Where is the best place to shop for good cables? Would electrical wiring be sufficient for that kind of lenghts? Gauge needed for that length?
If there is an electrical supplier near you, like the ones small construction companies buy their supplies from, then that will be the cheapest way to buy cable, usually in spools of 250ft or larger.
www.awcwire.com is a good online company but shipping electrical cable by UPS/FedEx is expensive.
I assume you want your cables to be safe for indoor and outdoor use. I suggest SJOW type cable, which is flexible, "junior hard service" grade cable, resistant to oil, water, and sunlight.
As far as daisy-chaining speakers over this huge distance, don't do that. Build a patch panel or a few simple "speakon splitter boxes." If you run 2 ohms worth of speakers on a 200 foot total length of cable you will lose an appreciable amount of power even with a 10 gauge, and it's hard to fit any larger gauge, durable cable into an NL4 connector.
www.audiopile.net is a good place to buy speakon connectors and other misc items from. They also sell bulk speaker cable, but I don't think it has a rated insulation and might not pass an electrical inspection.
