speakers/sound system

[96ProDX]

Ok i have a afermarket kenwood deck and rear speakers and now it has this wining osund that gets louder as i apply the gas..(more gas, louder it gets, less gas, quieter it gets) its really annoying and just started and a friend of mine iwth a nissan maxima has the same problem, any suggestions?
thanks.

Do you got one of those neat speed sensor things on your radio? Did you radio get louder when you drove faster before you changed the radio? My friends F-150 has that, so when we sit there its nice and queit, but when he floors it the radio starts blasting. Could be something wrong with that?

from what i know this is derived from poor grounding.

yea idk its weird, i noticed with my car it only happens when the subs/amp are hooked up but my friend with the maxima doesnt have a system and his does it. I checked the grounding for the amp myself and it looked fine and i had in a car audio shop like a month ago and they said it was fine, what u mean by speed sensor? iv never heard of that.
Thanks.

that never happened to me and i installed all my stereo system: deck, speakers, subs, and amp

It could be
a) Your audio signal wires are too close to your power wires at some point
b) A bad ground somewhere

check the ground on your head unit, get a ground loop insulator for your RCA's if it still doesn't go away.

what if i said it only happens when i have a system hooked up (amp,subs)... bad amp ground?

It could be how you have your amp grounded. I grounded mine to the bolts holding the rear seats on. Gotta make sure there isn't paint on the surface your trying to ground to. I have my power and RCA wires on opposite sides of the car.
