Interesting. I have a Pioneer deck and plan to use a pioneer amp or too. Hope I avoid any issues.

It's really not too big an issue to stop from buying pioneer. Knowing about it in advance really helps in avoiding any hair pulling. The process to fix the issue takes all of 10 minutes or less. It was frustrating for me because I had to search the problem out for awhile before finding the fix

Ok, so the problem is with the head unit or the amps? Co-incidentally, I have a Pio head unit and may get a pair of Pio stereo amps.

i have a avic -d3 and with the car on or off and the volume at zero i still get a slight hiss through the tweeters.... gains are all off and was dead silent when i had the jvc and the denford 8250!! so it is the deck... output is 1.7volts at 1000ohms not very good. soooooooo anyone want to trade for a denford 8250, pioneer deh-880 or clarion drz 9255??
