[QUOTE="Jason Sybert, post: 1320158, member: 564205"] I start up my car and my 6x9's which are amped up have alternator noise. I unplugged my RCAs from the amp and it still makes the noise. I moved the ground to several different places. Same noise. And yes I sanded the paint off to shiny metal. Dose anyone know what else I can do. I have done the Big 3, I just replaced the battery for winter, and I checked the cars electrical systen with a DMM it reads 13.9 part of the time. the other part it runs 13.2. The amp is a VR3 2 channel amp and it is 250 watts brigged at 4 ohm. I have it running 500 watts at 2 ohm which according to the factory was okay. I have my gain lower than it should be because the 6x9s are only rated at 225 a piece. the bass boost on the amp is off and the amp is set to flat controls. [/QUOTE]
