Question about Kenwood Car Audio & Video
I don't mean ti intrude Linktriscuit, but your solution is OK for low power car stereo's.
I have been in car audio setup for a while and what daren_norman has said was that he needs a 15A seperate cable. So to my knowledge if his CD palyer manual says it needs 15 Amps then I don't think it's a low powered one, 15Amps is quite high for a standard car radio stereo harness, and that is why it needs a seperate high guage wire capable of handling that much current.
This yellow wire replaces ACC cable in the harness, but the normal memory supply (+12V) is taken from the harness and the cd player should have good ground connection to the body of the car in addition with th harness ground.
The yellow cable should be as thick as u can get to make cable loss minimum. At high Audio levels the cable drop will increase if you use low gauge wires ( thin ) and the sound will get distorted due low batttery supply.
And thirdly there will be a remote wire to switch on and off the cd player when u turn on or off the rest of the components
Mostly there couls be two or three different ways to control the set but THE YELLOW WIRE WILL BE THICK ENUF TO HANDLE THE CURRENT AND IT WILL BE TAKEN FROM THE BATTERY + TERMINAL THROUGH AN APPROPIATE FUSE TO THE CD PLAYER OR POWER AMPLIFIER. DIRECTLY, AND IT WILL BE NOT SWICHED OFF.
I said all these because car audio currents a quite high and any silly mistake will lead to cables to over heat and mostly it will catch fire. ( Cause I have seen a maercedes benz caught up in flames due to poor wiring. "what a dread ful sight, and a 2004 model two").
So If u need help just post back and I will tell u how to do it, it is quite simple with the right way.

You can test one of the wires from the harness connector for a contant +12v with a test light. They are sold at your local auto parts store for less than five dollars. The harness connector that i'm talking about is the harness connector that originally connected to the stock radio. All of the connections needed to install a cd player are all on that harness wire. The test light is simple to use, all that's needed is for the alligator clip to be hooked to ground. And from there, you can determine from tapping which wires are for the power supply. The power consists of three or four wires. They are ground, +12v ignition, +12v constant, and if installing w/ an amplifier, the remote. This is the usual place most people connect the wires for a new head unit.
