Looking for input on my system idea. We built a pool shed that is 16'x'14 wide, not onyl 8' feet of the 16 is storing pool floaties and such, the other 8' is a covered area whis we are going to put a bar into. Now I want to install a sound system first that way i can have some tunes while I build the bar. So my thought were to but a set of 150watt speakers from outdoorspeakerdepot, a 400 wat amp, a Jenson waterproof boat stereo, and a 12 volt power supply to power it, that way all my electronics will be in the unweathered area of the pool shed and only radio and speakers will be exposed to the elements. Any thoughts?
