competition classes

Ive put together a new setup with a blown 15" sub as a passive radiator. Am i right in assuming a passive radiator doesnt account for cone area the classes are based on. The setup is 4 8's with a 15" pr.

You are correct Tony, but I will have to verify that the 15 isn't hooked up and other stuff. I am sure that you understand.

how? Will i need to take it out for you?

I think that would be best, so others could see that it wasn't hooked up. I will have to get with a few other people that help write the rules and I will let you know.

ok, i can do that, theres not even a magnet on it either

Jeff you might want to look at re-wording the rules to make it clear about a PR if not already done so. The classes are based on cone inches which the PR definately has cone area, but it would be the same as a port in this situation. I have no problems with him running a 15 PR but someone in his class that gets beat may think other wise about it.

Just letting yall know, ill be bringing my new working 15 to the next comp. I had problems at that last one it batesville, so im goin to see what numbers it really puts up next time.
As for the PR setup, here is a vid of build and of it playing if you feel like watching:

That looks pretty good Tony. James thanks for heads up on adding the PR to the rule, I will have to do that. I want to know yall's opinion on changing classes. Should we stay the same, or also add amplifier limits to each class to help make things more compeitive. IE:

0-250 70 amps of fusing
251-500 150 amps of fusing
501-750 300 amps of fusing
751-up unlimited fusing.

What do you yall think.

Its tough for me to say if the rules should change. I only made the last comp last year. I plan to hit about every one you can do this year since i know your doing them now lol. IMO though I thought the classes seemed very fair. I personaly would not like that rule because that would bump me up a class when i already have a big disadvantage running in the big vehical i have. With the battery rules i dont see the need to add the fuse rating rule. Maybe though you could limit the number of amplifiers to be used in certain classes. If not done so already you might want to restrict how many alternators for all classes but unlimited.

Something like this.
0-200 (1 amp,1 alt max)
201-500 (2 amp, 1 alt max)
501-750 (4 amp, 2 alt max)
751-up (unlimited)

I dont see a problem with power being high because the classes are not based on that but rather cone area and with the battery rules in place they will limit power. The only exception to that in my book is say walled or other setups that are only SPL oriented instead of a street set up. They should move up to unlimited or maybe if there is enough we can get a more SPL/Demo class for true SPL vehicals. Im about to do a wall project. I myself would expect doing the unlimited class or a true SPL class for that build as i see these as street based comps. There are not many true SPL system left in AR. So makeing other than the classes set would probably not help now but something to think about in the future. I think most SPL or unlimited guys would be using this as testing on the TL or just to show off there ride rather than just to try and win a street based event.

I know i would love to see a bunch of true SPL rides doing there thing again. AR used to be a hot spot. Just keep doing what your doing Jeff. Im sure we can bring it back to life.

I would like to see somethin like just classes based on just in^2, or # of amps. Since my system is a single 15 and i have one amp i would be able to run in a competative class. I think the fuse rating way is mostly covered by the batteries. but it would be a better way to regulate things since it just says how many batteries and not how big each would be.
I have a question about the in^2 classes, is it based on actual area, like the Sd of the sub (127in^2 for a 15), or sub size area (15 dia = 177in^2)

As for the walled cars, if there is a rule for this made, will it regulate what is a wall, like behind b pillar and under window line is not concidered a wall.
I am goin to try and have a dual 15 setup for comps somethin this year. and it will not all fit in my trunk. So am havin the box come out to the backseats too. Ill wait for rules before I build though.

I had another idea for another thing to do at the comps. It might take up more time though. But i was thinkin about somethin like "Lowest Hitting Car"

Fritosaregood the square inches is based off the sub woofer not the Sd.

Many other sanction bodies say if it is in the back seat it is considered a wall and/or if it is above the glass. Most for street classes use the ruling of it must be in the cargo area. Although most of the time this is still up to the judges to decide if it should be bumped up or not. Usaci has to be the greatest at this double standard lol. for say a extended S10 you can remove the little rear seats and use the whole space all the way up to the rear window and all the way up to the b-pillar. In a full size truck with say a bench seat in the rear the box has to remain under the back seat which really limits space and has more area to have to pressure. I never understood that rule lol. As for cars the rules for stock classes the subs must remain in the trunk which against a small hatch civic is really unfair. Anything foward of the rear seat is considered a modded vehical. Hopefully Jeff or someone has a better idea than that which will keep the classes a little more fair and competative than that would.

Just an FYI, we looked at the results for all of last year's shows and by adding the fuse limits, it would have made the lower classes much more competitive and the difference in scores really narrowed. The top class still had a bit of separation, but there wasn't as much participation in that class.

Like i had said i only made the last comp. So as for the whole season i dont have much idea as to what kinda numbers got posted. I know i would dislike it because im fused at 200amps for my 2 amps for my subs bumping me up when i already have a disadvantage running a big SUV in the 251-500 class. Personally if it got changed i would just run a 75amp fuse per amp and just burp it giving me the same number and getting around the rule. I guess what my point is. Is that if you want to limit by power do power classes not square inch classes. I can understand why you want to close the gap by limiting power but just as in any sanction people are going to work around the rules to give them a competative edge. I didnt see a problem with the way the classes where. I know back in the day if i got beat by say .1 Db i would be pissed. If i got stomped it was well, time to re-think my set up and get stronger for the next one. Im not trying to complain by any means by this. Just stating my opinion. I think as the competetors keep coming, growing in number and become more aware of how to get bigger numbers with design you will continue to see the numbers gap decrease.

how will the fuse classes be set?

As far as I know, he still hasn't finalized the rules and is still taking input. We talked about the fuse rating system as a way to keep the bigger, SPL systems with large fuses or no fuses at all out of the smaller classes which we wanted to keep focused on the more daily driver/street beater type systems. Any suggestions are greatly appreciated.
