    when the volume is down, only when the car is ON (driving). when I give gas the static becomes louder. the louder i turn the volume the softer the static noise gets. it also happens when the volume is at zero and when i change songs.

    i just installed the deck in my car tonite.

    what could this be from and how can i prevent it???

    Sounds like you have a grounding problem. Did you just tie the ground wire on the deck directly into the wiring harness or did you connect it to a solid ground on your chassis within your dash? If not, do so, after roughing up the area with a file or wirebrush, and then using a star washer to cut into the metal.

    i think 80 percent of the problems that come here are ground related, we need to make a master thread regarding common issues that come in here, like an FAQ

    hmmm, i think i might be on to something

    i grounded it and it still happens... except it didn't happen when the deck was pulled out so im thinking there is a wire that is touching metal ??? im gonna pull it out tomorrow after school and check it out.

    Now it sounds like there is crosstalk going on between wires. Maybe try routing the wires differently behind the deck, zip tie the harness wires together and then whenever they cross any other wires try to make them cross at 90 degree angles wherever possible. This can be accomplished through zip ties at the intersections going diagonally. Or there might be a light short to the chassis. You MIGHT have to buy a ground loop isolator.
