I posted a few weeks back about not getting any sound out of my aftermarket CD player. Some replies were the cd player is bad send it back for warranty work. So I did. Also in the mean time I tried another aftermarket CD player, same thing. The units are powering up but I get no sound. I checked my wiring 15 times, nothing is wrong. Put the factory tape player in, works fine. WHAT THE HELL!?!

There maybe a factory amp that is not getting power. I expierenced that when I put in a stereo. If you got the wiring harness adapters check to see if there is a wire that should have power going to it that controls the amp.

Make sure you have the correct wire harness ? Try a after market amp that would be a big help and sound better. Do you still have the factory speakers are after market if you still have the factory speakers they would take about 75-150 out put amp. but if you have after market speakers they should have there peek power and watts on the magnet of the speakers

I had the exact same problem. Took a bit to figure out. Those new units only get power/function with that harness you have; that's it. Your speakers are run off a seperate harness. On my 89 I took out the stock radio/cassette player, and also discarded my stock amp that was sitting directly in behind the stock radio. Up in behind that amp again is another large harness. Look hard, mine was tucked up in there pretty good and I had to haul part of it down.

That one is for your speakers. Unplug one of your connections that you have going into the harness already (you have one wrong) that you got with the new cd player, and plug one of the connectors off the speaker harness into that first harness and you'll have power to the speakers. My friend tells me he's quite sure he never had to bypass the amp on his 91, so also take that into consideration......90-93 may be different. I don't know if their amps were built-in. .....so if someone could set me straight on that one I'd appreciate it. Thanks.

Well i worked for a oem radio shop that delt with ford and the other makers. On most cars from 85 and above the Ford radios are amplafied by a factory amp. Previos post is right thefactory radio controls the amps to the factory spekers ur best rout will be like they said put an affter market amp run new wiring if posible you will get better sound. The other rout is finding the wire that powers up the amp from the oem radio and hok it ip to the switch so that wen you turn the car on ill power it up. But the sound is better with aftter market components.
