Bear with me, this is my first car stereo install.

So I'm installing a Sony CDX-MP40 into the 94 Accord. I have all the wires coming from the sony unit to the wire harness that I bought. I did not solder, cuz I was just testing it. I have the ground coming from the Sony unit to a piece of metal. I turn the key it comes on. The unit is not working properly so I go to reset it. I try again and it powers up, works properly, but I do not have the antennae properly placed to test the tuner. I go back to plug the antennae int he back of the Sony Unit and it does not power up at all.

After several attempts, I try to redo the connections, still doesnt work. I notice that the clock does light up either. I go to check the fuse box. I dunno if you guys are familar, but I check the 18th slot and it happens to be blown out. I go to replace it and try the Sony unit again and it still doesnt work.

Anybody have any ideas? Could it be a electrical malfunction? Is it a costly thing to fix? Couldit be the Sony unit? Any suggestions?
