I was wondering about the connection point that the conductors will be counted. If someone runs multiple coils/subs and runs a conductor per coil to a connection point outside the box but only run a single conductor to the connection point from the amp is this legal?

I know that right now i have a conductor per coil to a block mounted to the back of the box next to the amp. I have a single set of short conductors going to the block. Do I have to make all the connections in the box or can I run what I currently use? [Confused]

Actually, I have a similar question in which one response may be able to answer both.

I am wondering how the electrical conductors will be counted also. In other words, will the conductors be counted as the number of outputs actually being used from the amps, or will they be counted as the number of conductors actually connected to the coil.

Example 1: A person has a single coil sub and he/she connects 4 amps in parallel to the coil. Does this count as 8 electrical conductors? I assume it does, just wanting to make sure.

Example 2: A person has a single coil sub and he/she connects 4 amps in series to the coil. Does this count as 2 electrical conductors or would it count as 8 electrical conductors as all 8 outputs are required to be connected in the circuit.

I think you all might see where I am going with this. i see it as a possible loop hole, if a competitor can get it to work.

Maybe the rules state: Only 2 electrical conductors may be used to complete the circuit of a coil. I am not sure if this is worded properly, but I am sure wayne could clean this up. The only glitch I see here is that strappable amps wouldn't totally dominate in SS and above.

Just a thought,

Jason Meyer

I don't see that being a problem do to I don't remember seeing anything in the rules in ss or ex about conductors and street/street max have limits on amps

5-4 The program material must be reproduced using conventional loudspeakers (subwoofers). The determination as to whether a loudspeaker is acceptable for use in dB Drag Racing competition shall be at the sole discretion of the dBDRA.



Additional Guidelines:



· The dBDRA defines a conventional loudspeaker as a sound reproducing electro-mechanical transducer that incorporates a cone, surround, basket, and voice-coil.

· The loudspeaker must be powered directly by the audio amplifier(s).

· Loudspeakers incorporating servo mechanisms, actuators, or any other form of mechanically powered motor are specifically prohibited.

· A maximum of 4 electrical conductors may be connected to each woofer.

· Compressed air, explosive devices, etc. are expressly forbidden.


This refers to the number of conductors coming from the amp. I don't care if you parallel coils, series coils, etc.

Ok then from what i am seeing the conductors will be counted at the output of the amps and i can then have a distrobution block with six conductors,3 dvc speakers,and still be legal using a single mono amplifier.

In section 15. it reads:

A conductor is a single wire (solid or stranded) that is used to carry electrical current. A traditional speaker wire consists of two conductors (one positive and one negative).

Suppose that someone wants to use some "non-traditionnal" conductors. They connect 4 amps to a quad coil woofer, use 4 "+" wires from the amp to the coils and each "-" are hooked with metal plates (Not solid wire) from the speaker leads to the "-" of the amp. I think that if someone wants to stretch the rules to their full extent, he will say that "The electrical conductor that i'm using is not considered as a conductor in the Section 15 of the rulebook.

So in order to save some loopoles, i think that conductors sould be described in this way:

A conductor is a single conductive element (either metallic plates, wires - solid or stranded) that is used to carry electrical current. A traditional speaker wire consists of two conductors (one positive and one negative).

Or something like that, just to replace wire to something else, just to prevent people of using other material as a conductor and thus circumvent the rules.

(BTW, it's not about trying to cheat, it's to help make this rulebook even a better one.)

Wayne,

Does this mean that regardless of how you wire your amps to the coil, each amp will be counted as having at least 2 electrical conductors being connected to the coil.

Your last reply didn't exactly address that. Please let me know.

Thank you,

Jason Meyer
