|Installed an amp in my boat and it sounds great when the boat is off.Soon as the boat is running I get a feedback wine from my alternator.You can also hear the blower make a different wine when you run it.It stays a constant volume[though the sound changes with revs]so I can drown it out with full volume but I'm getting tired of only listening to my tunes cranked when running the boatAnyone with any ideas? Thanks|
|Since you get it from the blower as well, I think you should first make sure that you have a good, commonly placed ground on all of your equipment. |
Also, take a look at the following articles from crutchfield. They have some pretty decent step by step instructions. As a last resort, you may need to look at a ground loop isolator/noise filter.
|Did you run a separate power and ground wire from the battery to your amp or piggyback off another power source? Similar to cars… if you have a grounding issue you will hear feedback. |
Have you tried turning the gains down to see if that lowers the noise level too.
|Chaun thanks those links look good.Jeff I do run a seperate power and ground directly off the battery switch system[dual batteries]Should I run into a completely isolated battery from the rest of the system?I really haven't played with the gains while the boat was running yet.|
