Andy at crutchfield tells me this

You are limited by the depth available (6.327") in your 1999 Oldsmobile Alero, and most of the aftermarket receivers are not listed as a good fit for this reason. You may be able to work around these depth limitations, but this will fall into the category of a custom installation and I'm afraid we can't be of much help there.
Of course, everything you purchase from Crutchfield comes with our unconditional 30 day, money back, Total Satisfaction Guarantee. You get a whole month to make sure you have the right equipment for your needs.

Im not sure if i would know how to do a custom fit?... If i did would the deck stick out more then normal?

Thanks for any help
