I recently replaced all four speakers with some new Pioneers. That went great and they all worked perfect with the stock radio. Then I wired in a new aftermarket head unit. I know all the wires were spliced and covered correctly. Then the fuse for the radio blew. I replaced the fuse and it blew again. Then I put a 10 amp fuse in instead of a 7.5 and it didn't blow that one but it also didn't turn on still. I then left it alone and I flipped the headlights on and the dash lights flashed on and then went out and now they don't work. I checked the fuses and the relay and they are both good. Then I was out last night and got pulled over because none of my parking lights and brake lights work. So I cant drive my car and I really need it. Any help would be so greatly appreciated. I'm clueless as to go about finding the issue. Thank you!!

 

Please!!! I really need my car to go to work.

 

Please don't take this the wrong way.

Step back and think about what you did - and then the result: Fuse blowing.

Now when you turn on the headlights - another fuse blows.

 

But all the fuses are now replaced. And everything still doesn't work.
