When your hooking up a home stereo or car audio, it is good to know how to wire multiple speakers together. In order to get the best sound and performance from the amps and speakers, you need to figure what layout is best for your operations. You need to figure what loads your amp can handle, what power the speakers will draw, and wether you need a high or low Impedance.
Once you have all the information usually found on the back of the amps and speakers, you will need:
- Speaker Wire
- Wire Stripers
- Screw Drivers Philips and Flat
- Solder Gun and Solder
- Electrical tape
Choose your layout. There are three layouts to choose from, series, parallel, and series/parallel. Once you have your Impedance figured out, and what you need for ohms in your speaker lay out, you can make an informed choice. The series layout is a simple set up were you connect your first speakers positive to the amp, then the second speakers negative to the first speakers positive. You complete this circuit with the negative of the second speaker continuing the chain or returning to the negative of the amp. The Parallel, as suggested in its name, runs both speakers from the same channel of the amp. Both speakers run to the positive side of the amp with the positive side of the speaker, and negative side of the speaker to the negative side of the amp, working independently from one another. The Series/parallel is a combination of both. The difference between the to is running the speakers in series allows for less power to the speaker, and lowers the impedance of the speakers.
Shut it all down. Before you touch a screwdriver to any part of the amp, void any power to the sound system. Unplug it or disconnect the battery. This will protect you and the amp. If you are working with a twelve volt system with a capacitor, and high amperage, it could seriously hurt you. A 120 power supply is nothing to play with ether.
Hook it up. Going with the pattern you have chosen, begin hooking the wire to the amp. Remember what color you have to positive and negative. Most wires are copper and silver, while some are red and black. Strip back only a small amount of wire. The less you have showing the better. On the amp, Loosen the screw and slide the bare wire between the screw and the contact. Tighten the screw and tug to make sure the wire is held tight.
- Run the Speakers. According to the set up you need, pull the wire to the speakers, leaving a little slack for good measure. You need to strip a small part of the wire tip and insert it to the proper side of the first speaker connectors hole. Use your soldering gun to melt the solder and hold the wire firm in place. You can purchase tips for the speaker connections to slide on the speaker, but the solder holds better and makes a better connection.
Your speakers are now ready to use. For the protection of the speakers and amp, cover the back of the soldered connectors with a layer of black electrical tape. Do the same for the amp. This will make sure that if anything were to come into contact with the wiring of the speakers, it would not short out any key components to the system.
