when i was installing my amp i accidentally touched the amp with my screwdriver while connecting ther speaker cables. there was a spark and now i have this buzzing noise when my radio is on. I tried another amp and is the same sound. anyone have any idea what is wrong? I checked all the fuses and it seems fine. thanks.

 

All I can think of is to check the fuses, but since you already did that I'm not much of a help... but try asking this question in the AUDIO section I'm sure people will be able to help you out there better.

 

just take it to the dealer and say the radio started buzzing.
