I have a question for those of you home stereo knowledge.
I want to mount waterproof outdoor speakers for my backyard and patio. Because of the size of the yard, I want to run two sets of identical speakers at the same time.

Specs here:
Power Range (watts) 10-200
Sensitivity 92 dB
Impedance (ohms) 8
Frequency Response 40-30k Hz

It has been decades since I was into this stuff and don't remember the details.
What specifically do I need to look for on the back/spec sheet of a receiver/amp to sufficiently power these at the same time?
I think I need: A+B: 8 Ohms min at speaker, 100RMS per channel @ 8 Ohms, etc...
Thanks,
Dan

Thank you. I think 100w will do since I have neighbors on all sides. Keeping it simple Mainly want radio playing with ipod on the line in. I don't want to spend $500 on a receiver so am looking on clist for a used one. But I need to ensure it can power four 8 ohm speakers. Trying to remember how to read the specs.
