i recently installed an amp and a sub to my is. last night as i was closing everything first my speakers died out and everything was still working perfectly. i got tired and didnt feel like troubleshooting it. i woke up this morning to figure out what went wrong i turn my car back on, same problem, so i decided to reset it using the battery. when i did that and i tried to turn everything back on, the nav doesnt turn on at all, the airbag icons off/on are both on, my clock only reads 1:0... my speedometer turns on in the beginning but turns off after a while, the headlights cycle on and off, afs is on, and when i try to start the car a strange humm is heard. i disconnected my amp completely, but the same problem occurs, i checked a few fuses, and all are intact, maybe i missed a fuse? need help asap!

 

There are many fuse boxes. I would check the one in the engine bay on the passenger side and also under the glove box on the passenger side. There are like 3 fuses for the radio. There are also a couple of extra fuses (i believe) in the fuse box in the engine bay on the driver side. In the meantime, I would disconnect the battery and then check every fuse there is in those two boxes I mentioned.
