haha, it all works, no more whining, no more buzzing, no static. I rewired from where the stock amp use to be, back to my aftermarket amp with insulated speaker risers coming from the stock speaker risers with rca connectors. no hi/lo adaptors, no ground loop isolators, and no more sounds. I will take a pic tomorrow and show wtf i did.
thanks for the help too!

 

the problem could be either a bad/loose ground location, a ground loop, or the gains and level adjustments on the amp could be too high.

 

Nice! Its amazing how well things work when they are properly installed. [:-] Just joking!

 

How do u have your amp hooked up with the rca's? Did u use a converter. That might be the problem a bad converter. I have my amp ground located right underneath my rear seat on one of the bolts. If u need a pic lemme know. But check your converter if you are using one. I had the problem and had to buy a new one. Fixed it right away.

 

well my buddy had that happen when he ran the rca's and power through the same side. he then ran them seperately and that noise was gone. i just put in my infinitys last week and ran it to a 4 ch amp and im getting the exact same problem as you. im going to an audio shop tomorrow morning the guys there will fix it in no time because i already messed with all the grounds and that didnt help.

 

the sound you are hearing is called alternator whine it is caused by 2 things 1 bad ground 2 the power wire and the rca for a full range (your 4 channel) can't run on the same side as the car. if they cross paths for an reason try to do it at a 90 degree angle.

 

if he ran the power and speaker wire for the front door panel speakers, couldnt that be the problem too if they crossed?
