  1. i read your your 2001 oldsmobile alero radio wiring but it doesnt tell what the extra brown, black and two purple wires are for. can anyone please help me?

  2. Lt, the radio harness does not provide a switched power source. Run a wire to the steering column and use the brown wire in the ignition switch harness. Hope this helps. Good luck with your 2001 Oldsmobile Alero stereo installation.

  3. I have a 2001 olds alero and I have replace the stock stereo and have found that the sound out put is greatly decreased.. I have heard that to by pass the Monsoon amplifier I need to just run new speaker wires. is this true or have I missed something?
