aside from cost, what is the difference between this and their other cables? it is half the cost, but uses Aluminum versus solid Copper wires. i am running a 1300 watt sub amp and a 400 watt multi-channel amp, and i was wanting to do the big 3. will this cable work for me? if so, should i run this size cable back to my CAP and distro block for power and one for a ground distro block for my two amps? thanks.
