How to add Klipsch Heresey to Fisher Futura?

[Earbleed269]

I recently acquired a pair of Klipsch Heresy 1’s.

I am a little confused as to the proper way to add these to my fisher Futura console when I connected them it seemed they would not generate enough volume even when turned up very high looking for some tips and advice on the best way to properly get the best sound out of the speakers

did you disconnect the internal speakers? If not, do that. It probably can't run both sets effectively.
