Hey I hoooked up another amp for my mids and i got a loud hissing noise that coordinated with my engine :S. I thought it was my ground wire location so I changed it but problem was still there. I even put the groudn straight to the battery and it stayed. Can anyone help out with other suggestions???
I tried that too, but didnt really make a difference... sill there but just quieter. Could it maybe be where I have the speaker wires? I had to run them through then engine bay and through the fire wall so I could hide the wires.
