Installed a Sony Xplode in my 99 Blazer. Has the proper harness and all the wires are hooked up correctly. It previously had a Bose system as a factory model and played through the speakers just fine. Now that the Xplode is in, the speakers don't work. I've read that people say the radio is fried, and it's not. It was previously in my cabrio, and after hooking it up once more to the older car, it works just fine. Speakers and all. What am I missing here?
The Bose system is complex - it has an amplifier separate from the Bose compatible radio. This amplifier takes low level audio signals from the radio, not full driver outputs from a replacement radio, and by trying to use the replacement radio you may have blown the amplifier. If that is the case, you may not be able to go back to the original radio.
The only option you may have with the replacement will be to find the Bose amplifier and bypass the connections to feed the replacement radio outputs directly to the speakers. This may not be as simple as it sounds, as distribution to the various speakers comes from the amplifier, not the radio, and the wiring from the amplifier to the radio may not have all the wires you need. Before going on, you had better get a wiring diagram for the Bose system (service manual or Alldatadiy.com).

More than likely with a 2003, the speakers that cut out are in the door or doors. Do they cut out of both speakers?
If they cut out of one, then you may have an intermittent speaker ( the wire to the cone becomes partially connected)
If both speakers turn off at the same time and you hear NOTHING on all speakers, then you more than likely have an intermittent connection on the radio itself and probably replacement is probably cheaper than fixing the radio.
One more thing
Factory radios sometimes have an amplifier in them. Sounds funny but they call the Radio in the dash the Head Unit and the amplifier is buried in the dash. You could have a bad amplifier or a loose power connection to it, but that is very unlikely.
Hope this helps.

try different speaker if works .its the speaker. if another speaker does the same .your radio is the problem.

This sounds like the CD is dirty, try getting a CD Cleaner disk, they are economical enough.
After years of use the lens on the CD can get dirty, one or two cleanings sometimes clears this up.
If you smoke in the car the lens will need continual cleaning every 3 mos or so.
Hope this works out for ya.

If you go onto the Crutchfield .com web site and click on their link - "outfit my car" it will list your factory speakers. The site will ask for info regarding your particular vehicle: 2 door, 4 door, with bose system, etc. The speaker sizes may be the same for all options. You can find out by clicking on all the options to compare.
