ok stereo guys, i got one for you. I built a sealed box with a 4 om dual voice coil 12" subwoofer. I have a 2 channel amp that im going to bridge.But i have no clue on how to wire it for my application. I drew a diagram and included the specs for each componet. If some one could draw a way and different ways to wire this for optimum performance it would be great.

Your amp is only bridgeable into a 4-ohm load or higher. You say you have one DVC speaker, so your best option is to operate at 8-ohms.

You need to invest in a new amp...with an 8ohm load yur only going to have about 100w running to that sub, wich is way underpowring it. Try to find yourself a 2ohm stable amp that puts out about 700-900w @ 2ohms....I have a kenwood amp for sale that would be perfect for you...

You could just run the amp stereo.

If there is a problem with running subs this way someone please chime in. I have done this on several setups without a problem.

Im not possitive on that at all, I was just figuring that a left and right signal going to the same driver would conflict...
