It pays to install high-quality in-wall wire — you don't want to tear into your walls to replace it later on. Monster's quality build includes high-purity copper strands that offer increased flexibility and maximum conductivity. Plus, twisted pair construction minimizes problems associated with radio frequency and electromagnetic interference.

Designed for easy installation

Monster created their in-wall cables with the installer in mind. Sequential footage markers simplify measuring. A special "rip cord" allows you to quickly pull apart the jacket to strip the wires. And the low-friction jacket makes these cables easier to pull through your walls.

Keep your home and family safe with in-wall-rated speaker wire

When you're running wire inside your walls, it's important that you use speaker cable that's approved for in-wall runs. This cable's CL3 certification means it passed safety tests administered by the Underwriters Laboratory (UL). The UL considers factors like the amount of heat generated by current flowing through the wire, how resistant the cable is to catching or spreading fire, and its susceptibility to damage from external stresses. Also, be sure to check your local building and fire code and buy wire accordingly.

Monster Cable 16-Gauge 2-Conductor In-Wall Speaker Cable

Written By Drew, Memphis, TN on Thursday, June 28, 2012

Crutchfield Customer Review (What's this?)

Good value for a long length of speaker wire.

Pros: Strong copper strands don't break off when stripping or twisting the ends. Length marked clearly every foot.

Cons: Tangled a few times inside the box while pulling through the opening.
