  • Reply ModifiedLife October 14, 2009 at 1:18 am

    Clark, your 1999 Cadillac Catera may have a factory amplifier that needs to be turned on by your radio. The car stereo amplifier trigger wire has to be wired up to turn on your factory amplifier. Unfortunately, we do not have this information but maybe someone from the Modified Life community can post that information here. Hope this helps. Good luck.

  • Reply ModifiedLife October 24, 2011 at 8:07 pm

    James, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 1999 Cadillac Deville may have a factory amp that needs to be turned on by your after market radio. The car radio amplifier trigger wire has to be wired up to turn on your factory amplifier to output sound from your speakers. Double check that your 1999 Cadillac Deville amp turn on wire is connected. Hope this helps. Good luck with your 1999 Cadillac Deville stereo installation.
