The purpose of any wire is to transfer current a certain distance with the least amount of resistance. The more power and equipment you have, the larger the wire needs to be. What can happen when you use too small of wire size for your equipment? We’ve outlined a few points below why we make it a priority to keep you and your car safe when installing equipment.
Using proper gauge wire is very important for several reasons.
- If too small of a size is used, the wire could melt because of the large amount of current flowing through it compared to how much the cables can handle. The smaller the wire diameter, the higher the resistance there will be to the flow of energy. When you have high resistance you create heat, which can turn into a fire hazard. A good example of this is a toaster. You definitely don’t want your vehicle turning into a toaster with you inside!
- Damage can occur to the amplifier when there is not enough current flowing to its circuits, especially when the music peaks. The amplifier needs a boost in current which the wire size might not be able to deliver. Also, If there is a lack of power and the grounds are not isolated well enough, the 12V ground could leak current into the the signal ground and blow the amp.
- If the incorrect size is used, your amplifier will not receive the proper voltage that it needs to perform at it’s capability. This means the sound quality of your system will be compromised. Voltage refers to how much work can be done by electrical current, so if the voltage is too low, there won’t be enough to power your amplifier. What is the point of a great sound system when it doesn’t produce a great sound?
