Ok so I bought a 89 5spd supra N/A targa the other day and it came with a really nice alpine headunit but it isnt hooked up to the speakers right so I am wondering how to get it out so I can fix it. It turns on but no music so I am guessing one of the wires is either plugged in wrong or not at all. I need to know how to get the head unit out. And yes I have "searched" and have come up empty. Thanks for your time.
