buying this amp here
http://www.cadenceso...cts/F400-4.html

it does
"4 Ohm Bridged RMS Power: 250 Watts x 2"

I will be connect 2 channels to the fronts, and the other two channels bridge to a subwoofer.

can i confirm that i should buy a Dual 2 ohm Subwoofer and run both voice coils in series to get 4 ohm, then connect that to the amplifier?

i know the manual says 4ohm but I just wanted to confirm because i got confused as when bridging the amp sees half the impedance the driver. so when it says 4ohm does it mean the impedance of the driver or the actual impedance that the amp sees

Dual 2 Ohm is correct.

Each channel of the amp 'sees' a 2ohm load when run in bridged mode with a 4ohm driver.

If your amp was 1ohm stable on each channel you would find that it could run 2ohm bridged, and so on and so forth.
