I tried regrounding the amps directly to the negative terminal of the battery but the noise was still there. I tried all sorts of things and eventually just ran an rca from my clarion dvd player to the amps and the noise disappeared! So after doing a search about the 860's noises problems I am pretty sure that it is the culprit. But before I contact Pioneer I have some questions for other people with the 860 noise problem. Do I have to send the unit into Pioneer or can I get it fixed at an authorized service center? I read in somewhere on this forum that I should say it was gift and I don't have a receipt since I bought it unauthorized. Is there anything else I should say or avoid saying in the e-mail? Thanks.</p></blockquote><p></p>
