kool thanks...will keep that into consideration the night before the comp (i dont have anther vehicle to let it sit for 2 days...always running around haha)
but why do you hate automatic chargers?
I had an automatic charger and it would always top out at 13.2 volts when it said the batteries were 100% full (which they weren't).
The manual charger will always go above 14 volts, even with the lowest setting. And even if the batteries to to 100%, the voltage stays at 14 or higher.

I hate automatic chargers.
Anyways, the slower the better when it comes to charging. I always charge my batteries for a couple days before a show with a 2 amp charge. Gets them to hold a charge very well.
Higher amperage is good for quick bursts of voltage, but it doesn't "fill" them up to 100% capacity.

Allowed in extreme. That's it.

Superstreet is unlimited batteries.

Sounds to me like he popped the fuse between the front battery and the kinetik. Check the fuse, even if it does look ok it still might be blown.
That or there's a disconnected/cut wire somewhere. When two batteries are hooked together they should read the same voltage. He's probably been trying to run his amp off just the kinetik which has pretty much killed the battery.

The safari you are referring to is dennis champan's M5 car. 4 crossfire xs spl 15's and 4 crossfire 2400d's. Did a 157.9 @ the headrest.
I was there competing in the s-10, but I'm pretty lowkey.
150.6 @ 41 hz at the headrest with the new single 10" box. Not sure if anybody from the forums saw my truck.

It's winter time. If any shows do arise it won't be until summer time.
I know there are some shows planned for indiana, but nothing set for illinois yet.
-
That is subjective.
DD dominates in SPL competitions across the world. They aren't too shabby for daily driving either.
-
For deathmatch db drag style, you actually use a test tone for the entire duration.
-
Wow thats a tight fit, but I guess that's to be expected when you have 4 times the normal amount of something.
And that's got to be the longest fan belt I've ever seen.
-
He has horns underneath the truck.
And now he actually has 10-12 mids in his tailgate. I believe he's got around 10,000 watts on his mids/highs.
-
Amateur has limited batteries.
Street has unlimited batteries.
The fusing that is used to determine your class has to be within 18" of the amp. Any other fuses do not matter.
-
I'll be there with some type of setup.
-
No because they are a solid tone with a beat over them.
-
It's early in the year.
Most shows won't pop up on the schedule till at least spring time.
-
Id pick you up at Orlando, but my van will be full. :censored:
Anyway, Tommy McKinney won that year. If Im remembering correctly, both cars bassboxed over a 160. 160+ is so sick in that format. The AVERAGE over 1 minute was over 160dbs. Now thats just so badass its not even funny.
Yeah i'm trying to work something out.
I was already offered space at an ocean walk condo....

Man I really want to come down.
My only problem is getting from the airport (orlando) to daytona.
25 years old to rent a car FTL.
Plane tickets into daytona direct are anywhere from $150-200 more, and have stops. Gay.
-
Both work fine.
You won't be able to hear an audible difference.

I have a regular truck install, In a 98 eclipse spyder,
and i have 1 - 10"
i be leave im using a 190 amp fuse, or something that close - i forgot, have to look.
i have been able to use a 60 amp fuse for like 20 sec's till it pops,
....... so is it that i want to run the lowest but best fuse i can? to be higher in that class style. ?
im a little confused where as of now i would fall in?,
i assumed i would do good providing they had a class of 1 - 10" woofer, or something..
let me know,.. thanks a lot.
What style fuse do you have for you amp?
Jeremy forgot to mention that for the pressure class you HAVE to have a fuseholder within 18" of the amp.
-
Thats not a daily driving capable setup though, unless you like to be crammed up against the steering wheel.
(btw, for anyone who doesn't know, thats my competition setup pictured)

Actually, you both are only partially correct.
What you need to do is test a sealed box inside AND outside the vehicle. That way you find out the baseline peak for the enclosure itself. Put the db sensor a foot or two away from the speaker, then play 20 to 80 hz one frequency at a time and write down the SPL score
Then you take that enclosure, put it in the car, and run the same frequencies. Write down these scores as well.
Now what you'll do is subtract the ambient (outside) score at each frequency from the in-vehicle score at the same frequency.
The frequency with the largest difference is the vehicles resonant frequency.
Simple example
35 hz outside vehicle=115 db
35 hz inside vehicle=135 db
difference is 20 db
40 hz outside vehicle=117 db
40 hz inside vehicle=140 db
difference is 23 dB
In this VERY simple example, 40 hz would be the resonant frequency.
To sum it up, the resonant frequency is the frequency at which the vehicle itself will increase your dB level the most. Sorry if I didn't explain it simply enough. Even with this though, you still have to do LOTS of testing in the vehicle itself with different size/layout enclosures to find out the best combination. And by doing this your peak frequency may change.
The bottom line is that finding the resonant frequency will only get you so far.

Haha i rember the first time i saw you do that zack, at the HD show in kent. I was like wow hes got some control with that thing lol. So far i think everyone has included the basics here
As far as material you also cannot modify a track by slower/speeding it down or up. Also cant "add" any background tones or anything. But you can play it back on any source unti. I think jay thompson (think it was him) bassraced with his laptop cause he didnt have a HU installed yet haha.
Also no rules as far as enclosure or equipment location, as long as it does not interfier with the mic. Everything must be sealed up and only one peson (the competitor) may be aloud in the car..pretty simple rules and tons o fun
As far as I have heard, you can slow a track down if you want to.
The only thing thats not allowed is a straight solid tone, which can be seen on the frequency readout on the termlab.
-
Damn, it looks like you could have gotten away with one of those LED's!
Good work as always.
-
bar graph says 158 score says 152
That's because the termlab averages out the 3 loudest frequencies.
Notice how theres 3 tall bars there? Two of them are below 152 and one is at a 158. Those numbers averaged together produce the score.
Here's another pic to show you what I mean. This is a score from my truck at 44 hz.
Notice the bars again?

I might try and do this just for fun even though I know they are probably doing to do it db drag style and my truck sucks sealed up.
We'll see.
