ok guys heres the deal...i want to put a single pioneer 12 but i not sure if to use the dual 4 or the dual 2..can anyone tell me whats the difference...i am using half of a power acoustic 1600w gothic amp.....and the other 2 ch for the mids...{not sure of what speakers for mids yet}...my issue here is if the d4 will work and perform just as well as the d2...

the coil config is just to match your amp ohm config.

the 2 channels should bridge down to 2 ohms, so get the D4, wire it in parallel to get a 2 ohm load.

*edit*

as edhardy shows below, it bridges at 4 ohms, so you should get the D2

From what i gather the power acoustic is a four channel amplifier which should be bridgeable at a four ohm load. The dual two subwoofer would be able to be wired in series to a four ohm load to maximize the full potential of the amplifier without running it at a lower than recommended load which can cause warranty issues and may damage your amplifier.
So in short use the Dual two subwoofer.

but isn't the amp supposed to produce more power at a low ohm?
