I have a 2000 Tahoe and I recently hooked up a Kenwood KDC-X459 CD player and it sounded perfect with my kickers and factory speakers. Until I turned it up a little more than normal and the factory speakers quit working with just my subs working. After about 3 hours when I started my truck up the factory speakers worked again for about 15 minutes they they cut out again. Some people told me to check my wires which I did and still nothing.Any advice on what I need to do? Is it the CD player? HELP!!! Eric
Hey Eric, I had the same problem with my 2000 GMC Yukon and because of the OnStar connection in these vehicles you must get power to the factory amplifier which can be done by running a relay wire from the blue remote wire or the power antenna wire to either the pink or green wire on the extra pin adapter that you unplugged from the back of the factory unit. Hopefully you have figured this out by now but for future readers this solution should be helpful.

There is a good chance that your car has a factory amplified system, it may say premium on the speaker covers if it does. Check to see if you hooked up the bue and blue white wires in the adaptor harness. The blue wires in the adaptor harnesses are to turn on the factory amp.
You most likely have a shorted or damaged speaker, which is causing the internal amp chip to shut down (but does not affect the preamp outputs). A test you can do is to fade to one speaker at a time and turn it up to se if it shuts down. Repeat with each speaker until you find the one that causes the fault. Then replace it.
Currently you have the blue wire from your Kenwood head unit connected to the blue wire in the Chrysler wire harness adapter. You need to disconnect this wire, and reconnect it to the blue/white wire coming from your Kenwood head unit instead. You probably already have the remote wire from your subwoofer amp connected there; both wires need to be attached to the blue/white Kenwood remote output.
Your LHS is equipped with a factory amp. The blue wire in the Chrysler harness activates the amplifier, but it's connected to your Kenwood's power antenna activation output; therefore it's only being turned on when the tuner is selected.
