If you are planning the installation of a new amazing sound and video system in your car, you have to consider the wiring that it entails.
A little expert advice on wiring your stereo and speakers will help you achieve the quality of sound that will make others green with envy.
The speaker wires
If you have existing speakers connected to your stereo, you would probably utilise the existing wiring to connect the new speakers and audio receiver.
If you are replacing your receiver, you might find some harnessing that can act as an adapter between existing wiring and the new wiring to your car audio receiver.
Car audio systems are more often than not quite similar, which makes it not too troublesome to connect with new speaker wires.
Electrical and Powering
It is important to keep in mind when installing a new system or adding a new sub-woofer, that your powering needs may increase.
High-wattage amplifiers will draw more power which will change your wiring needs. You may have to use a lower gauge wire that will deliver more power.
Connector Cabling and Wire Gauge
Connector Cabling: As an addition to regular speaker wire, you could upgrade the cabling from the receiver to the power amplifier.
If you want to prevent distortion, you should use a cable with good insulation before the signal relays to the rest of the audio components.
Wire gauge: Most pre-installed audio systems use 16-gauge and 12-guage wires. 8-Guage wire works best for powering all but the smallest of amplifiers on an audio system.
A lower gauge number means a thicker wire, lower electric resistance but more power reaching the speakers and amplifier. Match the resistance rating for your amp with the resistance of the speaker wire.
Types of connectors
The gauge of wiring you’re using will determine the type of connectors you will need to connect to the audio components. You may need spade and flat connectors, in-line fuse holders and battery terminals.
Consult your amplifier’s installation guide to ensure you have the correct wiring and connector types recommended for the components you are using.
While the car’s motor is running, the alternator powers your sound system and the rest of your car’s electrical system.
Mostly you don’t have to worry about the battery providing enough power to support the audio system’s amp, however, when the car is turned off the battery becomes the sole source of power to the sound system.
If your audio system draws excessive power, your battery will run flat unless you install a second battery specifically for your car audio system.
Upgrading your alternator
Should your sound system draw too much power from your car’s battery, you can look into solving the problem by upgrading the alternator.
Depending on your vehicle’s make and model, replacing the alternator can be a simple task.
Try finding an aftermarket alternator that can accommodate the increased power demands from your amplifier.
How to wire your car audio system
Another common problem that you could face when installing a high-powered sound system, is excessive vibrating.
You can minimize this problem by installing sound-dampening materials to line your trunk and door panels.
