i am running 4 12 inch single voice coil (4 ohm) sub woofers in a sealed box on a 2 channel amplifier the amp is 2 ohm stable do anyone know of a way to wire the woofers at 2 ohm load and not 4 ohm or a way to get the most power out of my amp the amp is a interfire 2950c it is a 1000 watts 550 watts rms help please

Sure. That amp is stable at 2 ohms per channel, and stable at 4 ohms with a bridged load. Wire your four subs so that you come to a final 4 ohm impedance and bridge across the channels. The amp will output its most power into a 4 ohm bridged load, which is 550 watts RMS / 1000 watts peak.

Wire two of the subs in series, and the other two in series. Then connect the pairs in parallel for 4 ohms.

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

The diagram above WILL give you 2 ohms - PER CHANNEL (if bridged).

If your amp is not bridgeable, then use this diagram...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
