Insignia is the brand of televisions designed and sold by Best Buy. You can only purchase the line of TVs from either in a Best Buy store or online from the Best Buy website. If you own an Insignia television you may want to connect a speaker system up to the TV. You can do this is very little time, without the aid from a technician or the Best Buy Geek Squad installation specialists.
Look at the back side of the Insignia TV. There is one audio output located towards the bottom of all the connection ports.
Plug the red and white audio RCA cables into the audio out ports. Make sure the appropriate colors of the cables are connected to the same colors of the ports.
Insert the other end of the cables into the audio inport on the sound system. If you are using a surround sound system it more than likely has multiple audio inputs. Connect the cables running from your Insignia TV into the "TV" audio ports.
