I'm not sure exactly what info your looking for but....red wire is 12V igition power, yellow wire is 12V constant power, black is ground. The rest of the wires will be something like green/green with stripe, blue/blue with stripe,purple/purple with stripe, white/white with stripe. Those will be the speaker -/+ wires. If you hook up red/yellow/black you can do some trial and error to figure out which wires are for which speakers.
