From the second draft rules:

"Amplifiers that are constructed in such a way as to circumvent the amp
quantity limitation may be prohibited from use in this division or may
count as multiple amplifiers. Please visit
http://www.termpro.com/dbdrag/rules/rules1.html for more information."

How is this defined? Multiple power connectors? Multiple boards? Multiple heat sinks?

Are these amps legal:
US Amps USA-6000
SPL Dynamics EXT4000D
Trutechnology SH-1
Audiobahn A5000SPL

And if they aren't legal, would they be if they were re-designed to be all on one PCB board and one speaker terminal?

I also am wondering but i would guess ure right if it is all on one board it will be legal.

What is the problem we are trying to solve here? Street cars having way too much power, power is too expensive for "the street people". I agree, we do have a problem.

But this is not the way to solve it. Lets assume that we ban multiple board amplifiers. After that JBL/Crown 6000 will be the most powerful amplifier, there is also the soundstream 5000w. I'm sure there will be other new amplifiers soon to fit the rules.

Will the power / cost issue be solved? No... This will just be extra money and time spent for manufacturers building new models to fit the rules. Who is going to pay for this, the consumer - "the street kid".

It makes a lot of sense to use existing parts to make new amplifiers, why make a new board and heatsink just for dB Drag?

This is the only thing I can think of to limit the cost and power:
Street A:
1 amp, 2 conductors, amp must be strappable.
Street B:
2 amps, 4 conductors, amps must be strappable. (or 1 non strappable amp)
Street C:
4 amps, 8 conductors, amps must be strappable. (or 2 non strappable amps)

This will keep SPL Dynamics EXT4000D and JBL/Crown 6000 out of street A. You would still be able to use SPL Dynamics EXT2000D, the new Rockford 3000, and similar amps. It will effectively cut the used power in half.

PS. Many thanks to the people working on the rules, it must be very hard to make the rules fair for everyone. Just a couple more adjustments and we are done [Smile]

this is a great first step.

thanks for posting a list of amps

IMO, amps like Zapco 4kw, JBL 6000 Crown and RF3000t should not be allowed in the street classes because of both price and power.

There is not a perfect way of doing this, I hope Wayne can do something fair for everyone.

And what about amps that were just never strappable like the Earthquake D2 and D3, the Zapco 9.0, the Memphis Mojo, and many others that have been used for years and would now be illegal under this new system. I am not trying to shoot your idea down either, just trying to point out a possible flaw.

In the case of a 4kw, it has 4 conductors so with the new rules I see no advantage in having a 4kw over 2 9.0's. I feel a 9.0 is a vary streetable amp.

Yes, and you would be able to use it in street A.

However JBL/Crown 6000, US Amps USA 6000, EQ D3 and other similar amps would be out of street A. These amps would be legal in street B and C

This is true, these older amps would be out of street A, but legal in B and C. But they would be underpowered compared to largest amps like JBL/Crown 6000 or a pair of RF 3000's.

Do I remember correctly that the new mojo is strappable? You could use that.

So you mean to tell me that you would be able to run a 3000 watt RF but you couldn't run a 2000 watt Zapco,1000 watt Mojo, or a D2 2000 watt in that class with that rule? That just doesn't make good sense...

Well, true. But this makes more sense than current rules (2nd draft), you can use a JBL/Crown 6000 in street A, but not US Amps USA 6000 or SPL Dynamics EXT4000D. Does that make sense?

We are getting a little of the point here, the main issue is that amplifiers should not limited out of the competition just because they are build a certain way. We should try to limit power and cost. But it seems to be impossible task...

You guys just don't get it do you? A JBL/Crown will not work in a street car, a USA-6000 will not work in a street car. Wayne wants to properly count amps that were built specifically to circumvent db drag's rule on number of amps.

These amps include, but are not limited to:
Zapco 4kw(considered 2 amps)
SPL Dynamics EXT-4000D(2 amps)

Whether an amp is strappable or not DOESN'T MATTER!

Making the amp requirement for Street A, having to be strappable serves what purpose? You will only limit the amps that can be used by the "new guys" that everyone seems to be concerned with. There is no one solution to this "keeping pros outta street" dilema. But with what Wayne has come up with looks to be good.

Sorry but if I "have" to have a strapable amp just to be in street A then forget it. I'll take my toys elsewhere along with my comp team and $$.

No, I do understand that. Its been proven that a JBL/CROWN needs more juice then street A can provide. I feel no worries over a street a or even a street b car with JBL/Crowns. I was just pointing out the short comings of his proposal

The proposed rule is aimed at amplifiers which are obviously two whole amplifiers dumped into one heat sink. Such as those mentioned and the US Amps US6000. Those are obviously two whole amplifiers stuffed together. They have two set's of power wires, grounds, remote turn ons, RCAs, and all other terminals. Everyone knows that it is a pair of 3000s in one larger heat sink. Those amplifiers should count as two amplifiers because that is what they are. They don't need to be in the street class. This won't effect what the consumers are paying for amplifiers that want to compete in the street class because no one is actually buying these amplifiers at a retail level.

cool, but this proposal affects more then just the "2 amps in one case"... From the sounds of things Wayne has already made a rule to circumvent the "2 amps in once case" problem. He will just ban the offending amps.

Ok, this is getting out of hands, we should not argue what amplifiers are allowed and what are not.

The issue is that there is too much power available in street classes. Is the new rule going to solve it? No, there will be big single chasis / board amplifies that will be allowed. I belive some of the "banned" amp manufacturers will rework their amps to fit the rules, just extra time and money wasted...

Again, you should not ban amps because they are build a certain way. We must try solve the issue with too much power, and that is very hard. I cannot think any simple way to do that.

As for JBL/Crown not working of one battery. It may be true with current models of the 6000. But if SPL Dynamics can make two 4000D's work of single battery, it find it hard to belive that JBL/Crown could not do the same. They just need to modify the protection circuitry to allow more voltage drop.

Ok, I take the strappable-issue back. The rules should not be changed in that part. I was just thinking about Finnish market, here strappable 2000W amps are easy to get and common in competitor circuits. I did not consider the whole picture. We should not ban old amps just because some new and more powerfull amps.

The best ruling would in my oppinion be the original:
Street A: 1 amp, 2 conductors.
Street B: 2 amps, 4 conductors.
Street C: 4 amps, 8 conductors.

No limits to how the amps are build because it is not going to solve the problem with too much power.

Since we have limitations on the number of amps that can be used in the Street and Street Max divisions, it is important that we accurately count the number of amps that are actually being used.

For example, if a manufacturer takes 2 amps and bolts them together, then the new "amp" should count as 2 amps. This doesn't ban the amp, it just insures that it counts for what it really is.

I have a pretty good idea of which amps need to be added to this list. Now, I would like to hear from you.

Thanks in advance.

To me that one looks like a 2 channel single board amp. Is it?

Sorry, I'm repeating myself, but if we rule like this we will leave door wide open for the JBL/Crown 6000. We will make people change their amps to more expensive, is that good for the sport?
