I was driving listening to music at a fairly loud level when the inline fuse on my PPI PC4400 amp blew, well I think it blew as it looked intact but when I replaced it the amp came back on, agter it was replaced, the is now a ton of alternator noise from all speakers at all times, it being most noticable when the car is stationary. I checked the grounds and RCA's but find nothing different. . . Could something have happened to the amp to cause this sort of thing? Thanks for any help.

 

Do you have the RCA cables on one side and the power cable on the other? Some amps cut off when they overheat I don't think that it was the fuse. Make sure all the ground connections are good.

 

I know it was a fuse as when I put the power cable from the other amp to the dead one, it turned right on. . . So the only thing it could have been was a fuse, which when I replaced it, it turned right back on. . .

The RCA's run down the center of the car, and I didn't have any sort of noise before this happened, but I think I have isolated that it has something to do with the EQ. . . When it is on there is noise, when it is off there is none. . . I have checked the ground, and actualkly regrounded it, and I am having no luck, any suggestions?
