so i just put a new kenwood cd player in my cutlass. hard wired it into the factory radio harness then running an all-time hot wire to the fuse box. with the car in the ACC position or ON and not running, the radio plays perfectly. start the car, no sound. sometimes it will go into protect mode, sometimes it still plays but nothing comes from the speakers. turn the engine off and turn to the ON position, it plays fine again. i know when it goes to protect mode, its supposed to mean theres a short in the speaker wires. ive unhooked all the speakers and just hooked up one speaker right by the radio, same problem. ive added an extra ground to the radio thinking maybe it had a week ground, same problem. check all my grounds under hood, same problem. even thought about an alternator problem since thats the only difference between running and not. it was charging low so i replaced it, same problem. i took it to the car audio shop where i bought it. their installer (which has been doing this for 20 yrs) went all over the car with a multimeter and couldnt find a problem. so, thinking it must be in the stereo, they replaced it. same problem. im out of ideas and so is the installer. any help??

strange voodoo there i am not by far a knowledgable source in sterios , how did the previous sterio and speakers operate? same speakers ? same wiring?
the old original stereo worked perfectly. put in a new stereo with all new speakers also with the old wiring. still cant figure it out.
when you say all time hot wire do you mean the 12v constant for keeping the time and radio stations in memory? if so i always run that wire to the cigarette lighter to the 12v constant there. when you have it wired directly to the fuse panel it may see to much juice and shut down so it doesnt fry the unit.
Wiring it directly to the battery wouldn't fry it, unless there was too much voltage... in which case everything else would get fried too. The fuses are there so if it draws too much current you don't fry something. Voltage and current are two very different things.
i know what your saying doober, im just saying if he has the memory wire, wired directly into the fuse panel. the 12v memory wire does not have an inline fuse the power wire does. some units have an internal safety feature to protect against voltage spikes.
