I have a 93 es and im using the amp integration harness but im getting alot of ground loop !!

any of you guys had previous experience with this ??

i bought some ground loop isolators (rca) to put them inline with the rca's going to the radio hopefully that fixes it but i made my seperate ground and everything...... if the isolators dont work then im thinking its going to be the factory amp giving me feedback .... WISH ME LUCK

 

Yes pretty much everyone has had issues with this including myself. I installed a Pioneer X920BT double din nav in my 00 ES300. I did not want to bypass my amp and do all that crazy stuff I simply wanted to add the nav, connect the harness and be done with it like you can do in 97% of the cars out there. I to experienced the noise and even though people said the isolators wont do much I tried them anyway. I stumbled upon 2 isolators from Walmart of all places. They were cheap so I figured what the heck. Installed them and to my surprise they eliminated a large amount of the noise!! There is still some noise but it was eliminated so much that you can not hear it while driving and the volume must be all the way down. Im very picky when it comes to stuff and I was very satisfied with how it turned out. So two isolators from walmart did the trick and im happy. The nav system has been great!!
The sound quality is excellent and it was greatly improved over stock when I switched to this aftermarket nav. Hopefully you have the same results as our cars are very different years so there are probably a lot of differences.

Buy two of these...http://www.sonicelectronix.com/item_...mpaign=froogle

I've used them on two installs with great success. The input/output are reversed on the isolators but they function fine that way. Don't forget to ground the brown wires.
