I was putting in a Sony CDX-GT42IPW and when i was installing it i blew a fuse when i was testing it out because the hot wire touched the radio. it was the radio fuse and i didnt have a spare, so i just switched the power door and window fuse in to see if it works, and it powered on and everything. The radio works and everything, but there is no sound with the AUX, PD (iPod in) or CD/MP3 player. Was messing with it for a few and then i heard a clicking noise, not coming from the speakers. im not sure if i screwed something up or what, but i was wondering if anyone has had similar problems or knows possibly what may be going on. thanks.

 

i checked all the fuses on the dash and they were all fine except for the one i blew, which i replaced. now sometimes when i start my car, it revs then slowly drops down. did i fry my ECU or something?
