well i need at least 300-400 Watts

its the description of the woofer that i maybe ill use

Tempest combines a low Fs (18.6 Hz), medium Vas (317L), and medium Q (0.38) with an incredibly long throw (16.9mm one way) for a subwoofer driver capable of huge deep bass output. And with a 750W power rating, you can use all that displacement, too. We've run a LOT more power through this unit than what we've rated it for. Tempest should be able to take a beating!

will be great to use 4 IC in bridged mode
