First thing you want to do is disconnect the power to your vehicle, which is the red.

Next thing is you wanna strip all your wires, an inch is good.

Then what you wanna do, and you can do this part in any order, connect the BIG red wire, should be about 22 feet long, in to the power of the amplifier, connect the ground wire, should be brown or some other color like that and about 1 and 1/2 to 2 feet long. into the ground part of the amplifier and then somehow get the other end of the ground clamped down to a metal part of the car, and the last wire, which should be blue, needs to be connected to your cd player so that the amplifier is running something, and make sure to connect your subs to the amp, BRIDGING is recommended for this part.

If you dont know what briding is, this is what it looks like-------> + - + - now to bridge you wanna connect your red speaker wire to the FIRST plus and your negative which should be silver/grey to the second minus, the reason you do this is it maximizes your sound.

Then finally you are going to connect to the battery, first, you should have another big red wire, 1 foot in link and a 100 watt fuse box, its small trust me.

At one end of the fuse you want to put the other end of that really long red wire into it and screw the screw down into it as tight as you can, and at the other end of the fuse you wanna put one end of that short wire into it and screw the screw down as tight as you can. and then you are ready for the last step.

Connecting to the battery, you will/should have round wire covers that are metal, you wanna take one of those and put it around the other end of that short wire and then reconnect it to the power of your battery.

You should be all set now to have a kicking stereo running in your car.

I hope this has been informative enough.
