I'd like to use the analog audio from the 811 to run some outdoor speakers (that I haven't bought yet...), but am unsure how to do this. I'd like to have my Sirius Big '80s :listening outside with me while gardening/swimming/working on the water feature/etc.. Currently, I have the analog hooked up to the TV speakers, but I never use them. I like the rock-shaped speakers, but the bass will also be important. It's probably 50' or more from the 811 to the area where I want to use the speakers, if that matters. What's the best/easiest way to do this without breaking the bank?
