[quote name="negri21"]k, i figured out on my own what i need to get i guess. i guess i will need a Ground Loop Isolator. But hell if i know where that goes. I dont do many installs. and my install guy didnt have one. so can someone please help me? i need to get this, that squeeling, humming, noise- is killing me!! please email me at airnegri@hotmail.com[/quote] You can buy them at radio shack or PAC makes one that you can probably find on E-bay. They seem to make a huge difference with the Z-1, especially if your using power amps.

[quote name="zeros"]hi i was wondering how to ground loop your rcas to your headunit? just connect a wire from the headunit to the rcas? thanks[/quote] Just read you posts. Read mine about Z-1 with power amps. You can try runnning a ground wire from the same ground of your power amps to the ground wire of the head unit. Do not use the car's wire harness ground wire. A much simpler solution is to buy the PAC SNL-1 ground loop isolators for as many sets of high level outputs that your usung. My Ford truck was set up with 2 amps so I bought 2 on e-bay for a total of $26. You simply plug

[quote name="logan0171"]My speakers are driven by JL Audio amps without any problems. How long does the sound last? Is it a quick 'thump' or does it continue for a few seconds? Are you driving the amps using the high level or low level outputs of the Z1? Are you using the correct turn on lead for the amps? Are you sure that none of the unused wires from the wiring harnesses are accidentally grounding to any metal behind the head unit? These are just a few things that come to mind.[/quote] Thanks Logan0171 The loud thumping and buzzing is constant and seems to be coming only from t
