Wiring Diagram For Ceiling Speakers
There are a number of ways to wire ceiling speakers. You can choose to use bare speaker wire, banana plugs or spades.
Before you begin, make sure your drywall ceiling is free of obstacles such as pipes or wiring. It’s also a good idea to test the area using a stud detector.
1. Connect the Speaker to the Amplifier
A speaker has two terminals, one that sends audio signals and the other that connects to the amplifier for the amplification of the sound. These terminals are color-coded red and black.
The simplest way to connect speakers to an amp is by using binding posts or spring clips. These wire terminals are easy to use and are found in most speaker boxes, amps, stereos, and other devices.
To install binding posts, strip the wire to about 3/8” or 1/2” bare, and twist tightly by hand to keep the strands together. Be sure not to use a “twist and tape” connection method, as that can cause oxidation, power loss, and even damage your system.
To install quick disconnect (slide connector) tabs, heat the wire-tab junction until solder flows freely and covers most of the wire end at the metal tab. Once cool, add heat shrink tubing or other insulation to the tabs and slide them over the plug shell. Press the tabs together as needed for clearance inside the shell.
2. Connect the Amplifier to the Power Source
The amplifier you buy may have a wiring diagram that guides you through the process of connecting it to the power source. This may include a battery or a power inverter.
When connecting an amplifier to a power source, you need to use a wire that is thick enough to accommodate the amp’s demands for electrical current. This will ensure that the amplifier puts out its rated power and can operate properly.
You should also be sure to run the wires carefully. Make sure that all connections are secure and that there are no stray wire strands that could lead to a short circuit.
You should also be sure to match the positive and negative terminals of your speaker wires. This is important for proper operation and for sound balance.
3. Connect the Power Source to the Speaker
The best part about powered speakers is that you get to choose from a plethora of high performance offerings. For the aficionados out there, there are a myriad of options to choose from including in-ceiling speakers, floor standing towers and home theatre systems on the high end of the spectrum. Whether you’re looking to upgrade your aging acoustic wares or aspire to build your own multi-room audio system, these hpye powered beauties are a breeze to install and maintain. With a little know how and the right tools in hand, you can be in the speaker business in no time.
4. Connect the Speaker to the Switch
Once you have your amplifier and power source connected to your speaker, it’s time to connect the speaker to the switch. It’s not a complicated process but there are some things to keep in mind.
First, make sure that you have a ladder and a stud finder to inspect the ceiling joists for wiring. This will help you determine where to install the wires for your speakers.
When you’re ready to run your wires, use a quality cable that has low resistance. Leave extra wire to allow for future wiggle room.
Next, connect the positive terminal on the first speaker to the negative terminal on the second speaker. This is called parallel wiring and is the easiest way to connect your speakers together.
You can also use series wiring to combine the positive and negative leads of all of your speakers at one time. This is recommended when installing multiple sets of speakers or when distributing sound to several rooms.
