hey guys....im getting ready to finially start competing again..better watch yourselves.    anyways down to business.   I am going to be running (3) 10 inch JL Audio 10w6V2's        now im amtrying to figure the best way to go

all 3 subs in series with the coils in series is a .66ohm load           (3) 2 ohm=.66 ohm

all in parallel   are 2 ohm load or a 8 ohm load 

or (3)  8 ohm coils in series are a 2.66ohm load

I have the following amps to choosh from     a kicker zr360, a Rockford 800a2, or a orion hcca250g4....

the orion would support the .66 ohm load,   and the kicker would support a 2.66 ohm load,   the fosgate would handle a 4 ohm load     all these amps are close output capabilities

orion is 800x1 at .5 ohm   fosgate is 800x1 at 4 ohm, kicker is 800x1 at 1ohm

any suggestions for sub wiring and amp configurations

Do this as it is the safest for the amplifier and most power efficient:

There are only one or two amps on the market today that will handle this impedance satisfactorily so chances are, this is not a feasible configuration for your system.

I would have to agree with Jeff on that.

Jeff,

      First off, you are confused on what exactly series and parallel wiring configrations are.   A parallel connection is where each coil is wired directly to the next (+ on coil 1 to + on coil 2, - on coil 1 to - on coil 2...  Series would be where you wire - on coil 1 to + on coil 2, and + on coil 1 to amp and - on coil 2 to amp.)  Bearing this in mind, if all coils (Each on a W6v2 is a 4 ohm coil) were wired in parallel to one another and to each other speaker, you would be presented with a total theoretical .66 ohm load.  If all coils on all speaker were wired in series to one another, you would be presented with a 24 Ohm load.  If each coil was wired in series with the other on each woofer, and then wired in parallel inbetween each woofer, you would be presented with a theoretical 2.66 Ohm load.  Also, the Kicker ZR360 will only put out 400w with a 2 Ohm mono load...  1 Ohm mono would make it run very unstable, so I personally wouldn't recommend it (and I'm sure kicker wouldn't either), the orion HCCA 250g4 puts out 800w at a 1 ohm load.  Your right on the money about the fosgate.  Personally, I would recommend you go with the fosgate amp, if it is one of your only options.  Time and time again I have seen them publish that they guarantee there amps will support a 2.66 ohm load (Several pitches of trying to sell 3 8 Ohm punch woofers loaded in a prefab box, especially in Crutchfield.)  Use the series/parallel wiring configuration I talked about.  Keep in mind that every year RF amps are getting cheaper and cheaper, and also since you plan on competing, you still have 400 watts more you can throw at them.  Hell, you can even feed 500w RMS to each of these, no sweat, so if you wanna push that meter even more, you could push 700 watts more to them.  Keep your options open, and if all your trying to do is push a meter, throw them in a well designed ported box.  You will get  a theoretical 3db increase, which would be the equivelent of doubling the amount of power you are giving them.  If you or anyone else needs any more help, feel free to e-mail me.
