Okay.  Test the speaker wires to make sure the speakers are okay.  If you can't measure any ohms on these wires, your speakers are probably blown because I don't remember seeing a factory amp in this car.

If the voice coil is open, you wouldn't get any sound.  Have you verified there are speakers in there?  I had a kid bring me a Mustang to do an amp bypass, but some of his speakers were missing.  Just a thought.

is the aftermarket new? you still have the problem of no power to the aftermarket  hu? are you planning on keeping the factory hu or do you perfer the aftermarket. if the radio was missing chances are he had an aftermarket him self and who knows what he did. missing speakers bypassed factory wiring. geepherder is diffently right by verify\ing if there are speakers in that car and you will need to verify that factory wiring is in tact if you inteand on using that harness to bring sound from hu to speakers. if the aftermarket is old hook it up to a 12vdc power supply or battery and see if it works. if you want you can use a 9vdc battery to the speaker leads at the harness to get a reaction out of the speakers just in case the factory hu has blowen outputs. lol
JUST ONE MORE AMP!!!

There are no missing speakers. all the speakers are connected. I still have no power to the aftermarket hu. the factory wiring are intacted and when I connected the stock radio it gets power but no sound. the aftermarket has a 12volt wire but I did not connect it to the battery its connect thru the harness 12volt. can I just take the 12volt wire from the aftermarket and connected to my constant power cable under the steering wheel instead.

you need to check the wires from the cars harness with a DMM to insure that you have constant 12v, switched 12v, and a good solid ground.  from there you can determine if you need to replace a blown fuse or possibly running wires to the ignition harness of the vehicle and ground to the chassis.

It sounds like you're looking in the wrong area then.  You say the units both power up, you just get no sound, so you know that you have constant, accessory, and ground. 

That being said, I think the easiest/best solution would be to forego the factory amp and just run fresh speaker wires directly from your radio to the new speakers.  Even before you do that, though, you can test the speaker outputs with a speaker to make sure they are working.

i think what he meant was the aftermarket HU doens't power up from the previouse post...just a thought though...is there a fuse on the back of the cd player your trying to install? i fixed a guys cd player in a 96 cav that the fuse on the back of the deck itself was blown. (it was an older JVC)  and just for something in left park but i've seen it happen...hows the connections inside the wireharness you put in? we had one at a shop i use to work at the the pins pulled out very easily...maybe one has slid back far enough not to allow power to your deck and when you replace the aftermarket deck and put the factory one back in you remove that harness and remove the prob...just my 2 cents
