at low volumes, i can hear static. when i rev my car, the static ticks faster. what should i be checking? i think i should recheck the ground wire to the stereo. i noticed it after i had my timing belt and water pump replaced, but i don't think that has anything to do with the stereo. btw, the stereo is an alpine cda-9835 and the car is a 91 honda accord. thanks guys.

 

make sure power lines arent running close to the RCA's or any speaker lines.

 

check the ground on the radio. if you speakers are running on an amp do what flyromeo3 said and check the ground on the amp.

 

yeah, it was the power cable running too close to the rca cables in the back of the radio. when i pulled out the radio, the noise went away, and when i put it back, the noise came back. it turned out that the power cable was too close to the rca cables. thanks guys.
