that really made me laugh for some reason, i think because i never had a vehicle that could be tuned very high, so i am used to it

first generation crx peaked at 50hz
full size bronco peaked at 52hz

SS1-2 Lancia Y10 frontdoor's are moving like 2" when you push +160dB at 74Hz.

Why HU must to be IN the car when competitor have to be OUTSIDE the car?? CD-changer is must, not an option. What choises you have for street HU. Alpine.. Hmm... Alpine ... Hmm.. Alpine... I would love to use pioneer BUT there is no remotecontrols available in the europe that could be used in a dBdrag.
Allso you must modifield your remotecontrol if you like to use it with new cars like Renault. These cars have polarized windows and RC wont take contact trought the class (beam wont penetrate window).

Please Wayne do something about this HU rule.

Here is what you do. There are several head units that won't skip there. Try a panasonic or clarion. As far as remotes not working buy an IR Repeater. Lots of people over here use them, I suggest trying it. The reason people can't be in the car is because of hearing damage. It would be silly to sit in a car for 4 burps every show you went to. If you're car can't handle being that loud, maybe you should get something else.

S class will soon be doing 160 dB on new meter!!! if not in this year than in another!

It is nothing like streetbeater if someone must operate HU outside car.

Why are we making S class competitors life more dificult if they need to buy special CD changers, IR repititors, special HU-s that have decent remote that can be used for competitions....

Cheapest cables and plain HU outside car can do all that for couple of $.

With HU inside car it is even bigger difference among medium and top competitors!

And who will stop pro/top competitors building cars for ''amateurs'' ???

Leave S class at it is, maybe add 1x12'' class and focus on MS classes!

Why do we need to change and maybe kill THE most succesfull class?

This rule is so stupid. I listen to lots of music that is over 50 htz. Maybe 60 htz would be ok. And I'm not saying this for my benefit cause my note at finals was 49-50.
50htz rule is completely IGNORANT and would keep me out of dbdrag

For the most part of the 20 or 30systems i have instaled over the past few years only one of them was crossed over lower than 80hz....mine...and only a hand full wanted their systems for a 50hz+ peak.....as it stands the 80hz limit is fine....

That is the idea to stick with....i helped put together a ss 3-4 van (no wall) that does 159db (old mics) at 54hz and the pioneer in the dash does the job without a hitch......even with a 33hz test tone (make for alittle fun at comps)

80 Hz is an ANSI standard. Using the widely known committee's standard, as a basis for implementing a rule, is the logical and practical thing to do. To alter a rule regarding frerquency cuttoff limits, based on personal opinion, is an injustice.

hahaha that would definitely bring more people to dBDrag [Roll Eyes] (or not)


What will firsttimer said:

a - I burned my sub and 1/2 of amp and I will never again go to that stupid competition.

b - I burned my sub and 1/2 of amp and I will gladly do it again.

actually people like smoke, when someone opens a door and a whole bunch of smoke pops out, its a crowd pleaser. that would only increase crowds at dbdrag events. if the big boys start blowing stuff up, and can't replace it at shows, and start taking 2nd and 3rd places, they will learn to moderate their power

blowing their stuff up gives them a nice story to tell for their first time out. that story will be fresh in their mind and create a bond with dbdrag/ competing... some people will disagree with that, but guess what ITS TRUE!!!

Yep. I agree 100%. When I fried my amps and had a **** load of smoke coming out of my trunk I had about 40 people run over to my car to check it out.

In Finland, buying decent HU is easy as buying Fiat Panda in NY [Frown]

I bought my pioneer HU what i use on my everydayride from Germany cause it cost there only 40% what it cost in Finland and the choise in better. Local "car audio dealer" have like 4 cheap basemodel HU in stock.
Nice to try buy something if you cant have it nomatter how much you are willing to pay [Mad]

Sorry, this is OT but I feel needs to be said.

If a first timer has a street beater, scrounges up the money for a semi-decent setup then smokes it at a comp, they're not coming back.
When I was a kid if I entered my car in a comp and toasted the equipment that was the end of it. The equipment went in the bin and I couldn't *afford* to replace or repair it. I had to save for 4 months to buy a garbage 10" sub and even worse amp just to get some sound.
Who wants to keep replacing their gear at their cost ?
How is that going to attract new blood ? If anything it'll keep people away because they can't afford the keep repairing/replacing damaged gear.

Its not good for in the industry either.. a kids amp smokes and its a "real crowd pleaser".. and how does that reflect on the manufacturer ? People will tend to look at the competitor with the smoked gear and the guy next to him with unsmoked gear and "Oh well, Brand X must be pretty crap, look at how it blew up so easily. Brand Y in the other car is still working, so it must be better than Brand X". Manufacturers don't want that 'cos its bad for the industry.

As for this 50hz cap.. seems to me its just another "Lets try and ban Panda's, again, and disguise it as a rule change" tactic. Kinda like the 2 weeks before Finals where people tried to get the Crown A6000GTi banned by any means possible..

IMO Enduro is a stupid idea and would discourage people from competing.
I don't mind a 50Hz cap because a) I cross my subs at 50 Hz anyway when daily driving and b) it would level the field for larger vehicles.

no it would discourage people from running 6000w per sub in street class.

NO WAY!

I will know exact ammount of power from my monster amp to feed my monster sub.

Only subs that will blow will be cheap subs from newcomer that don't know anything about dB Drag, and will never try to learn hard way again.

OK, I am not competitor, but I am speaking in name of our competitors. They all started with small subs, and many of them ended with high quality goods bought for dB Drag competitions.

dr. loudness, enduro is a 30 second spl run, i don't think there are many 12's or 15s that can handle a street situation 30 second run with 6000w per sub. we aren't talking a 3 second burp...

I am in car audio for long time, I orgnize competitions here for 7 years, I have been on may European competions either as competitor, help to competitor, spectator, event organizer...

I have seeen and helped people starting from nothing to almost world / european championsip level.

And I am sure that beginner with bad box can fry CHEAP sub and amp with 300 W and that someone with good experience can put 4000 RMS to monster sub without any damage.

I am not in the mood to find exact numbers, but Finish S-A champin is doing over 150 without engine for deathmatch.

How can you compare that number to first-timers?

I am 100% sure that 50 Hz limit or enduro will make even bigger diference between experienced competitors and newcomers!

can someone start talking about real numbers?

For instance:

if we will have 50 Hz rule competiton will be more interesting because... and we will have XY % new competitors because...

If we will have 50 Hz Rule new competitors will win because....and we will have XY% of new competitors...

if we will have enduro for S new competitors will win because...

I dont see how will any of suggested change attract more competitors. Same people and same companies will still be winners in S classes

Lets build better MS class for real beginers!!!

I don't like the idea of Enduro classes. But one thing is for sure, if they were made to play for 30 seconds at a time it would take the "big Amp" factor out of the street class. You just can't put that kind of power to a subwoofer for an extended duration so the power levels would have to be kept moderate. You would see a huge decrease in SPL levels, lots of blown equipment, and an exodus from that class.

That is the only thing that will work....call street class "pro street" because it is and just call the new im proved mini street just plain "street".....i know of at least two or three guys at every comp i went to that did not want to enter "mini street" but entered street class and got their heads handed to them...doing this since the old mini does not go to finals will keep the pros out of it.....simple as that.....

For the 1st time ever... I agree with Jared when he voices his opinion about street... [Eek!]

But I've done enduro events... in San Diego... It was Joey Sprague, Peter Noel, and myself.... I ran two Beyond Audio 12's from two SH-1... for two minutes... Subs didn't blow... amps didn't fry... (my cab did smell a bit though [Big Grin] )


the only damage done...
 -

If the frequency is lowered... I don't care...
If the score is an average of a 30 second run... I don't care...
dBDRA makes the rules... I'll just build it and pay my $30.00 and do my best... period...

Peter Pejovic

sake of arguement street A has 1 72Ah battery(sp1700), has 6000w (prolly has more in your case but lets just say 6000w) we will have that 6000w draw 700 amps that equates to complete drain in 6 minutes or so. so cca vs voltage, would have your voltage be around 8-9V at the end of the run if that? i am just trying to understand some of these comments...
