Installing the head unit was a bit tricky. I had to cut part of the dash behind it in order for it to fit. I had to do the same on my brothers 97 Grand Am GT as well. As for installing the amp, thats easy, only tricky part is running the wires, but anyone can accomplish that if the know how to hide stuff.
if you want to know, the head unit is the KDC-MP822. Changer is the KDC-C719. And the Sirius tuner is the KTC-SR902. As for the Sirius antenna, it is the Terk SIR3. I tried mounting it in the trunk, but it woudln't keep a signal. So it had to go on the roof.
