I am planning on buying a crossover in the next week or so. I have a GK 400RB head and a Carvin DCM1000 power amp. The 2x10 (highs) are run off of the GK's poweramp, and the 1x18 (lows) are run from the Carvin. Would effects send to crossover work? Then run the highs back into the effects return? I originally ran my DCM off of the effects send, but it didn't have enough gain (I think), so now I use my direct out (post eq) to go to the DCM. Any ideas?
