Thats why i'm gettin passive x-over's made for the setup... plus i'm not looking to drive a ton of power to my sub.. 150 will be fine. Plus the speakers don't need to handle a lot of power. They are 30w rms.

I have heard many positive reviews about people using tri-mode setups.. this place even installed a few and said the customers were quite happy.. the only people i hear saying not to go with it are ones that just base thier info on pure facts and no trial / error.

anyways I have been thinkin more about It I might just scrap the tri-mode idea and just power the front's off the hu and give all 150x1 rms to the sub... the specs on it are 150w rms long life use.. 200 w rms .. and 400 peak.. would I risk damaging by underpowering them if the rms is at 200?

Why does everyone here say Tri-mode sux?
First: you can have 40/ch for highs, and 150 for bass, but NOT at the same time! If you are using all your watts(150) playing bass, then an additional 80 added to it will cause your amp to clip. so you will only be able to get about 1/2 the power out of your amp (a 3dB loss)
Second:With a bi-amped system, you can "overdrive" your sub amp up to around 5% distortion, and get up to nearly double the power.With no highs connected to the amp, this distortion is inaudible. (This equals about a 3dB gain.)
Third: The Passive crossover you are buying for $10 will be probably 18ga wire, and will lose about 3dB.
Add it all up and the Bi-amp is about 9 dB louder (nearly twice as loud)as the Tri-mode setup, or the eqivalent of 8 times as much power. (each 3 dB change doubles the power required)

I will state that it will not make any sense for you to use Tri-mode with an amp that is 40x2. Especially if you are concerned about transient response.
You would have to have one hell of an effiecient woofer. I am not familiar with the cadence in question?
And like Haunz said the box.
Like I said before... Deck power and bridge the amp for the sub.
And my old soundstream that I was not happy with in tri-mode was 125x2 500x1
