I have to do a temp wiring contraption until I can get another amp, so hear is what I am up against

4-10's that have dual 4 ohm voice coils

2-15's that have single 4 ohm voice coils

what is the best way to wire these all to get the closest to a 2 ohm load ?

using the calculators I came up with this.......

wire 2 each of the 10's(4 voice coils) in parallel to get a 1 ohm load (4-4-4-4=1) 

and then run to 1 each of the 15's (single 4ohm) in a series connection with the above 1 ohm and get a 5 ohm load

so if that is half of the speakers, then if I run in parallel with the other half (5-5=2.5), my amp is 1 channel and stable at 2ohm, so I should get about 900 total watts at the 2.5ohm load.

assuming I have calculated the above correctly,

so there are 3 questions:

did I calculate correct?

can I wire it this way?

how much power will each speaker get assuming 900 total output? (each 10 would be running at 2 ohms and each 15 would be at 4ohms, would they all get 150 watts (900/6=150))

thank you for your help

The power distribution would be (in ohms) 2, 2, 2, 2, 4, 4.........with each of the 4 ohm impedances getting half the power of any 2 ohm.  So divide the total power up into five equal parts with each 2 ohm load getting one part and the two 4 ohm loads sharing one part.

If the power is 900 watts, each ten gets 180 and each 15 gets 90.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

is there anything out there that I can use to adjust the impedance level, say I have 2.5 ohm but I want it to see just 2.

Nope.

ok, thanks,,,,,so my first posts' assumtion and calculations were correct? and it is "ok" to wire that way?

Calculations above would be if all woofers were paralleled.
Per Each leg (the 2 x 10s and the 1 x 15) the 15 will get 80% of the power and each 10 will get 10%

Now I am really confused, if I parallel all woofers I would have a 0.4 ohm load, never seen an amp that can handle that

my plan was to parallel each 10" sub's voice coils (each one has 2-4ohm coils) giving each sub a 2 ohm load, wire 2 of these in parallel and get a 1ohm load, then wire it in series to 1 of the 15's and get a 5ohm load, do this for the other side also so I have 2 each 5ohm loads, wire those in parallel to the amp, and get a final 2.5ohm load to the amp.

does that make sense

that will work for now

I will get 360 watts to each 15"

and 45 watts to each 10"
