a fuse blown somewhere, is there an aftermarkt amp on the door speakers or a stock external amp on them?

 

[ynottony93]

i've checked all fuses and they're good, i'm pretty sure the car stereo is bone stock so no amps

You checked fuses on both the car and headunit?

 

[ynottony93]

how do you check the headunit fuse?

You checked fuses on both the car and headunit?

the only time ive had those blow is when you let the rem. wire going to your amp touch a ground while the head unit is on

Pull the HU out, there should be a small 15a fuse in the back somewhere. Atleast there is on mine.

yea just took it apart.. no luck finding the fuse :\

Mentioning HU model # and posting pics might help.

Once i had the same problem and it was the wiring, I had no sound but hissing. => smthing tells me u did not wire it properly.
