    these are easy

    1) pull out the speaker covers by using a falt head screwdriver.
    2) push off the covers.
    3) in the trunk push out the clips in back of the speaker holder.
    4)remove the holder and replace it on the new speckers.
    5)snap the speaker holder back in and replace the covers
    6) next your going to have to wire it up and your done.

    it depends on the phone really if you have a aux jack you can just get a cord and plug it in or just get an adapter. you can get one at any eletronic store.

    not really sry i put 4X6's in the front some good ones though, infinity's, your best bet is to look around. I remeber seeing someone put 6 1/2s in the front with some pictures and steps on how to, but I dont rember the site. Just look for it on google.

    do you know how to install an aftermarket stereo in a 2003 Oldsmobile alero and if there is something special we have to do so something doesnt stop working?
  • redaleroredalero Member Posts: 4
    here's what i did:
    1. remove clip from your shifter knob. it is on the side closest to your a/c controls
    2. remove the handle from shifter and remove the piece that says P R D 3 2 1. be careful when removing there is a connected wire to it.
    3. remove the black frame from aroun stereo/climate controls. there will be a crap load of wires connected to it but i managed to get it out with out removing any wires. and that is about it hope this helps

    ok did it make anything not work after you were done? I was told that after I put the aftermarket one in that the factory stereo wouldnt ever work again

    It is the anti theft device in the stereo called theft lock some aleros have it some dont i believe it should say on your stereo. You CAN get it to work if you put it back. Its not that the stereo will not work it will ask for a password which if you dont have you can get from general motors. I never tried it but i saw this in another forum.

    Ok now how do I take out the factory radio? What kind of an installation kit do I need to get for it? Or where I could buy it from? Do you have any pictures of while you were installing it or a diagram or anything.

    I'm trying to install new after market speakers in the rear of my 2003 Oldsmobile Alero. The issue is that the new speakers only have two connections (+,-) but the factory wiring harness has four wires. I cannot find an adapter that will fit this configuration, so I plan on just connecting one positive and one negative and taping the others off. Will this work, and if so, which wires are positive and negative? Also, which ones should I connect?
