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

No, you cannot. You can only bridge 2 chips (or 1 4780 - bridge the 2 amps in it). The reason is because bridging means that the positive of two amps drive half of a speaker.
What you can do is parallel 2 sets of 5 amps then bridge them. That would give you amazingly low impedence drive.

peranders said:Seriously, it's easier to design an amp for max 10 KHz or a bit less than that and use MOSFET's. Driving MOSFET's up to 100-200 Hz requires almost nothing in power, nor in complexity.
Hmm, think I might try that.
Any good, simple, yet good sounding designs you have in mind using easily obtainable parts?
