I have a '87 924s that I recently installed some audio goodies into.I wired in the new HU and single 10.I did everything right, I soldered everything,electric taped it,the battery wire has a fuse,etc. I believe i played the amp to long with the car off and might have had it a little too low. I went to start it and it would turn over once or twice and I would have to turn it all the way off again. Long story short It fired up and i let it run for 10-15 minutes.The amp and and radio were on,But I didnt have anything playing.I tried to start later and no cigar, not even trying. the only noise sounds like its coming from the fuse/dme area and there is some sort of noise from the back too i think.The battery isnt even a month old and i disconnected and cleaned the cables and let the battery charge over night.I said my prayers and turned the key,same story different day.The onlything that dims when I turn turn the keys is the headlights which I think is normal,and i disconnected the amp and still nothing,please someone be my hero and help me out it kinda has me beat

Verify the battery took a charge, once that verified check the positive and ground conections.
Another note: the plastic ignition switches break easily when old in the early 944s and 924s.

The ignition switch is good and the battery is good and I tried hitting it but it didnt work

You could see if the battery will start a different car by using jumper cables after disconnecting the battery in that car. This will tell you if the battery really has sufficient charge or not. I'm betting your battery has a dead cell.
