The basic speakers built into televisions are generally too small and inadequate to deliver high-quality audio or to fill a room with sound. Fortunately, connecting different speakers, like surround sound or a stereo system, is fairly easy. This information applies to televisions made by many manufacturers; including but not limited to LG, Samsung, Panasonic, Sony, and Vizio. You'll likely need a foot analog audio cable with stereo RCA or miniplug jacks. Once all the tools are available, hook up the speakers to the TV using the appropriate audio cables, and then power on the TV and speakers.

How to Connect a Stereo System | Stereo Barn
I started working for the Stereo Barn in late I knew the red wires went in the red holes, black wires in the black holes, and that was about it! Well, everyone starts from somewhere and after assembling and disassembling numerous demo stereo systems I learned pretty quickly the ins and outs of a stereo system and how everything works together to make your music sound the best it possibly can. What I realized is a lot of people who come to our store looking for a stereo system may not have the slightest clue how to set one up. Understandably, they have not had many years of experience connecting stereo equipment on an almost daily basis to learn how to do it themselves.
How to hook up a subwoofer to a stereo system
A subwoofer can really enhance the sound of any stereo system. Even if you have high-end speakers and amplification, a subwoofer can add the deep bass that you may be missing. Connect using a line-out connection. This type of connection will send a nonamplified, low-frequency signal to your subwoofer.
You don't necessarily need a receiver with subwoofer output jacks. Subwoofers are used in most home theater systems, but subs can also radically improve the sound of stereo systems -- and not just the ones with small speakers. Subs can provide a foundation to the sound that few speakers can muster on their own.
