I just purchased a 12 ga. wire from parts express (CL3 rated, unshielded). What's the unshielded stands for? Is it okay to run them across power lines (like 110 outlets)?

I appreciate the input guys.

Running them parallel is your best bet to avoid any interference, but I do believe the code says that they cannot be closer then 15" to any 110v line.

A drop down from the floor above or up (from below) might be your best bet.

Unshielded means that there is no metal braid or foil surrounding the conductors for the full length of the cable.

Almost all speaker wire is unshielded. Shielded wire would be a lot more expensive. Interference suffered due to unshielded speaker cables is extremely rare because the signal currents are very large (volts) compared with interference levels (microvolts or at most small numbers of millivolts).

Sheathed cable means there is a cloth or plastic jacket surrounding the conductors that are also separately insulated.
