Audio Systems: amps, hook ups, stereo amp

Question
i know how to do all the dual amp hook ups except whick amp do i hook the speakers into and do i still bridge them

Answer
Not sure I understand your question.  Are you talking about bi-amping a 2-way speaker or are you talking about using a stereo amp for driving two separate speakers?  Or something else?

Bridging is for converting a stereo amp to a mono amp; the speaker wires are connected, in bridge mode, to the two plus (+) terminals.

Please let me know if you have further questions.
