The primary source of this electricity is the vehicle's battery. When the engine is running, the battery is charged by a part of the engine called the alternator. Before it is distributed, the electricity travels through the fuse box, where fuses on each circuit prevent components from receiving too much power in the event of an electrical disturbance. Different wiring harnesses then distribute the electricity to the engine and throughout the vehicle.

While OEM and aftermarket wiring manufacturers alike combine multiple devices on single circuits, they take various things like current draw, wire gauge, and fuse capacity into consideration. For example, adding accessories to an existing circuit may require a greater-capacity fuse, which may cause problems if that fuse’s capacity exceeds the capacity of any single wire in that circuit. Should a wire find ground or its accessory fail in such a case, the wire may catch fire without ever blowing its circuit’s fuse.

The electrical system is a complex but essential part of what keeps your car starting, running, charging and doing the little, but important, things like locking the doors. And while voltage in automotive systems is much lower than say, household applications, it’s still important to enlist the guidance of a professional when making a diagnosis or beginning repairs because many components are extremely sensitive and can be easily damaged without proper training and knowledge.

You will also want to leave enough room around the sides of the amp to connect wiring and make adjustments for boost, crossover, and other factors. Typical amplifier mounting locations include under the passenger side dash, under a seat, or in the trunk or hatch area. There are pro's and con's to each choice. Under the dash or seat keeps the wiring to the receiver shorter, but can be awkward to install. The seat may need to be temporarily removed. The trunk/hatch area is easily accessed, but wires then need to be routed the length of the vehicle. Cargo capacity can be compromised.

Now you have isolated the problem to the relay and only two things can be wrong: either the relay's coil isn't energizing (due to an internal broken wire) or the high-current contacts are being drawn together but no current is passing through (remember high-resistance connections?). If the coil is bad the relay must be replaced. If the contacts are charred, file them smooth.

There’s nothing wrong with a one-wire alternator but theoretically they aren’t as effective as their OEM-style counterparts of equal capacity. It’s because one of the additional wires in an OEM-style alternator senses the system voltage.

It has a lower melting point than the wire itself. The size of the conductor is calibrated very carefully so that when the rated current is reached, enough heat is generated to melt the conductor and so break the circuit.

Every car audio installer, indeed, every automotive professional, will always recommend this first step: disconnect the battery by removing the negative battery cable. You want to do this in order to avoid any possibility of a short circuit. Remember that on many late-model vehicles, you will need a "radio code" in order to reactivate the radio.
