  • Need Help With Cd-Power Line

    My constant power line going into my head unit has died on me. What i did was just ran a wire to my batterie postitive side. It worked fine for about a few days, but now, whenever i press the gas kinda hard or start moving from a stop, my cd will skip. Now this is an mp3 cd, which means it should not skip. What i am thinking is, when i press the gas, the alternator has to work harder, so it takes more juice, thus taking away from the power that the deck gets, sound someone right?
    So is there a way, or a regulator, or something that i can do to fix this? Would a simple in-line 10a fuse work?

    Thanks for the help guys.

      Where is the power line coming from? If it is unregulated, you might be sending too much voltage into the cd player. Your car's electrical system will spike when the RPMs go up. This is unhealthy if the cd player is expecting a clean 12v supply.

        Almost all HUs don't need regulated voltage.

          It is coming directly from the battery like i said. How can i regulate the voltage? An in-line fuse? If so, i have the amp hooked up with a 60a fuse. Can i just run the cd player off that?

            No, the fuse is not for regulating the voltage. You could do that with the voltage reglator, but you'd need too many of those, as you need a lot of Amps.

              Does it happen if the car is stopped and you just rev it up?

              There is a voltage regulator inside the alternator on that car. If the head unit is having problems only when you rev the engine than the internal regulator in the alternator could be bad, letting the voltage get too high. The battery warning indicator on the dashboard should be coming on if and when this happens.
              You may also want to use a volt meter and check the voltage at the battery while someone revs the car up. You could also do this at the head unit connection. Anything over 15 volts or so is too high.

              It could also be a bad battery or head unit. What head unit is it, anyway?

              Peace.
