Amplifier and Subwoofer Cables for a Home Theater

Learn how to identify the best cables to produce good sound in your home theater.

One of the most difficult things to set up in a home theater is the speaker system. You have to know exactly how many items you're going to need, what brand or make you need, where you're going to put them in your home, and what cables and their lengths you need for the installation process. With these factors to be considered, it's no wonder lots of people get it wrong the first time.

Location is everything. Look for cables with an identification system; it usually has color-coding, which labels channels and phases. Organizing them is essential for an error-free hook-up of the many speakers needed in a home theater. The main left&right speakers should always have the same cable length to avoid unbalanced audio reception. Placing the amplifier & the subwoofers too close to the system would be a bad idea, as they are prone to acoustic feedback caused by vibration.

Amplifiers should have a longer cable, or at least longer than the main speakers, because they are more vulnerable to unwanted feedback from other audio devices, even cell phones, causing loss of sound or degradation of quality. As for the subwoofer, it should always stand close to the amplifier for better quality, but not too close, again, just to avoid unnecessary feedback from the system.

The speaker that's making the distinctive loud bass sound is the subwoofer. It amplifies by using only low frequencies from the audio source. The only difference between those two is without the amplifier, the subwoofer would be useless.

What cables do we need to hook up an amplifier to a subwoofer into a home theater system? First, we should take into consideration what kind of home theater system we are going to use. Once we know, cable identification would go smoothly.

  • Buy a speaker cable with a large gauge. Remember the smaller the gauge the larger the conductor inside that can meet the required power of today's home theater systems. Same process goes for the cables to be used in the amplifiers & subwoofers.
  • Buy the best cable you can afford. The optimum level of the cables you may plan to use should at least be in the same level of the speakers and apparatus you are going to buy. Try to increase your budget for cables because it can save you money from re-buying another set of cables (in case of damage, of course).
  • Get cables that have channel identification. This will reduce the hassle of guessing where you should connect the cables. Having diagrams of the home theater system also helps, as long as you bought cables that our compatible with it.
  • Make sure the cables have 24K gold plated connectors. This gives the optimum signal transfer and ensures a secure connection to all jacks. As for using exposed copper wires, they're only better during the first months after buying it. Though the gold plated ones are a bit more expensive than the copper, it can save you from unwanted damage due to oxidation. With damage, you have to buy another set of cables. That can cost you heaps of money.

Having amplifiers and subwoofers in your home theater system will drastically improve the quality of entertainment you'll get every time you use the components. Expect better output sound the next time you watch a movie.
