Hullo!
If you're using the standard ISO connectors the Alpine comes on, the likely problem is that the switched and permanent +12v wires are backwards. For some reason, Alpine have seen fit to wire up most of their older head units like this.
Check the voltages on the red and yellow wires in the car. I'll bet my status as "someone who knows something" that you'll find they're backwards to what the Alpine's expecting
If this is the case, and your wiring loom (on the stereo bit) has bullet connectors on the red/yellow wires, you can switch them. If not, then you can remove the wires from the ISO connector using a small screwdriver to flatten off the connector pins.
Hope this helps
