New Stereo DIY

[zlj1989]

Hey everyone. It's been a bad past month for me because my aftermarket stereo was stolen a couple of weeks ago. Worst day of my life! I put the OEM radio back in but I'm just going insane without the kick of my subwoofers. I will be buying a new stereo ASAP but I have decided to put it in myself hoping I can save a few bucks. I've never done this before, so I am asking a little help from you guys. I have two main questions. Can I just buy a harness that goes from the OEM hookup to the aftermarket radio or do I have to do some type of wiring? My other question is a little more difficult. My last radio I had could barely receive any radio stations. I made a post about it a while back but really didn't get any help. The OEM radio receives stations fine but any aftermarket one I had in my Alero barely got any reception. What do I have to buy or do to get my stations. If it's a wiring thing, I would like a step-by-step procedure please and if it's a thing I have to buy, a link to a site where I can buy one would be nice. Thanks everyone for your patience and time. Hopefully someone can help me with this problem.
