My head hurts. One I those situations where the answer is there but I'm so overloaded I can't see it anymore frown.gif

I have four boxes that house two 4ohm dvc subs. I have a choice of wiring them for either 1ohm or 4ohm coming out of each as you can see here:



In the end there will be four of these boxes and I need to be at 4-8 Ohms for the combined resistance on the four boxes.

I hope I said that right.

Should I wire them as 1 ohm or 4 ohm to make the easiest final resistance?

That being asked could someone show/explain to me how to net a final resistance in my range?

Each box of two drivers will end with just one +- wire out. I need to then take the four wires and wire them for 4-8ohms.

Again, sorry for the wording. I'm flustered.

Jeff

I think what I'm seeing is if I duplicate the 4ohm choice as shown imagining the 4ohm outputs as wires from the boxes I can net 4ohms.

You have two decent choices, both giving you a final impedance of 4 ohms:

1) Wire each box as 1 ohm, and then wire all of the boxes in series.

2) Wire each box as 4 ohms, and then wire each pair of boxes in series, and the two pairs in parallel.

I would prefer the latter myself, as each box is 4 ohms if used stand-alone, but wiring the former is simpler.

If your amp is dual 2-ohm or mono 4-ohm bridgeable, then wire it that way.
Otherwise, wire it as dual 8-ohm.

Or, if the amp only does dual 4-ohm, you can connect just one coil from each, with the understanding that you'd want to get another amp, for quad 4-ohm operation.

Assuming your box is not limiting you in some way.

Mark choice 2 is the way to go. Took me a bit to filter this.

Thanks for the replies guys. Much appreciated.

Funny part is I hardly drank last night. Info overload haha
