On the player there must be the loge CD-R compatible. If not, it wont play CD-r disks. Normal CD's have a metallic reflector layer, giving a high contrast. CD-r disks have a dye, that will be changed in colour by a laser, giving a lesser contrast. When the laser and detectors in the player is not capable of reading the lesser contrast they can't play CD-R disks. Most older players can't. Sony is one of the manufacturers who deliberately kept there players incompatible with CD-r disk the longest.

the stereo has an input channel on the back and the speaker wires go into that

Hi you could try this.

You can double check by measuring the voltage on the outputs playing a 60Hz test tone at full volume. You should get around 7-10 volts AC. I have a 60Hz tone .Mp3 link on my site - http://sparky3489.webs.com/settinggainampclass.htm

contact sony .... or check your head unit is recieving

Is the amp getting hot? If so, move it to get some air.

Depending on the amp, you may have a bad ground on the rca's. The best way to determine if you have a bad rca ground it to run a wire from ground to the outside ground of the rca. If it stops pulsing, you have a bad rca ground in either the amp or the head unit (radio).

I would check Crutchfield for a wiring adapter. They sell adapters that go straight from new stereo receivers to the factory wiring harness.
