Using Tri-Way Crossover
I have a Kenwood 629s 150 watt 2 channel amp that puts out 60x2 at 4 ohms or 150x1 bridged into 4 ohms. I wanted to know how many watts will be going into the front channels and how many watts will the subwoofer be getting if used with the Tri-Way crossover? I want to use this Tri-Way crossover:

The crossover has nothing to do with how much power is sent to the various speakers. It all depends on how much energy is contained within the specific frequency band. All the crossover does is tell the sound where to go. It doesn't have control over how powerful it is.
In general, the vast majority of the sound energy is devoted to the low frequencies. High frequencies require very little power.

O.K., let me re-phrase my question. How much power will my 2 channel 60x2 or 150x1 watt Kenwood amp put out to the front channels and the subwoofer when using the amp in Tri-Way mode? I basically want to know how many watts the amp will put out to the front speakers and also, to the subwoofer when used in a TRI-WAY application.. The specifications my amp came with say nothing about power ratings when used in a TRI-WAY application. Thanks

Did I accidentally type my last post in french? The crossover doesn't have a f**king thing to do with power output. The only thing that determines power output is the impedance presented to the amplifier circuit. The impedance is going to be different at all frequencies, and far more complex than anybody can reasonably determine without test equipment. I will tell you that using passive crossovers in a tri-mode setup is an extremely inefficient way to get things done and your total output is going to suffer compared to active powered crossovers.

Again, fill in the blanks; when connected to 2 channels my amp puts out 60 watts to each channel, when two channels are bridged the amp puts out 150 watts to one channel, When using the amp in a tri-way application the front 2 channels receive ___ watts each and the subwoofer receives____ watts. Thanks for your help.

Listen to me. The crossover doesn't just magically slice the power and distribute certain amounts to certain channels. There's no magic number here! It depends on a million things, including but not limited to, the components in the crossover, the crossover frequency, the impedance curve of all drivers involved, and how the amp is biased.
There is NO ANSWER to your question.

O.K., lets forget about the crossover, I think it's confusing you on answering my question. A two channel amplifier puts out power to two channels, when that same two channel amp is divided into 3 channels, how much power would each channel get (no crossover used). I just want an educated guess like 50 watts for the front two and about 100 watts for the sub. I understand the amp puts out more or less power from different impedances but, I stated above 4 ohm impedance. If there's no way of telling how much power an amp puts out in 3 channel applications, how would anybody know how to design a system with a 3 channel amp? Also, dude take a chill pill I don't want you to have a heart attack.

ok, forget the crossover. If you had the exact same load on all 3 "channels", then the combined power from the amp will be split 3 ways. If you can't add that, find a calculator and a facilitator to help.
But that's a totally worthless number because of the stuff I mentioned 3 times above. It does you no good, and means absolutely nothing.
