Exclamation where to get or can i make it? "crossover"

i need to make a cossover for a subwoofer. basic design (built-in, basic PC board and cercuits) i need a crossover that cuts off at about 250-300hz and i need it to handle a maximum of 4,000watts. (wubwoofer is a 4ohm 4,000watt 15", box size: 4.0 Cuf/ two 4x11.25 ports) does anyone know where i can get one, or if they have a design and where i can get the parts from to build one on my own? looking for something no bigger then 0.075 Cuf displacment (6"x8" size of PC board)

4,000 watts is pretty high power for a passive crossover. You might look into an active crossover to be placed before the subwoofer amplifier. Where did you get a 4,000 watt driver? What amplifiers are you using?

when building my PA systems, i like to use car audio subwoofers, even tho i have lower inicialations, they are able to pump more then most PA woofers. i like to make my system small so the sub is a 4,000watt 15". and i have two amplifiers, both are 3,600watt brigdable each. system consists or will consist of two 12" 2way 2,200watt PAs and one 15" 4,000watt subwoofer. but i only use car audio subwoofers for the sub, the PAs use pro audio parts. and so your saying that its rather hard to put a built in crossover inside the sub? because iv seen som that were 5,000watt that had it that way...

Those 12Volt guys where you get your drivers should know how to build a crossover for you. I'm not saying you can't put a crossover in the sub, just if you really had a 4,000 watt requirement, that would be a lot of power, particularly for a small size. But since you have explained we are talking about car audio, it is somewhat explainable as they have different watts.
