My current setup consists of 2 Dual 4 ohm subs at 400 rms a piece wired series parallel at a 4 ohm load. I am wondering if it is possible to wire a third Single 4 ohm in parallel with the other 2 to present a 1 ohm load overall. In my mind it seems to work out. If so what would the power distribution be of such configuration.

The SVC sub would receive half the amplifier power, the two DVC subs would split the other half. So the SVC sub would receive 2X the power of either of the DVC subs, and be louder (how much louder depends on the relative sensitivities.) And the net load on the amplifier will be 2-ohms, not 1.

Thanks for the response. Would you care to elaborate as to why the net load would be 1 ohm. Wouldn't I be paralleling 2 4 ohm loads down to 1.

Nevermind I found my mix up. I was confusing with paralleling down 2 DVC 4 ohm subs down to 1 ohm rather than thinking of them as 2 SVC 4 ohm loads.
