Amplifier Wiring Diagram
A typical 2-amp setup
This simplified diagram shows how a full-blown car audio system upgrade gets wired in a car. The system includes a 4-channel amp for the front and rear pairs of full-range speakers and a mono amp for a subwoofer. Capacitors aren't usually necessary in a car stereo installation but we included one here to show how it would get wired into a system.
