Oh, and yeah, SPL is logarithmic. That's part of my formula.
