I need help determining how to connect a second set of speakers (outdoor) to my main set-up.

I currently have a Rotel RC1070 pre-amp and a Nad C270 amp with M60's.

I want to connect a set of outdoor speakers to this system. From what I have read here I will need to run a cable from the pre-amp to another amp outside to power the outdoor speakers. What I am tentatively planning on doing is getting a small integrated amp outdoors (it is in a covered screenhouse).

I have two questions. First, the cable run from the pre-amp to the integrated amp will be approximately 50 feet. What do you recommend for cable?

Second, do you have any suggestions for configuring this system other than what I have proposed?

Thanks in advance for your help.
