I have Focal 165V speakers.
70 w rms or less . closer to 70 the better
well speakers have a 0-55 speaker nominal witch is the range of power most stereo's give to each speakers. your speakers have a 140 watts max. sense your RMS is high just about any 4 channel amp that has 140x4 watts max will work for these i have a perfect amp for these with a really good price.
