i have a d3 hooked up to 2 ma audio amps (a 4 channel and a 2 channel) and i am getting an annoying hiss through my speakers. any ideas how to get rid of this?

 

did you happen to run your power cable over any signal cables or RCAs?

 

nope. rca's and power cable are on opposite sides of the car.

 

are your gains set properly?

 

Is it a hiss in the background that goes away once music starts? Or is a hiss that gets louder when the car is running? Or just an annoying hiss all the time?

 

gains are fine. it's a constant hiss you hear when the volume is relatively low, like at conversational volume where you just want a little music in the background or when you're hearing talk radio or something that doesn't have a beat behind it.

 

i also have the hiss =( only in my rear speakers but u can only hear it when no music is playing.

 

Hmmmm...this is a tough one. Is it from all audio sources? When you adjust the gain does the hissing get louder? If you unplug the rca's from the amp is it still there? Where is the amp grounded and how long is it?

 

well, it's definately louder as i raise the volume, but it gets drowned out from the actual music. the ground is short. i'd say less than a foot and it's right into the metal of the car. the paint was ground off as well. haven't tried unplugging the rca's yet.
