I'm planning on running 2 zones outside. 1 to my deck, 1 by my fire pit. I've been looking at running 2 wiim amps, but if there is an audio delay, it would be a nightmare. I read that there is an on board mic for this, but my equipment will be in my network closet. Has anyone ran an external mic in this situation? One run will be about 50 ft. The other about 150'. Also what sub amps does every one like at reasonable prices for inground subs?
