  • i think i know where noise is comming from (ground: headunit vs carputer)... BUT

    im using my stock head unit/deck... (honda accord 2003) which is grounded somewhere, i dont know where...

    my carputer is also grounded. i only have one ground to my ITPS. so that should be fine.


    i have a ground loop, and to fix this i should ground the stock deck and the carputer at the same spot. RIGHT????


    how do i do this??

      Your not going to get many answers at 3:00AM - 7:00AM.. Someone will help you out though..

      I do had / have alternator noise. It first was when I just had my carputer and I ended up buying a ground loop isolator from Walmart ($12). That fixed it... Now that I've installed an amp it's back...

        Try grounding your audio to the headunit chassis

          hehe. i remember you telling me to ground my audio before..

          but i dont know how since my rca cable doesnt have grounding wire with it

          the only ground i have is for my whole carputer... should i ground the whole thing to the headunit chasis?

            No.

            Run a wire from the very base of your headphone jack. (I you look at a heaphone jack there are 3 seperate metal parts. The top two are left and right audio, the one at the base is the ground. Run this to the HU audio ground or to the HU Chassis.

            If you can't work that, then get RCA's with ground wires on.
