I want to bi-amp my setup in a non-conventional way. I am currently running a hughes and kettner bassbase 400 into 2 H&K 4x10's. I want to seperate the two cabs so different signals go into each. What I am planning is to use my bassbase for my dry/clean signal with an emphasis on the low end of my tone running to the bottom 4x10. Then run a small poweramp/preamp setup that will focus on my midrange/effects into the top 4x10. (I use alot of distortions and other effects) I am wondering if a 150watt power amp would be enough power to drive my upper midrange and above frequencies + the effects. I have tried something simaler to this once by using a guitar half stack for my high range freq and sending the lows into the bassbase and the 8 10's and I noticed I did not need nearly as much power out of the guitar amp as I did the bass. Basically I would like to know if anyone thinks this idea would work or if a 150watt poweramp would not have enough power to pull off my idea. I guess this is more of an opinion question overall, but any feedback is greatly appreciated.
