I put in a NEW RADIO IT'S A KENWOOD BUT THERE'S NO SOUND TO THE SPEAKERS .RADIO TURNS ON AND EVERYTHING WRKS BUT NO SOUND.

check if your car has a stock amplifier and if it turns on. if it is on and you still get no sound check that your speakers are not touching ground.

Disconnect the speakers and try it with another speaker or speakers not in the truck. If it works, the speakers or the wires to them are messed up. If it doesn't you probably damaged the output capacitor in the radio by turning it on without speakers attached. Realize that the speakers are part of the radio circuit and act as resistance. Without them, there is no resistance and it puts a strain on the radio.

their should be a blue and blue white wire on the Sony radio. cut the blue wire and then connect the car side to the blue white wire and tape off the blue wire that is on the radio side.
the blue wire only turns on when the radio is activated. the blue white wire is activated when the radio is turned on.
please rate my solution.

Sounds like the music amplifier is different to the tuner audio amp. The music amplifier is now looking at an unbalanced impedance which is less than it should be. Therefore the output chip of the music amp has more current through it than it wants so it gets hot and shuts down.Put a four ohm wirewound resistor ( from Radio Shack ) in series with each surround speaker to reduce the current flow through the amplifier output.

lay out new speaker wires and that way bypass the amp altogather Kenwood radios have power to move speakers without an amp

I would try hooking up another speaker, not from the car to check the audio output of the Sony.

If you had followed the directions correctly and the old speakers worked as well, take the new radio back for exchange

as the tv stations that were being feed into the system were digital and the nput was actually analgoue 2 optical cables are required.
have tv sound and blue ray sound through surround sound when tv channels were changed to analague.

go to standby hold m-log button tell menu comes on display press up on volume control tell amplifier comes on display pess left on volume control tell display says amp on. the built in amp on the stereo turns of and on to provide better sound quality to the pre-amp out puts

You may have Power antenna and amp remote turn on wires switched. Your system may be looking for turn on signal from radio and only gets it when am or fm is on because power antenna wire is hooked up instead of amp turn on signal.
