do you by chance have the factory BOSE system? if so it could be that you did not wire up the Bose amplifier i believe its the pink wire comming off the small harness that does not get plugged into the aftermarket harness

Any but you will need an "auto leads" converter lead.
The factory radio on a 1987 Mercury Grand Marquis is made to play local radio states and cassette tapes. It is connected to a high fidelity sound system.
The secret is finding the right wiring harness, Metra 70-5600 and there are others. Local auto part stores do not carry it. You can find it on-line or at car audio specialty stores. Installation is relatively easy using the wiring harness and installation kit. Do not try and cut any wires or you will be lost in the maze of wires behind the dash.
Try resistor spark plugs.
Did it work before you replace the radio? Is the radio an original equipment radio? If it is original equipment, the radio wasn't the problem, the sound processor under the dash was. If it's an after market radio, you need to bypass the Infinity sound processor or make sure you have a wire connected to remotely turn on the sound processor. If none of this is the problem, check the fuses. In most cases, Chrysler recommends not running your after market radio through the Infinity premium sound system as does G.M. and Ford. You over load the processor and not only that but the ohm rating for your speakers doesn't match. Hope this helps

A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.
you need to make sure tat the factory amp power (remote turn on) wire is connected using the blue wire off of the afermarket radio
Sound systems and other after market products can be purchased and installed through the dealership where the car was purchased. There are also auto shops that specialize in sound system installation which can be found through local directories.

yes,because radio is an example of sound energy...
