Wiring speakers, is CL2 cable necessary?

[ES_Revenge]

I'm going to be wiring my rear speakers under my main floor (into the basement) to go from one side of the room to the other, without seeing any wiring.

I already have banana plug wall plates and everything and I know how to run the wires and am fairly electrically/mechanically inclined so no problems at all there with the installation.

The only thing I'm wondering is if it's advisable to use CL2 rated, jacketed speaker wire ("for in wall installation")? Obviously that's what the wire is for, but I mean any speaker wire will do really, I'll be using 12ga wire, and speakers wires don't really carry the current to pose a fire hazard. Though it isn't a huge deal to get CL2 jacketed cable, I already have enough normal speaker wire to do the job so I wouldn't need to buy anything if I didn't use it.

However it is a new house and from a home insurance standpoint (or perhaps even a building code standpoint), should I be using CL2 cable to ensure I'm not somehow bending or violating the policy/code? I mean it's just speakers and usually I wouldn't think twice but this time I did, lol.

the extra jacket on CL2 just helps protect the wire when running it, it is just more durable than regular single jacket wire.

If your careful you can get away with regular wire, or even use something like low voltage lighting cable they sell for outdoor noma lights at home depot.

There wont be anybody inspecting your wiring because its after the fact so its really up to you. Theres no harm in not running cl2.

In-wall wire doesn't cost that much more, so you might as well just do it. It's more durable as loudsubz said. Do it right!

Main reason for CL2 or FT4 wire is because it meets NEC standards (fire code)... Main difference between that and standard cable is that rated jacket meet the smoke/flamability criteria of the NEC where as your typical jacket does not... But as the boys mentioned above, you also gain the benefit of having a more durable jacket for pulling the cable as well.

Also, any particular reason you're going with 12 ga? If your run is less than 25 feet, you can quite easily use 16 ga and save quite a bit if cash.
