Sub Amp "interfering" with all other stock electrical equipment?
I've had this issue before with an amplifier install where I wasn't able to run the Power/Patch cables along separate sides of the vehicle, but in my Maxima I have the power cable running down the left side of the car and the Patch/remote lead running down the right side. What I am experiencing is a lot of "noise/interference" that is noticeable from the second the HU powers on. I will get a "thud" when the amp gets its turn on signal from the HU, but also the other day I noticed it will make the same noise when turning on the headlights, opening/closing the windows, turning on the defrost, etc. Upon closer listening with the volume turned all the way down it seems to have a hum at all times...I am using the HU wiring harness to retain the stock Bose speakers (the one that has 4 line level inputs), as I remember when installing all of them are pretty much turned all the way up. Could this be the cause of what I am experiencing, or is it possibly a bad ground? I am using quality rockford cabling (4 gauge) for both the power and ground, the ground is currently on a stud that was protruding in the trunk with a nut on it, is this a bad location? Any other ideas?

It's a Pioneer 7700MP, the hum is moderately noticeable with the volume all the way down yes. I've been keeping the volume down the past day to listen and it's doing it for everything, wipers/blinkers, etc. the sound is comparable to an electric guitar being plugged into an amp, not the crackly noise just that initial electrical "thud". I hope turning to half still gives me enough volume.

Lawl. It was actually done already else where. I'm just using that guide to do it and offer that service to others.
We all know pioneer could give a rats a about the issue and they are fully aware of it. Though if I could fix it, the 880prs would get more and more appealing again.... blah, make me not do it please.

And here I thought you were holding back some hidden secret knowledge.
That is the primary reason my support went way down for them. First year -ok, bad run. Second year - this needs to be fixed ! Third year - I hate you ! LoL

Well the fix is documented, however I don't know of many people who have done it. It involves opening it up obviously and many people who purchase pioneers are not inclined to doing so. Replacing the pico fuse seems to be a fairly easy job, and replacing it.

If you're unit is not under warranty any longer and you want me to look at it, let me know, after I do the fix on the gf's 8600 I'll let you know.

Wow ya I found a bunch of information on it, damn if I had known about this I would have never purchased the pioneer used...I'm comfortable with taking the unit apart and fixing it myself or even just grounding the RCA's externally for now. Thanks for all the information guys.
