i just put a deck and there is no sound so then i hooked the speakers directly to the deck to check if they were working and they were fine so i don't know why there is no sound when i hook it up to a harness.. if any body can help me that would be great.

does it have a factory amplifier? some stock audio systems have a small amplifier built into them - you have to provide some sort of turn-on power to it before your speakers will work.

I had the same problem, but i still had Radio.

Do you have Radio and no CD?

On mine, it is on the left hand side of the trunk, if you are looking into the trunk. There is a carpet lining aorund your trunk, you have to peel it back, to reveal this:

That big black square to the left is your rear speaker. The black box to the right is your amp.

ok you bought a wiring harness for the new deck, right? often there's a blue/blue-white wire in it, that is described as the 'amp turn on wire'. look on the back of the harness to see if either of those 2 wires has a corresponding wire in the stock harness. if one or both of them does, then try turning the car to acc. and jumping one of those blue wires to +12. if you get sound, then great! wire that wire to the amp turn-on wire of the new deck. if it doesnt work, try with the other wire.
