If the equivalent combined cone area is more than 2 x 12" or 1 x 15", then yes, it will move them into STOCK B class.

QUOTE

Subwoofers not circular in shape, will be counted as there equivalent diameter size.
All subwoofers within the vehicle, operational or not will be counted.

That doesn't say anything about cone area.
But it says equivalent diameter size... is the equivalent diameter size calculated by cone area?

Looks like I may be running in STOCK B then

O well looks like I will have to build a new box cause of this gay window line rule.
I know there are some SQ cars that won't compete due to this rule
I would have preferred the hight of the front seat line

Why would SQ cars have enclosures higher than the window line ?

When's the first comp ?

So revision 3 Stock class seems to just of been modified to discriminate against square subs.

Are people allowed a single 15" square sub in STOCK A as its under the cone area of 2 x 12" round subs. And also 2 x 15", 3 x 12" square subs in STOCK B

for looks

Stock B is only allowed 1 battery aswell? Although Stock B is allowed double the amplifiers and double the subwoofers competitiors are only allowed 1 battery? Why not 2 batteries? Then onto modified class unlimited batteries allowed, surely 2 batteries in Stock B is a happy medium.

the way I read the rules at present, would mean that people with hatches cannot remove there parcel shelves????

Vehicle has to be roadworthy....does this also mean the the entrant must hold a current drivers license????

"speaker enclosure must be located behind the rear-most door jamb and muct not inhibit the normal operation of he vehicle"

i assume "normal operation of the vehicle" refers to being able to put passengers on the rear seat?

2 batterys would be good for stock b

Andu, i can't see where stock a rules exclude kicker squares,
if they do, the rules need to be fixed up.

Why in Modified 1-2 u cant have a wall?
This sux as i have 1 x 15" in a wall and get moved to Modified 3-4 and could be up against someone with 4 x 15" in a wall and 8 amps and im running 1 sub and a max of 4 amps..

Scott, it says "walls permitted"

It says the vehicle has to be roadworthy nothing about the person having a licence!!
The thing i dont get is i have no back seats or seat belts in the back, This counts for the car beeing unroad worthy, But when having a wall u cant have them in!
Maybe im beeing picky but just thought id mention it!
Unless unroadworthy is just basic stuff..

Dunno if your serious or not... but if u are... CAAdB debut is at Glo AutoExpo next month.

in stock a, is removal of parcel shelf allowed for a hatchback?

ripped:
i see no rule saying that you can't remove it.

The rules look far from complete and quite a few things have to be defined so people who do not know much about SPL can understand the rules..

Things like what is a Cut-through?

What does "SPL increasing passenger compartment modifications are permitted." actually mean? examples?

How extreme can the undercarriage battery box be - how big, can cutting/welding be done..

What is an "average" sized adult?

An example of inhibiting the normal operation of the vehicle?

Are consumer removeable panels allowed to be taken out in stock class - ie parcel shelves that can just be lifted out..

What does the fire extinguisher rule actually mean.. Would the competition organizers having an extinguisher be considered to "have access" to one. So in 2004 you WON'T need your own one? (Requiring one in every car would be a really good rule if you don't want any competitors)

The 140dB rule, how about allowing it if adequate hearing protection is used and CAAdB is NOT responsible for any damage that is caused. Of course CAAdB can still strongly suggest that no one sits in the car above 140dB.

"Limited to 1 battery in factory location with minor modification." Minor modification to what? What is a minor modification?

Add the "tint is acceptable" to the modified class window modification rule

Also, a rule that states that non sealed (ie batteries that vent gasses) are not allowed inside the passenger compartment.

"Frequency bandwidth of between 20Hz to 80Hz." what does that mean? What if you played music, or square waves? etc

--------------

You really need to get some people who are farily new to car audio to have a look at the rules and see what they think..

And how about us guys who build our cars to SS 1-2 NW specifications? Does this mean we are going to be against guys with walls all of a sudden? Everyone will say just build a wall. I know this, but I dont think that is alot of cases this is very practical. I think there has to be some definition between people with walls and those without. Otherwise how can we possibly compete against people doing close to 160 with walls, when super street NW is around the 150 mark. We have to find another 10 db from somewhere? I think that we really need to look at this otherwise there is no use of myself for example turning up to a CAADB run event when I have no chance of winning. I may be wrong because the link just doesnt work for me and i cant get the rules, but I wont be happy if i have to compete against guys with walls. Like people that have L7s who have purchased 12 inch woofers and will be disallowed because they arent round.
So Mr_Bob you can see there is a BIG difference between CAADB and DB Drag Racing! Ones that need to be fixed ASAP for fairness to all competitors concerned who will be pushed up due to Angelo not being able to run comps and CAA running them. Lets try and keep it uniform, yet aleviate some of the problems encountered with db drag racing. If there is no SS 1-2 and SS 1-2 NW, then thats a bit unfair on those with boxes. Dont yew all agree?

window line is used in dB Drag etc so it is nothing new

Dave, you're in Super Street normally, why would you be changing anything? As you'd be in the middle class here?

Well I was hoping to build a No Wall install coz it's a bit too much enclosure for a semi-daily driver.

So I'll simply have to give it my best shot with a normal enclosure and hope for the best.

It's the rules, so it has to be accepted.

it's a very vaild point.

however how many times has SS1-2NW class been run?
i've been to a few comps (not half as many as alot of others though. including yourself)
and i'm yet to see that category run, it usually gets combined with SS1-2 anyway. then you've got the same disadvantage.

only 150 in SS1-2NW?
they're hitting higher than that in S1-2!!!

my point about modified a (our equivalent of SS1-2)
was that originally it didn't permit walls,
so anyone with 1 or 2 subs in a wall, in modified class were forced to run against the modifed b class (SS3-4 equivalent)
which is far more ridiculous.

modified class is there for people who are happy to have a less than practical setup, they will mostly be cars that are street legal, but maybe not daily drivers.
those who wanna build a car with 2 15" subs and make it loud can still compete in stock b, assuming they conform to the stock rules.

in this way CAAdB is fairer, because we won't end up combining SS1-2NW with SS1-2

the only downfall is that if your car is too modified to conform to with stock class, but doesn't have a wall, you've gotta compete against ppl with walls.

the major difference between stock b and modifed a
is the fact that you're allowed a wall.

more batteries and amplifiers too i guess.

[ February 15, 2003, 18:31: Message edited by: Mr_Bob ]

That's me to a T.

Bum - Wouldn't your car be Stock B legal?

naah - i've got no back seats at the moment - they were in stoage at the sound store where i got all my gear years ago and they chucked they out when they closed!

[/QUOTE]Dave, you're in Super Street normally, why would you be changing anything? As you'd be in the middle class here?[/QB][/QUOTE]

that means the mu has a wall. the SQ box in the mu is above the window line. 2 12's in a 2.4cu.ft = a wall tell me that's not gay

Na Dr Evil my car wouldnt be street B legal because of the following reasons:
1. My deck is held in my hand
2. I intend to run 2 batteries in the boot
3. I will be removing the back part of my rear seats for a bigger box this install.

This means i will be competing against the extreme car audio buzz box! Oh well no hope of me getting a first place unless they dont turn up!
Unless someone wants to change the rules in street B which would be a VERY good idea. That way street B would be very similar to SS 1-2 NW and Street 3-4 which are very similar now and then modified would allow for those in SS 1-2! Now there is an idea!

You guys wait until Revision 3 to bring most of these things that have been in place since Revision 1 up ???

Anyway, guys, this is being developed in conjunction with YOU, there is no limit to how many revisions are required.

INSTEAD of complaining though, how about posting your thoughts as SUGGESTIONS, clearly worded, and refer to the EXACT part of the rules you are referring to, and class also.

Also, I am on my way out, and will be reading all this in greater detail much later tonight, but bassaholic you seem to have completely misread the fire extinguisher guidelines. They are NOT compulsory in 2003, and will be in 2004. Not a big ask for $22 from Autobarn to protect yourself and your investment. We could have them available for cost price at events next year.

OK well my suggestions would be as follows:

Stock A should be run very smiliarly to street 1-2 in that the motor should be allowed to run. I think alternator doesnt really matter that much and square woofers have to be allowed as they are 12 inch woofers.

Stock B should be a culimnation of Street 3-4 and SS 1-2 NW in that yew should be able to have a maximum of 2 batteries in the rear and either 3-4 12 inch woofers or 2 15 inch woofers and a maximum of 4 amplifiers. I also think that the box should be able to go forward beyond the normal boot size so that us SS 1-2 NW people dont get pushed up into modified.

Modified A should be similar to SS 1-2 wall division.

Modified B should be similar to SS 3-4 once again allowing for walls.

Extreme division doesnt affect me a great deal so i will let others put their ideas forward.

I agree with extinguishers as i have already had one fire in my car which Lukas was kind enough to put out for me.

Anyway those are my ideas and I cant see anyone complaining other than those who will be against squares in stock A. However get a pair of say DD 9512s and I am sure the shoe would be on the other foot. Disqualifying squares from stock A wont have the desired effect, which is to make round speakers have more of a chance. Round speakers are definitely not dead

I disagree with the sizing rulings... for stock A that is... it doesn't "add" up as such, like andu pointed out and ben said before, a 12" square is still a 12" sub, something like a DD/bramha, etc, have a HUGE advantage over the squares, purely because of xmax, anyway, the other issue is the Hex subs (they come in 12" don't they?) and the focal 13" subs....... i don't know of anyone doing spl with them, lol, but, for future reference, maybe they might!

[edit - after reading through these suggestions, these rules are FOR the people, not for the PERSON, remember that.... ]

[ February 16, 2003, 00:16: Message edited by: ubugger ]

i stole this from the N.S.P.L. page

Beginner SPL


Beginner SPL is for first time competitors who do not work in the 12 volt industry of electronics as an installer, or salesperson.
The same rules for Unlimited SPL apply to Beginner SPL.
A beginner vehicle must retain the rear seat with the system installed behind it. There cannot be a wall in a Beginner vehicle and the speaker box must be 12 inches or more from the roof.
A Beginner Car vehicle may be a hatchback car (Ex: Honda CRX, Ford Probe).
A beginner Truck/SUV vehicle (Ex: Chevy Blazer, Ford Ranger, Ford Explorer).

One battery for all stock classes. 90% of the competitors will have only have one battery anyway, so the rules are good for the majority.

No point having 2 batteries in stock, or pretty much everyone will be in that category.

Gotta keep alot of people out of stock class, or it wil become to crowded.

[ February 16, 2003, 00:53: Message edited by: Maz ]

I think that after the GLO show, Fire extinuishers should be mandatory at all events. It is a really sound investment, and for 20-30 dollars it is worth every cent. I think that you don't appreciate the value of one, until you have to use it, like i did.
I would recommend the size of 0.9 kg. This is the most common type and the ones required for your cams license and the like.

Also with each revison is is possible to show any modifications or addiotions in italic or color. It would make things easier to read, maybe even a list at the start.

Its looking good.

Maz I agree that street 1-2 aka Stock A would become over crowded however combining Stock B and SS 1-2 NW would not have a great impact. At most comps there are only one or two street 3-4 AKA stock B competitors. So throwing them in with the SS 1-2 NW guys are not going to make it over crowded, it will just merely give the guys in the old street 3-4 a lil more competition, and give the guys in SS 1-2 NW a chance. Either that or we split wall and NW classes apart in that we have Modified A NW and Modified A Wall. That would work as well.

it's gay. but it's not above the window line, it's at the window line, so it's not a wall. just remount the amps somewhere else.

i think the rules are fair now.

I have now addressed this window line rule, and will be posting Revision 4 later tonight.

Hang about until you see the new revision.

i think the rules are fair now.[/quote]I still think it's a gay rule but rules are rules. Anyway I just measured up the ute and I can fit a 11cu.ft box and stay under the window line time for a new box
