Woofer is more suited for sealed applications.

Calculator shows a box size of 3.336 ft3 with a Qtc of 1.2, this per woofer so the total enclosure size of 6.67 ft3.

RMS power handling of the woofer is no more than 400 watts RMS per woofer.

With the dual 4 ohm coils of these subs an amp with an output of around 800 watts RMS at 4 ohms or 1ohm depending on how you wire the coils.

Reccomended amp-

thanx for the help buddy. What would you reccomend, to run at 1ohm or 4 ohm.

Also is there a diff in power between the two

With the amp i suggested run all coils parralel for a 1ohm load.

As for the question-(short non technical version)

At 4 ohms that amp will put out 500 watts RMS

at 1ohm it will put out 900 watts RMS.
