Street A Class - A maximum of 1 subwoofer amplifier may be used
Street B Class - A maximum of 1 subwoofer amplifiers (or 2 externally bridged monoblock amplifiers) may be used.
......
Question - What is a "monoblock" amplifier?
Answer - The dBDRA classifies monoblock amplifiers as amplifiers that are mono in nature, have a single input, have a single output (2 conductors), and that have the capability to be bridged with another monoblock amplifier. (One monoblock amplifier will drive the positive conductor to the loudspeaker load and the complimentary monoblock amplifier will drive the negative conductor to the loudspeaker load.)
So, how dtbrown says, up to now it is only allowed in Street A to have such a amp, because its not possible to bridge 2 of these kind of amps for Street B.
Is it a big deal to change the words: 1 subwoofer amplifier to 1 monoblock amplifier in Street A? ...and why doesn´t judges say anything about this issue?????????

you'd think that we'd get an official on here to validate the rule on this..
the amplifier falls within the RULES as stated for Street A. Anyone that can read will confirm that..you can argue all you want about it's intent and all that other stuff but the fact still remains it's within the rules of
-1 Physical amplifier for Street A..thats all..
so why is it that we can't get an official ruling on this?
This post was started 12 DAYS ago and yet we still have to hear anything from an official and FINAL CLARIFICATION on this.

its hard to say, while it is obviously 2 boards, it is marketed as 10,000x1. Also, it is not anyones place to disassemble an amp to count the boards, also voids the warranty.

I am officially stating that this amp may or may not be legal or illegal in Street A. It officially counts as 1 amp but may also be 2. Or 2 channels, but in one heatsink, which makes it 1.

What do you expect???? 1 amp against 2..... and you also would gain efficiency!
...and now imagine what you could do with 2 x 10kw Amps on a 650cu batt -> 90% efficiency or more....
Who is judging @ the moment the events, and how?????

REALLY GOOD POINT!!!!!!!!!!!!! if these amps will be allowed, than why the rules-changes? then they should have left the rules like they was last year, for all street classes!!! if these amps are allowed, they can still play on 2amps (but it will be 1 physical amp), this is NOT right, and you all know it!!!

The batteries that you can use in Street A severly limit how much power you can get out of an amp. So with 2 amps, or one huge amp, your current demand may be almost double what they are with 1 amp, or 1 amp half the size. Voltage would drop significantly and you will never see the full power from the big amp. So a smaller amp would have less of a voltage drop and can possibly make more power because it is running more efficient with the slightly higher voltage.
The XXV Goliath is a very efficient amp, It is more capable of making full power on a Street A battery than the Maxximus is. If the Maxximus go into protect because of under voltage, then I would be surprised if it will be even 2 tenths louder. And 2 tenths is not worth all the extra money and size to most people. Infact, in some cars, 2 tenths can be made up by not having the larger amp disrupt the airflow in the vehicle.
To me this is not just theory, I have tested tested.

There are a lot of other small amps that can't be bridged or slaved to a 2nd of the same amp. Does this also mean that 2 channel amps are illegal ? What about a class A/B...now you can't use those as well.
I don't see why there is a issue with this.The maxxmius IS 1 amp. All I seen is some one crying about haveing to buy 1 big amp...but the cost isn't much more than 2 large mono blocks. There are a lot of other amps that currently useing a simelar design.
To me it seems that there other amps out there that people should be worried about. What about the Kicker War Hourse, Earth Quake PHD20,000 and so on. If people are getting down on the rules for a amp designed to cervenemt the rules what about the stetsom 7k 12V. To me it would seem as though that amp was made to get around the 12 volt battery issue in street. Just makeing a point.
Any one that thinks they can run a maximus in street A given the battery size and no multy cells should try and use the maxximus and see how it realy works. Whats the voltage drop going to do to the amp.....why would you complain because some one wants to use a 18 volt stable amp off what....9 volts ?

You get the most Power out of a batt, lets say @ 9,5V! 1 amp on 0,1xx OHM and rise to 1 OHM, Batt= 10,3V, eff = 60% ====== 4000Watt 2 amps on 0,5 OHM (one amp) and rise to 2 OHM, Batt = 9,5V, eff = 70% ====== 5000Watt
That are Worlds, in STREET A!!!!!!
protect: @ such a comp level the amp goes into protect, when you say he should go into protect!

we are going on 3 pages and still no Official answer on this. how are the competitors supposed to start their builds when they dont even know if they're allowed to run the equipment?
how much longer do the people have to wait till an answer is given. this isn't some small item here, so it's not like someone can go buy it and then all of a sudden not have a problem using it if told so.

a 50kW amp in St-A? it'd probably catch fire before the wire would

I dont see any amps larger than the Maxximus working at all in Street A so why would anyone have 10 strapped amp boards in one case, there is just no point. The main reason why amps like this are made in the first place is just so the amp isnt extremely long. Power is so limited in Street A that going bigger and more expensive is so unnecessary. So if people are worried that letting this amp and others like it be legal, is going to set a precedent for larger amps, they shouldnt be.

Would be the similar to running 2 Goliath's strapped. Maxximus could be used in Street A as long as conductor rule is not infringed.
Andy From Boomin Audio Competitions said you can use Maxximus in Street A-Providing conductor rule is not infringed...

wayne ahs always said , 1 heatsink, 1 amp. dbdrag counts PHYSCIAL amplifiers.
the maxximus is ONE physical amp.
you can run it without violating any other rules (such as conductor)
wayne has said it. the rules state it. and there, you have now had a 4x judge say it.
